kernel: xen/privcmd: fix double free via VMA splitting

A flaw was found in the Linux kernel's xen/privcmd module. A local user could exploit this by performing a partial unmapping of a privcmd memory region. This action causes a Virtual Memory Area VMA to split, leading to duplicated internal memory pointers. As a result, the same memory can be freed...

CVE-2026-68265

A flaw was found in the Linux kernel. Specifically, within the drm/xe/vm module, an out-of-bounds access can occur when handling the DRMXECONSULTMEMADVISEPREFLOC region for a Buffer Object BO Virtual Memory Area VMA. This happens because a value of -1 is incorrectly used as an index into a memory...
