Description
This security bulletin contains information about 1 vulnerability.
1) Double free (CVE-ID: CVE-2026-64517)
CWE-ID: CWE-415 - Double Free
CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to double free in xe_gsc_init_post_hwconfig() in the xe_gsc driver component when handling a probe failure error path. A local user can trigger the vulnerable error path to cause a denial of service.
The issue occurs because a managed buffer object is freed explicitly even though a devm cleanup action is already registered.
