Patch Radar priority: Routine. - Web page: https://patchblox.com/security/cve/CVE-2023-52732 - Priority: Routine - CVSS: 5.5 (Moderate) - EPSS: 0.0053 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Mar 11, 2023 - Vendor advisory: https://msrc.microsoft.com/update-guide/vulnerability/CVE-2023-52732 ## Description In the Linux kernel, the following vulnerability has been resolved: ceph: blocklist the kclient when receiving corrupted snap trace When received corrupted snap trace we don't know what exactly has happened in MDS side. And we shouldn't continue IOs and metadatas access to MDS, which may corrupt or get incorrect contents. This patch will just block all the further IO/MDS requests immediately and then evict the kclient itself. The reason why we still need to evict the kclient just after blocking all the further IOs is that the MDS could revoke the caps faster. ## Where it's fixed | Platform | Product | Fixed in | Fix | Released | |---|---|---|---|---| | Linux | bpftool amzn 2023 | 6.1.15-28.43.amzn2023 | [ALAS2023-2023-127](https://patchblox.com/security/data/fix/linux/alas2023-2023-127.md) | Mar 11, 2023 | | Linux | bpftool-debuginfo amzn 2023 | 6.1.15-28.43.amzn2023 | [ALAS2023-2023-127](https://patchblox.com/security/data/fix/linux/alas2023-2023-127.md) | Mar 11, 2023 | | Linux | kernel amzn 2023 | 6.1.15-28.43.amzn2023 | [ALAS2023-2023-127](https://patchblox.com/security/data/fix/linux/alas2023-2023-127.md) | Mar 11, 2023 | | Linux | kernel-debuginfo amzn 2023 | 6.1.15-28.43.amzn2023 | [ALAS2023-2023-127](https://patchblox.com/security/data/fix/linux/alas2023-2023-127.md) | Mar 11, 2023 | | Linux | kernel-debuginfo-common-aarch64 amzn 2023 | 6.1.15-28.43.amzn2023 | [ALAS2023-2023-127](https://patchblox.com/security/data/fix/linux/alas2023-2023-127.md) | Mar 11, 2023 | | Linux | kernel-debuginfo-common-x86_64 amzn 2023 | 6.1.15-28.43.amzn2023 | [ALAS2023-2023-127](https://patchblox.com/security/data/fix/linux/alas2023-2023-127.md) | Mar 11, 2023 | | Linux | kernel-devel amzn 2023 | 6.1.15-28.43.amzn2023 | [ALAS2023-2023-127](https://patchblox.com/security/data/fix/linux/alas2023-2023-127.md) | Mar 11, 2023 | | Linux | kernel-headers amzn 2023 | 6.1.15-28.43.amzn2023 | [ALAS2023-2023-127](https://patchblox.com/security/data/fix/linux/alas2023-2023-127.md) | Mar 11, 2023 | | Linux | kernel-libbpf amzn 2023 | 6.1.15-28.43.amzn2023 | [ALAS2023-2023-127](https://patchblox.com/security/data/fix/linux/alas2023-2023-127.md) | Mar 11, 2023 | | Linux | kernel-libbpf-devel amzn 2023 | 6.1.15-28.43.amzn2023 | [ALAS2023-2023-127](https://patchblox.com/security/data/fix/linux/alas2023-2023-127.md) | Mar 11, 2023 | | Linux | kernel-libbpf-static amzn 2023 | 6.1.15-28.43.amzn2023 | [ALAS2023-2023-127](https://patchblox.com/security/data/fix/linux/alas2023-2023-127.md) | Mar 11, 2023 | | Linux | kernel-livepatch-6.1.15-28.43 amzn 2023 | 1.0-0.amzn2023 | [ALAS2023-2023-127](https://patchblox.com/security/data/fix/linux/alas2023-2023-127.md) | Mar 11, 2023 | | Linux | kernel-tools amzn 2023 | 6.1.15-28.43.amzn2023 | [ALAS2023-2023-127](https://patchblox.com/security/data/fix/linux/alas2023-2023-127.md) | Mar 11, 2023 | | Linux | kernel-tools-debuginfo amzn 2023 | 6.1.15-28.43.amzn2023 | [ALAS2023-2023-127](https://patchblox.com/security/data/fix/linux/alas2023-2023-127.md) | Mar 11, 2023 | | Linux | kernel-tools-devel amzn 2023 | 6.1.15-28.43.amzn2023 | [ALAS2023-2023-127](https://patchblox.com/security/data/fix/linux/alas2023-2023-127.md) | Mar 11, 2023 | | Linux | linux Debian 12.15 (bookworm) | 6.1.15-1 | [DEBIAN-CVE-2023-52732](https://patchblox.com/security/data/fix/linux/debian-cve-2023-52732.md) | May 21, 2024 | | Linux | linux Debian 13.5 (trixie) | 6.1.15-1 | [DEBIAN-CVE-2023-52732](https://patchblox.com/security/data/fix/linux/debian-cve-2023-52732.md) | May 21, 2024 | | Linux | linux Debian 14 | 6.1.15-1 | [DEBIAN-CVE-2023-52732](https://patchblox.com/security/data/fix/linux/debian-cve-2023-52732.md) | May 21, 2024 | | Linux | perf amzn 2023 | 6.1.15-28.43.amzn2023 | [ALAS2023-2023-127](https://patchblox.com/security/data/fix/linux/alas2023-2023-127.md) | Mar 11, 2023 | | Linux | perf-debuginfo amzn 2023 | 6.1.15-28.43.amzn2023 | [ALAS2023-2023-127](https://patchblox.com/security/data/fix/linux/alas2023-2023-127.md) | Mar 11, 2023 | | Linux | python3-perf amzn 2023 | 6.1.15-28.43.amzn2023 | [ALAS2023-2023-127](https://patchblox.com/security/data/fix/linux/alas2023-2023-127.md) | Mar 11, 2023 | | Linux | python3-perf-debuginfo amzn 2023 | 6.1.15-28.43.amzn2023 | [ALAS2023-2023-127](https://patchblox.com/security/data/fix/linux/alas2023-2023-127.md) | Mar 11, 2023 | --- Data as of 2026-11-09T13:31:49Z UTC.
