CVE-2025-22001

Local privilege escalation via wrapped slice bounds

Published Apr 3, 2025 · Updated Aug 5, 2026

Integer overflow in the Linux kernel qaic driver allows local users to gain kernel privileges through a crafted slice request. qaic_validate_req adds user-controlled offset and size values without detecting wraparound, allowing an invalid range to pass its total-size check. Exploitation requires local access to the AIC100 accelerator device; crafted DMA descriptors permit host-memory read or write and a kernel crash.
