Detailsinfo

A vulnerability classified as problematic was found in Linux Kernel up to 6.6.84/6.12.20/6.13.8. Affected by this vulnerability is the function qaic_validate_req. The manipulation with an unknown input leads to a integer overflow vulnerability. The CWE definition for the vulnerability is CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. The impact remains unknown. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: accel/qaic: Fix integer overflow in qaic_validate_req() These are u64 variables that come from the user via qaic_attach_slice_bo_ioctl(). Use check_add_overflow() to ensure that the math doesn't have an integer wrapping bug.

The advisory is shared at git.kernel.org. This vulnerability is known as CVE-2025-22001 since 12/29/2024. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 02/16/2026).
