VUL-0: kernel-source-azure,kernel-source-rt,kernel-source: kernel: use-after-free in io_uring feature
Last modified: 2021-02-05 15:21:02 UTC
A use-after-free flaw was found in io_grab_files in fs/io_uring.c in io_uring I/O access. This flaw could allow a local attacker with a user privilege to crash the system at device IORING_OP_CLOSE operation where a file reference counter was not incremented while in use. This vulnerability could even lead to a kernel information leak problem.
