CVE-2026-23317

A flaw was found in the drm/vmwgfx component of the Linux kernel. Incorrect error handling in the vmwtranslateptr functions could cause them to return a success status even when an internal lookup operation failed. This could lead to the use of uninitialized pointers and out-of-bounds OOB memory...

CVE-2026-23304

A flaw was found in the Linux kernel. A local attacker could cause a null pointer dereference in the IPv6 routing subsystem when a slave device is being un-slaved from a Virtual Routing and Forwarding VRF instance. This vulnerability can lead to a system crash, resulting in a denial of service...
