NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-5_14_21-150400_24_122-default package and not the kernel-livepatch-5_14_21-150400_24_122-default package as distributed by SLES. See How to fix? for SLES:15.4 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

io_uring/af_unix: disable sending io_uring over sockets

File reference cycles have caused lots of problems for io_uring in the past, and it still doesn't work exactly right and races with unix_stream_read_generic(). The safest fix would be to completely disallow sending io_uring files via sockets via SCM_RIGHT, so there are no possible cycles invloving registered files and thus rendering SCM accounting on the io_uring side unnecessary.
