Kernel oops via sign-reversed dependency error
Published Apr 16, 2025 · Updated May 11, 2026
Denial of service in the Linux kernel 6.14 through 6.14.1 allows local users to trigger a kernel oops through an invalid MSM GPU dependency submit. The msm_parse_deps function negates the already-negative SUBMIT_ERROR(EINVAL) result, passes positive EINVAL to ERR_PTR, and thereby defeats the later IS_ERR check. Exploitation requires low-privileged local access to the MSM DRM submission path and interrupts the affected host without reported data disclosure or modification.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
