CVE-2026-89888Hinoki check available

Unspecified impact via freed endpoint reuse

Published Sep 16, 2026 · Updated Sep 16, 2026

Use-after-free in the Linux OV02A10 camera driver allows attackers to cause unspecified impact during device probing. The ov02a10_check_hwcfg() function releases the endpoint handle, then reads the ovti,mipi-clock-voltage property through that stale handle. Reachability requires the OV02A10 driver to probe a configured camera endpoint; the published record establishes no attacker-controlled path or concrete consequence beyond unsafe memory access.
