CVE-2023-52930: drm/i915: Fix potential bit_17 double-free

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 0.27% (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 0769f997a7b6d5cb8336db0b4ec3d2d311b8097c, 7057a8f126f14f14b040faecfa220fd27c6c2f85, b591abac78e25269b12e3d7170c99463f8c5cb02.

Low priority for now. Upgrade to Linux Linux 0769f997a7b6d5cb8336db0b4ec3d2d311b8097c, 7057a8f126f14f14b040faecfa220fd27c6c2f85, b591abac78e25269b12e3d7170c99463f8c5cb02 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: drm/i915: Fix potential bit_17 double-free A userspace with multiple threads racing I915_GEM_SET_TILING to set the tiling to I915_TILING_NONE could trigger a double free of the bit_17 bitmask. (Or conversely leak memory on the transition to tiled.) Move allocation/free'ing of the bitmask within the section protected by the obj lock. [tursulin: Correct fixes tag and added cc stable.] (cherry picked from commit 10e0cbaaf1104f449d695c80bcacf930dcd3c42e)
