| CVE-2026-53190 | 1 Linux | 1 Linux Kernel | 2026-08-12 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/virtio: fix dma_fence refcount leak on error in virtio_gpu_dma_fence_wait() dma_fence_unwrap_for_each() internally calls dma_fence_unwrap_first() which does cursor->chain = dma_fence_get(head), taking an extra reference. On normal loop completion, dma_fence_unwrap_next() releases this via dma_fence_chain_walk() -> dma_fence_put(). When virtio_gpu_do_fence_wait() fails and the function returns early from inside the loop, the cursor->chain reference is never released. This is the only caller in the entire kernel that does an early return inside dma_fence_unwrap_for_each. Add dma_fence_put(itr.chain) before the early return. | ||||
| CVE-2026-46461 | 1 Dell | 1 Server Hardware Manager | 2026-08-12 | 7.8 High |

| CVE-2026-64182 | 1 Linux | 1 Linux Kernel | 2026-08-11 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drivers/base/memory: fix memory block reference leak in poison accounting memblk_nr_poison_inc() and memblk_nr_poison_sub() look up a memory block via find_memory_block_by_id(), which acquires a reference to the memory block device. Both helpers use the returned memory block without dropping that reference, leaking the device reference on each successful lookup. Drop the reference after updating nr_hwpoison. | ||||
| CVE-2020-3458 | 1 Cisco | 10 Adaptive Security Appliance Software, Firepower 1010, Firepower 1120 and 7 more | 2026-08-11 | 6.7 Medium |
| Multiple vulnerabilities in the secure boot process of Cisco Adaptive Security Appliance (ASA) Software and Firepower Threat Defense (FTD) Software for the Firepower 1000 Series and Firepower 2100 Series Appliances could allow an authenticated, local attacker to bypass the secure boot mechanism. The vulnerabilities are due to insufficient protections of the secure boot process. An attacker could exploit these vulnerabilities by injecting code into specific files that are then referenced during the device boot process. A successful exploit could allow the attacker to break the chain of trust and inject code into the boot process of the device, which would be executed at each boot and maintain persistence across reboots. | ||||

| CVE-2022-20742 | 1 Cisco | 2 Adaptive Security Appliance Software, Secure Firewall Threat Defense | 2026-08-11 | 7.4 High |
| A vulnerability in an IPsec VPN library of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to read or modify data within an IPsec IKEv2 VPN tunnel. This vulnerability is due to an improper implementation of Galois/Counter Mode (GCM) ciphers. An attacker in a man-in-the-middle position could exploit this vulnerability by intercepting a sufficient number of encrypted messages across an affected IPsec IKEv2 VPN tunnel and then using cryptanalytic techniques to break the encryption. A successful exploit could allow the attacker to decrypt, read, modify, and re-encrypt data that is transmitted across an affected IPsec IKEv2 VPN tunnel. | ||||
| CVE-2020-3186 | 1 Cisco | 25 Asa 5505, Asa 5505 Firmware, Asa 5510 and 22 more | 2026-08-11 | 5.3 Medium |
| A vulnerability in the management access list configuration of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to bypass a configured management interface access list on an affected system. The vulnerability is due to the configuration of different management access lists, with ports allowed in one access list and denied in another. An attacker could exploit this vulnerability by sending crafted remote management traffic to the local IP address of an affected system. A successful exploit could allow the attacker to bypass the configured management access list policies, and traffic to the management interface would not be properly denied. | ||||
| CVE-2021-34794 | 1 Cisco | 18 Adaptive Security Appliance Software, Asa 5505, Asa 5505 Firmware and 15 more | 2026-08-11 | 5.3 Medium |
| A vulnerability in the Simple Network Management Protocol version 3 (SNMPv3) access control functionality of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to query SNMP data. This vulnerability is due to ineffective access control. An attacker could exploit this vulnerability by sending an SNMPv3 query to an affected device from a host that is not permitted by the SNMPv3 access control list. A successful exploit could allow the attacker to send an SNMP query to an affected device and retrieve information from the device. The attacker would need valid credentials to perform the SNMP query. | ||||
| CVE-2020-3285 | 1 Cisco | 1 Secure Firewall Threat Defense | 2026-08-11 | 5.8 Medium |
| A vulnerability in the Transport Layer Security version 1.3 (TLS 1.3) policy with URL category functionality for Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to bypass a configured TLS 1.3 policy to block traffic for a specific URL. The vulnerability is due to a logic error with Snort handling of the connection with the TLS 1.3 policy and URL category configuration. An attacker could exploit this vulnerability by sending crafted TLS 1.3 connections to an affected device. A successful exploit could allow the attacker to bypass the TLS 1.3 policy and access URLs that are outside the affected device and normally would be dropped. | ||||
| CVE-2022-20826 | 1 Cisco | 7 Adaptive Security Appliance Software, Secure Firewall 3105, Secure Firewall 3110 and 4 more | 2026-08-11 | 6.4 Medium |

This vulnerability is due to a logic error in the boot process. An attacker could exploit this vulnerability by injecting malicious code into a specific memory location during the boot process of an affected device. A successful exploit could allow the attacker to execute persistent code at boot time and break the chain of trust. | ||||
| CVE-2022-20943 | 1 Cisco | 3 Cyber Vision, Meraki Mx Security Appliance Firmware, Secure Firewall Threat Defense | 2026-08-11 | 5.8 Medium |
| Multiple vulnerabilities in the Server Message Block Version 2 (SMB2) processor of the Snort detection engine on multiple Cisco products could allow an unauthenticated, remote attacker to bypass the configured policies or cause a denial of service (DoS) condition on an affected device. These vulnerabilities are due to improper management of system resources when the Snort detection engine is processing SMB2 traffic. An attacker could exploit these vulnerabilities by sending a high rate of certain types of SMB2 packets through an affected device. A successful exploit could allow the attacker to trigger a reload of the Snort process, resulting in a DoS condition. Note: When the snort preserve-connection option is enabled for the Snort detection engine, a successful exploit could also allow the attacker to bypass the configured policies and deliver a malicious payload to the protected network. The snort preserve-connection setting is enabled by default. See the Details ["#details"] section of this advisory for more information. Note: Only products that have Snort 3 configured are affected. Products that are configured with Snort 2 are not affected. | ||||
