What to do
AI-suggested
A fix has been implemented in the Linux kernel to ensure the madvise VMA array is freed on all error paths after allocation. Users should apply the official kernel updates that include this patch. Since this is a kernel-level fix, upgrading to a patched kernel version is the recommended remediation.
Description
A vulnerability in the Linux kernel's drm/xe component was resolved that caused a memory leak when the L2 flush validation failed during the xe_vm_madvise_ioctl() operation. Specifically, the madvise VMA array allocated by get_vmas() was not freed on certain error paths, leading to a resource leak. The fix ensures that the array is properly freed on all error paths after allocation.
