CVE-2025-37761: drm/xe: Fix an out-of-bounds shift when invalidating TLB

HighCVSS 7.1 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 28/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.21% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 28477f701b63922ff88e9fb13f5519c11cd48b86, 7bcfeddb36b77f9fe3b010bb0b282b7618420bba, e4715858f87b78ce58cfa03bbe140321edbbaf20.

Low priority for now. Upgrade to Linux Linux 28477f701b63922ff88e9fb13f5519c11cd48b86, 7bcfeddb36b77f9fe3b010bb0b282b7618420bba, e4715858f87b78ce58cfa03bbe140321edbbaf20 or later.

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Fix an out-of-bounds shift when invalidating TLB When the size of the range invalidated is larger than rounddown_pow_of_two(ULONG_MAX), The function macro roundup_pow_of_two(length) will hit an out-of-bounds shift [1]. Use a full TLB invalidation for such cases. v2: - Use a define for the range size limit over which we use a full TLB invalidation. (Lucas) - Use a better calculation of the limit.
