CVE-2026-43280

A flaw was found in the Linux kernel's drm/xe module. A local user can exploit this vulnerability by providing a malformed patindex value through the madvise IOCTL. This allows the xepatindexgetcohmode function to perform an out-of-bounds read from the xe-pat.table array, leading to information...
