In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
io_uring: preserve task restrictions across exec<\/p>\n
Per-task restrictions apply to all rings created by a task. Once
\ninstalled, they should not be dropped across exec.<\/p>\n
For a task that has used io_uring, the exec cancellation path calls
\n__io_uring_free(). This frees both the task context and the per-task
\nrestriction, so a ring created after exec is unrestricted.<\/p>\n
Split task context cleanup into io_uring_free_tctx(), and use it from
\nthe exec cancellation path. Keep __io_uring_free() for final task
\ncleanup, where both the context and restriction are released.<\/p>\n","protected":false},"excerpt":{"rendered":"
