CVE-2026-72361: drm/xe/hw_engine: Fix double-free of managed BO in error path

Noroxi assessment

Priority: Monitor (action score 0/100)

  • 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: 0.20% (FIRST EPSS).
  • Fixed version: Linux Linux 1f6b44d555ecce61e249220f2ca4d75cdb90caf6, 23ee91355e31947595b86ebb9ef4664f20fd926d, 7ac3cae7a251d28e9079de07a991bd4eb2bb7fd8.

Low priority for now. Upgrade to Linux Linux 1f6b44d555ecce61e249220f2ca4d75cdb90caf6, 23ee91355e31947595b86ebb9ef4664f20fd926d, 7ac3cae7a251d28e9079de07a991bd4eb2bb7fd8 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: drm/xe/hw_engine: Fix double-free of managed BO in error path The error path in hw_engine_init() explicitly frees a BO allocated with xe_managed_bo_create_pin_map() via xe_bo_unpin_map_no_vm(). Since the managed BO already has a devm cleanup action registered, this causes a double-free when devm unwinds during probe failure. Remove the explicit free and let devm handle it, consistent with all other xe_managed_bo_create_pin_map() callers. (cherry picked from commit e459a3bdeb117be496d7f229e2ea1f6c9fe4080b)
