CVE-2026-43280

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Add bounds check on pat_index to prevent OOB kernel read in madvise When user provides a bogus pat_index value through the madvise IOCTL, the xe_pat_index_get_coh_mode() function performs an array access without validating bounds. This allows a malicious user to trigger an out-of-bounds kernel read from the xe->pat.table array. The vulnerability exists because the validation in madvise_args_are_sane() directly calls x
