CVE-2024-53098

CVE-2024-53098 affects the Linux kernel DRM XE ufence path. The root cause is that access_ok() only checks for addr overflow and may also read the user-supplied address to catch invalid addresses, coupled with prefetching ufence addresses to detect bogus ones. The issue is remedied by a kernel fi...
