| In fixInitiatingUserIfNecessary of CallIntentProcessor.java, there is a possible way to make an emergency call due to a logic error in the code. This could lead to local escalation with User execution privileges needed. User interaction is needed for exploitation. |
| xmlregexp in libxml2 before 2.15.4 has a NULL pointer dereference in xmlRegNewParserCtxt after a strdup failure, i.e., it does not calculate a string length after NULL checking. |
| Null pointer dereference in Windows Biometric Service allows an authorized attacker to elevate privileges locally. |
| In the Linux kernel, the following vulnerability has been resolved:
PCI: host-generic: Fix NULL pointer dereference on 32-bit CAM systems
On 32-bit systems the config space is too large to ioremap in one go, so
pci_ecam_create() maps each bus segment separately and relies on the
->add_bus callback (pci_ecam_add_bus) to populate the per-bus mapping in
cfg->winp[]. pci_ecam_map_bus() then uses that mapping as the base for
every config access.
The generic ECAM ops (pci_generic_ecam_ops) already provide the ->add_bus
and ->remove_bus callbacks, but the CAM (legacy) ops in pci-host-generic.c
do not. As a result, on a 32-bit host using "pci-host-cam-generic" the
per-bus mapping is never set up and the first config read dereferences a
NULL base, crashing during bus enumeration:
Unable to handle kernel NULL pointer dereference at virtual address 00000800

Fix this by giving the CAM ops the same ->add_bus/->remove_bus callbacks.
Since pci_ecam_add_bus() and pci_ecam_remove_bus() are static to ecam.c,
move the CAM ops definition there as pci_generic_cam_ops (mirroring
pci_generic_ecam_ops) and export it for pci-host-generic.c to reference.

| A flaw was found in 389 Directory Server. A missing NULL pointer check in the paged results handling of op_shared_search allows an unauthenticated remote attacker to crash the LDAP server by sending a crafted sequence of search requests using the USE_ONE_BACKEND control, resulting in denial of service. |
| IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to cause a denial of service due to a NULL pointer dereference. |
| NVIDIA DGX Spark contains a vulnerability in the system firmware, where a privileged attacker could be able to cause a NULL pointer dereference. A successful exploit of this vulnerability may lead to code execution, escalation of privileges, denial of service, information disclosure, and data tampering. |
| mrubyc through 4.0.0 contains a null pointer dereference vulnerability in the op_enter() handler in src/vm.c when processing untrusted bytecode. Attackers can craft malicious .mrb bytecode files with OP_ENTER instructions at the top level to crash the embedding application and cause denial of service. |
| SSH servers which use CertChecker as a public key callback without setting IsUserAuthority or IsHostAuthority could be caused to panic by a client presenting a certificate. CertChecker now returns an error instead of panicking when these callbacks are nil. |
| Null pointer dereference in Windows SMB Server Network Transport Driver (srvnet.sys) allows an unauthorized attacker to deny service over a network. |
| Null pointer dereference in Windows Routing and Remote Access Service (RRAS) allows an authorized attacker to deny service over a network. |
| Null pointer dereference in Windows Schannel allows an authorized attacker to deny service over a network. |
| Null pointer dereference in Windows IKE Extension allows an unauthorized attacker to deny service over a network. |
| Null pointer dereference in Windows Kerberos allows an unauthorized attacker to deny service over a network. |
| Null pointer dereference in Windows IKE Extension allows an unauthorized attacker to deny service over a network. |
| Null pointer dereference in Virtual Hard Disk (VHD) Miniport Driver allows an unauthorized attacker to deny service locally. |
| Null pointer dereference in Skype for Business allows an authorized attacker to deny service over a network. |
| Null pointer dereference in Active Directory Domain Services allows an authorized attacker to deny service over a network. |
