CVE-2026-23358

System crash via uninitialized slot-reset list access

Published Mar 25, 2026 · Updated Mar 25, 2026

Use of an uninitialized resource in Linux Kernel 6.16 through 6.18.16 and 6.19 through 6.19.6 allows local users to crash the system. The AMDGPU slot-reset error path consults an uninitialized hive pointer and can traverse an uninitialized reset-domain list when device recovery fails. Exploitation requires local low-privilege access, an AMD GPU using the affected driver, and a failed PCI slot reset; the reported impact is limited to availability.
