CVE-2026-80713

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