1) Memory leak (CVE-ID: CVE-2026-68244)

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to a memory leak in the i915 GEM proto context creation extension handling when processing user extensions after a successful BALANCE/PARALLEL_SUBMIT extension. A local user can submit crafted context creation extensions to cause a denial of service.

The issue occurs when an error is triggered while processing a subsequent user extension after BALANCE/PARALLEL_SUBMIT has already succeeded.
