CVE-2026-80713
Description
AI Translation Available
In the Linux kernel, the following vulnerability has been resolved:
io_uring: preserve task restrictions across exec
Per-task restrictions apply to all rings created by a task. Once
installed, they should not be dropped across exec.
For a task that has used io_uring, the exec cancellation path calls
__io_uring_free(). This frees both the task context and the per-task
restriction, so a ring created after exec is unrestricted.
Split task context cleanup into io_uring_free_tctx(), and use it from
the exec cancellation path. Keep __io_uring_free() for final task
cleanup, where both the context and restriction are released.
