Previously, rdma_restrack_add(&id_priv->res) was invoked unconditionally even when cma_acquire_dev_by_src_ip() failed, passing a resource with a NULL dev pointer and triggering the WARN_ON assertion in res_to_rt(). Fix this by only adding the resource to restrack when acquiring the device succeeds. | ||||
| CVE-2026-90220 | 1 Linux | 1 Linux Kernel | 2026-09-20 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: ALSA: seq: Don't leak the extension cell pointer in the bounce payload The bounce_error_event() embeds the failed event in the bounce payload by pointing data.ext.ptr at it. When that event is a queued variable-length event, its own data.ext.ptr holds the address of its first extension cell, put there by snd_seq_event_dup(). The payload goes out verbatim through snd_seq_expand_var_event(), so the address reaches userspace. That is the same address commit 705dd6dcbc0e ("ALSA: seq: Clear variable event pointer on read") removed from the event header. The read path still clears it there, just above the call that expands the payload. Embed a sanitised copy instead, treated exactly as snd_seq_read() treats the header. A stack copy is enough because delivery is synchronous and snd_seq_event_dup() copies before returning. An unprivileged client reaches this by setting SNDRV_SEQ_FILTER_BOUNCE, queueing a variable-length event to a port that does not exist and reading the bounce back. Eight bytes on 64-bit, from its own pool. | ||||

| In the Linux kernel, the following vulnerability has been resolved: nfc: nci: fix use of uninitialized memory in CORE_INIT_RSP parsing nci_core_init_rsp_packet_v1() and nci_core_init_rsp_packet_v2() parse the CORE_INIT_RSP packet without validating that the skb contains enough data. A malformed response (e.g. injected via virtual_ncidev) can declare a large num_supported_rf_interfaces while providing insufficient data, causing reads of uninitialized slab memory. This is later used in nci_init_complete_req(), triggering a KMSAN uninit-value warning. Add skb length checks before accessing packet fields: - Validate the skb has at least 1 byte for the status field. - Validate the skb can hold the fixed-size header before parsing. - In v2, bounds-check each variable-length rf_interface entry and its extension parameters within the parsing loop. - In v1, verify the skb is large enough for both the variable-length rf_interfaces array and the trailing rsp_2 structure. | ||||
| CVE-2026-90225 | 1 Linux | 1 Linux Kernel | 2026-09-20 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: nfc: llcp: read llcp_sock->local under the socket lock in getsockopt nfc_llcp_getsockopt() read llcp_sock->local before lock_sock(sk) and then dereferenced the cached pointer inside the locked region. llcp_sock_bind() assigns and clears llcp_sock->local under the same socket lock, dropping the last reference on its error path. A getsockopt() racing an in-flight bind() can observe the pointer, block on lock_sock(), and then dereference a freed nfc_llcp_local once bind() has unwound. Move the llcp_sock->local read and the NULL check inside the lock_sock(sk) region so bind() cannot mutate or free the pointer between the load and the use. | ||||
| CVE-2026-90279 | 1 Linux | 1 Linux Kernel | 2026-09-20 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: md/raid5: round bitmap stripes with sector division raid5_bitmap_sector_map() aligns the array range to full RAID5 stripe widths before converting it to component sectors. That width is chunk_sectors multiplied by the number of data disks, and it is not always a power of two. Reproduce with a 4-disk RAID5, 1024-sector chunks, and three data disks. The full-stripe width is 3072 sectors. For a one-sector write at array sector 3072, correct rounding gives array range [3072, 6144), which maps to component range [1024, 2048). The old round_down()/round_up() logic instead gives [1024, 4096), which maps to [0, 1024). Use sector_div() based arithmetic so the rounded range is aligned to the actual RAID5 stripe width. The deterministic mapper test now reports the fixed component range as [1024, 2048), while the old mask-based range was [0, 1024). | ||||

| In the Linux kernel, the following vulnerability has been resolved: phy: sunplus: fix error handling in sp_uphy_init() Fix the error paths of sp_uphy_init() to undo exactly what each stage did: return directly if clk_prepare_enable() fails, release only the clock if reset_control_deassert() fails, and jump to err_reset if update_disc_vol() fails so the clock and reset are not leaked. | ||||
| CVE-2026-90289 | 1 Linux | 1 Linux Kernel | 2026-09-20 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Resize MST HDCP per-connector arrays to 32 AMDGPU_DM_MAX_DISPLAY_INDEX is 31. It suggest a maximum number of 32 connectors. But the way it's used is like MAX_DISPLAY_COUNT. Hence we're off by one with DRM core, which supports a max of 32 connectors. Rename AMDGPU_DM_MAX_DISPLAY_INDEX to AMDGPU_DM_MAX_DISPLAY_COUNT to match its actual use, and increase the size to 32 to match the originally intended size. | ||||
| CVE-2026-90392 | 1 Linux | 1 Linux Kernel | 2026-09-20 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: bpf: Fix potential UAF when reading bpf link info In bpf_link_show_fdinfo and bpf_link_get_info_by_fd, link->prog is accessed without holding any locks. If the prog is concurrently replaced via bpf_link_update, the old prog can be freed, leading to a potential UAF issue. Fix this by accessing link->prog under RCU protection to safely fetch the pointer and guarantee its lifetime while reading its fields. | ||||
| CVE-2026-90414 | 1 Linux | 1 Linux Kernel | 2026-09-20 | 9.1 Critical |
| In the Linux kernel, the following vulnerability has been resolved: IB/isert: reject PDUs declaring more data than was received isert_recv_done() hands each received PDU to the opcode handlers without ever looking at wc->byte_len, the number of bytes the HCA actually placed in the receive descriptor. The handlers then copy that many bytes - the data-segment length the initiator declared in the BHS (ntoh24(hdr->dlength), via the derived unsol_data_len / imm_data_len) - out of the fixed-size descriptor: isert_handle_iscsi_dataout(): sg_copy_from_buffer(sg_start, sg_nents, isert_get_data(rx_desc), unsol_data_len); isert_handle_scsi_cmd(): sg_copy_from_buffer(cmd->se_cmd.t_data_sg, sg_nents, isert_get_data(rx_desc), imm_data_len); Because the declared length is never checked against wc->byte_len, an initiator can declare a data segment larger than the bytes it actually sent (and larger than the descriptor) and cause an out-of-bounds read of the receive buffer. Nothing upstream of isert closes this door: - __iscsit_check_dataout_hdr() bounds the inbound payload against conn_ops->MaxXmitDataSegmentLength (MXDSL) - a transmit parameter, used here for the inbound check. - iscsi_set_connection_parameters() sets ops->MaxXmitDataSegmentLength = ops->TargetRecvDataSegmentLength; and TARGETRECVDATASEGMENTLENGTH is absent from the min()-clamp list in iscsi_check_acceptor_state(), so the value the initiator declares is adopted verbatim (type range 512..16777215). The initiator effectively raises its own ceiling. - isert never clamps the negotiated value to its own fixed receive descriptor (ISER_RX_SIZE, 9216 bytes), so the target core's bound and the descriptor size are unrelated. The imm_data_len == data_len path is more than an over-read: it aliases the receive descriptor via sg_set_buf() and passes it to the backend as the data source for the SCSI WRITE, so an over-declared length causes heap contents past the descriptor to be written through the backend to the backing store. The backend is the victim of the oversized scatterlist isert hands it, not the cause; no read-back of the written bytes was demonstrated. Trigger: after login completes (full feature phase), an initiator that has declared a large TargetRecvDataSegmentLength and a FirstBurstLength that permits unsolicited/immediate data sends a PDU whose declared data-segment length exceeds what was received. With KASAN: BUG: KASAN: slab-out-of-bounds in sg_copy_buffer+0x150/0x1c0 Read of size 4096 at addr ffff888109720800 by task kworker/1:0H/25 Workqueue: ib-comp-wq ib_cq_poll_work Call Trace: sg_copy_buffer+0x150/0x1c0 isert_recv_done+0xba6/0x2390 __ib_process_cq+0xe1/0x390 ib_cq_poll_work+0x46/0x150 isert_recv_done+0xba6 resolves to isert_handle_iscsi_dataout() (ib_isert.c:1160), inlined through isert_rx_opcode(). Validate wc->byte_len against the framing in isert_recv_done() before the PDU reaches any handler, and reinstate the connection if it is short. Because the test compares without subtracting the header length, it also rejects PDUs shorter than the iSER and iSCSI headers, which would otherwise be parsed out of stale descriptor contents. The login handler rejects PDUs shorter than ISER_HEADERS_LEN (commit 29e7b925ae6d ("IB/isert: Reject login PDUs shorter than ISER_HEADERS_LEN")) but does not bound the declared length either; that is fixed in the next patch. The data handlers had no length check at all. isert reads the data segment from a fixed offset: isert_get_data() returns the iSER header plus ISER_HEADERS_LEN and makes no adjustment for an AHS. The bytes the handlers touch are therefore exactly [ISER_HEADERS_LEN, ISER_HEADERS_LEN + dlength), and comparing that sum against wc->byte_len bounds precisely the region that is read. An AHS term would only make the test stricter without bounding anything furth ---truncated--- | ||||

| In the Linux kernel, the following vulnerability has been resolved: nilfs2: prevent out-of-bounds read in super root block parsing super-root inode metadata size is trusted before nilfs_read_inode_common(). Reject super-root inode sizes whose computed on-disk footprint exceeds the filesystem block size. This prevents malformed filesystem images from making nilfs_read_inode_common() read past the end of the super-root block. [ryusuke: clarify the commit title] | ||||
| CVE-2026-92488 | 1 Linux | 1 Linux Kernel | 2026-09-20 | 7 High |
| In the Linux kernel, the following vulnerability has been resolved: RDMA/erdma: complete object teardown when the destroy command fails erdma_destroy_qp(), erdma_destroy_cq(), erdma_dereg_mr(), and erdma_destroy_ah() returned early when erdma_post_cmd_wait() failed, leaking the queue buffers, MTTs, doorbells and the STAG, QPN, CQN and AHN identifiers. A command timeout clears ERDMA_CMDQ_STATE_OK_BIT and permanently disables the command queue, so no retry can succeed; the RDMA core keeps the object after a failed destructor and forced uverbs cleanup then nulls the pointers, making the resources unreachable. Warn on failure but release every software-owned resource and return success, since during terminal destruction the hardware command result is only diagnostic. | ||||
| CVE-2026-93137 | 1 Linux | 1 Linux Kernel | 2026-09-20 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: bpf: Fix use-after-free on mm_struct in bpf_find_vma() bpf_find_vma() reads task->mm and calls mmap_read_trylock(mm) without holding a reference on the mm. On a foreign task, a concurrent exit_mm() can free the mm_struct between the lockless read and the trylock, resulting in a use-after-free. mm_struct is not SLAB_TYPESAFE_BY_RCU. For the current task, task->mm is stable. For a foreign task, pin the mm under task->alloc_lock and release it with mmput_async(), mirroring commit d8e27d2d22b6 ("bpf: fix mm lifecycle in open-coded task_vma iterator"). Use spin_trylock() instead of get_task_mm() so BPF context does not block on alloc_lock. Reject irqs-disabled contexts and !CONFIG_MMU on the foreign-task path because dropping the mm reference is not safe there. Race: CPU0 (BPF program) CPU1 (exiting task) ============================ ========================== bpf_find_vma(foreign_task): mm = task->mm exit_mm(): task->mm = NULL mmput(mm) -> frees mm_struct mmap_read_trylock(mm) // UAF on mm | ||||
| CVE-2026-89093 | 2 Wordplus, Wordpress | 2 Better Messages – Chat Rooms, Group Chat, Private Messages & Ai Chat Bots, Wordpress | 2026-09-20 | 5.3 Medium |
| The Better Messages – Chat Rooms, Group Chat, Private Messages & AI Chat Bots plugin for WordPress is vulnerable to Information Exposure by Spoofing in all versions up to, and including, 2.15.33. This is due to the `is_ai_bot_user()` function identifying privileged internal AI bot accounts by performing a prefix check for `'ai-chat-bot-'` against a guest record's stored IP address, which is populated verbatim from the client-controlled `X-Real-IP` request header during unauthenticated guest registration. This makes it possible for unauthenticated attackers to register a guest identity that the plugin treats as its own internal AI bot, bypassing the per-room role allowlist, draft-status check, and join filters — which are all short-circuited by the bot check in `user_can_join()` and `user_can_read()` — to join administrator-restricted chat rooms, post messages into them, and read the private message history of other users. | ||||
| CVE-2026-9858 | 2026-09-20 | 4.3 Medium | ||
| The Partial Shipment for Woocommerce plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 3.4 via the wxp_order_shipment, wxp_order_item_shipment, and wxp_order_set_shipped AJAX actions. This is due to the AJAX handlers in woocommerce-partial-shipment.php (registered at lines 60–62 and implemented at lines 228, 263, and 291) lacking both capability checks and nonce verification, and not validating the calling user's ownership of the supplied order_id. This makes it possible for authenticated attackers, with Subscriber-level access and above, to read arbitrary order item details (names, quantities, shipped counts) belonging to any customer and to modify the shipment status / shipped quantities of any order, which can also trigger order status transitions via the wxp_order_status action. | ||||
