CVE-2026-80713

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the io uring subsystem where per-task restrictions are not preserved across an exec operation. When a task that has used io uring undergoes the exec cancellation path, the io uring free() function is called, which incorrectly releases both the task context and the per-task restrictions. This allows any ring created after the exec operation to remain unrestricted.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
