CVE-2026-72311

CVE-2026-72311 affects the Linux kernel DRM/XE path. The issue occurs in xe_vm_madvise_ioctl(), which allocates madvise_range.vmas in get_vmas(). When get_vmas() succeeds and later validation fails, control incorrectly jumps to madv_fini, skipping kfree(madvise_range.vmas) and leaking the VMA arr...

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-2026-68166

A flaw was found in the Linux kernel's userfaultfd mechanism. A local attacker with userfaultfd access could register on shadow stack Virtual Memory Areas VMAs. By discarding a page and injecting a page with chosen return addresses, an attacker could achieve arbitrary code execution. This...

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...
