Date: Wed, 8 May 2024 20:37:34 +0100 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-cve-announce@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org> Subject: CVE-2023-52654: io_uring/af_unix: disable sending io_uring over sockets Description =========== 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. The Linux kernel CVE team has assigned CVE-2023-52654 to this issue. Affected and fixed versions =========================== Issue introduced in 5.4.220 with commit 04df9719df18 and fixed in 5.4.264 with commit 18824f592aad Issue introduced in 5.10.150 with commit c378c479c517 and fixed in 5.10.204 with commit 3fe1ea5f921b Issue introduced in 5.15.75 with commit 813d8fe5d303 and fixed in 5.15.143 with commit bcedd497b3b4 Issue introduced in 6.1 with commit 0091bfc81741 and fixed in 6.1.68 with commit f2f57f51b53b Issue introduced in 6.1 with commit 0091bfc81741 and fixed in 6.6.7 with commit 5a33d385eb36 Issue introduced in 6.1 with commit 0091bfc81741 and fixed in 6.7 with commit 705318a99a13 Issue introduced in 5.19.17 with commit b4293c01ee0d Issue introduced in 6.0.3 with commit 75e94c7e8859 Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2023-52654 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: io_uring/rsrc.h net/core/scm.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/18824f592aad4124d79751bbc1500ea86ac3ff29 https://git.kernel.org/stable/c/3fe1ea5f921bf5b71cbfdc4469fb96c05936610e https://git.kernel.org/stable/c/bcedd497b3b4a0be56f3adf7c7542720eced0792 https://git.kernel.org/stable/c/f2f57f51b53be153a522300454ddb3887722fb2c https://git.kernel.org/stable/c/5a33d385eb36991a91e3dddb189d8679e2aac2be https://git.kernel.org/stable/c/705318a99a138c29a512a72c3e0043b3cd7f55f4
