CVE-2023-54272 is fixed in 22 products on 1 platform, first by ALAS2023-2024-784, released December 5, 2024. It is not reported as exploited. Patch Radar priority: High. - Web page: https://patchblox.com/security/cve/CVE-2023-54272 - Priority: High - CVSS: n/a (important) - EPSS: 0.0021 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Dec 5, 2024 ## Description In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fix a possible null-pointer dereference in ni_clear() In a previous commit c1006bd13146, ni->mi.mrec in ni_write_inode() could be NULL, and thus a NULL check is added for this variable. However, in the same call stack, ni->mi.mrec can be also dereferenced in ni_clear(): ntfs_evict_inode(inode) ni_write_inode(inode, ...) ni = ntfs_i(inode); is_rec_inuse(ni->mi.mrec) -> Add a NULL check by previous commit ni_clear(ntfs_i(inode)) is_rec_inuse(ni->mi.mrec) -> No check Thus, a possible null-pointer dereference may exist in ni_clear(). To fix it, a NULL check is added in this function. ## Where it's fixed | Platform | Product | Fixed in | Fix | Released | |---|---|---|---|---| | Linux | bpftool amzn 2023 | 6.1.82-99.168.amzn2023 | [ALAS2023-2024-784](https://patchblox.com/security/data/fix/linux/alas2023-2024-784.md) | Dec 5, 2024 | | Linux | bpftool-debuginfo amzn 2023 | 6.1.82-99.168.amzn2023 | [ALAS2023-2024-784](https://patchblox.com/security/data/fix/linux/alas2023-2024-784.md) | Dec 5, 2024 | | Linux | kernel amzn 2023 | 6.1.82-99.168.amzn2023 | [ALAS2023-2024-784](https://patchblox.com/security/data/fix/linux/alas2023-2024-784.md) | Dec 5, 2024 | | Linux | kernel-debuginfo amzn 2023 | 6.1.82-99.168.amzn2023 | [ALAS2023-2024-784](https://patchblox.com/security/data/fix/linux/alas2023-2024-784.md) | Dec 5, 2024 | | Linux | kernel-debuginfo-common-aarch64 amzn 2023 | 6.1.82-99.168.amzn2023 | [ALAS2023-2024-784](https://patchblox.com/security/data/fix/linux/alas2023-2024-784.md) | Dec 5, 2024 | | Linux | kernel-debuginfo-common-x86_64 amzn 2023 | 6.1.82-99.168.amzn2023 | [ALAS2023-2024-784](https://patchblox.com/security/data/fix/linux/alas2023-2024-784.md) | Dec 5, 2024 | | Linux | kernel-devel amzn 2023 | 6.1.82-99.168.amzn2023 | [ALAS2023-2024-784](https://patchblox.com/security/data/fix/linux/alas2023-2024-784.md) | Dec 5, 2024 | | Linux | kernel-headers amzn 2023 | 6.1.82-99.168.amzn2023 | [ALAS2023-2024-784](https://patchblox.com/security/data/fix/linux/alas2023-2024-784.md) | Dec 5, 2024 | | Linux | kernel-libbpf amzn 2023 | 6.1.82-99.168.amzn2023 | [ALAS2023-2024-784](https://patchblox.com/security/data/fix/linux/alas2023-2024-784.md) | Dec 5, 2024 | | Linux | kernel-libbpf-devel amzn 2023 | 6.1.82-99.168.amzn2023 | [ALAS2023-2024-784](https://patchblox.com/security/data/fix/linux/alas2023-2024-784.md) | Dec 5, 2024 | | Linux | kernel-libbpf-static amzn 2023 | 6.1.82-99.168.amzn2023 | [ALAS2023-2024-784](https://patchblox.com/security/data/fix/linux/alas2023-2024-784.md) | Dec 5, 2024 | | Linux | kernel-livepatch-6.1.82-99.168 amzn 2023 | 1.0-0.amzn2023 | [ALAS2023-2024-784](https://patchblox.com/security/data/fix/linux/alas2023-2024-784.md) | Dec 5, 2024 | | Linux | kernel-modules-extra amzn 2023 | 6.1.82-99.168.amzn2023 | [ALAS2023-2024-784](https://patchblox.com/security/data/fix/linux/alas2023-2024-784.md) | Dec 5, 2024 | | Linux | kernel-modules-extra-common amzn 2023 | 6.1.82-99.168.amzn2023 | [ALAS2023-2024-784](https://patchblox.com/security/data/fix/linux/alas2023-2024-784.md) | Dec 5, 2024 | | Linux | kernel-tools amzn 2023 | 6.1.82-99.168.amzn2023 | [ALAS2023-2024-784](https://patchblox.com/security/data/fix/linux/alas2023-2024-784.md) | Dec 5, 2024 | | Linux | kernel-tools-debuginfo amzn 2023 | 6.1.82-99.168.amzn2023 | [ALAS2023-2024-784](https://patchblox.com/security/data/fix/linux/alas2023-2024-784.md) | Dec 5, 2024 | | Linux | kernel-tools-devel amzn 2023 | 6.1.82-99.168.amzn2023 | [ALAS2023-2024-784](https://patchblox.com/security/data/fix/linux/alas2023-2024-784.md) | Dec 5, 2024 | | Linux | linux Debian 12.15 (bookworm) | 6.1.82-1 | [DEBIAN-CVE-2023-54272](https://patchblox.com/security/data/fix/linux/debian-cve-2023-54272.md) | Dec 30, 2025 | | Linux | linux Debian 13.5 (trixie) | 6.3.7-1 | [DEBIAN-CVE-2023-54272](https://patchblox.com/security/data/fix/linux/debian-cve-2023-54272.md) | Dec 30, 2025 | | Linux | linux Debian 14 | 6.3.7-1 | [DEBIAN-CVE-2023-54272](https://patchblox.com/security/data/fix/linux/debian-cve-2023-54272.md) | Dec 30, 2025 | | Linux | perf amzn 2023 | 6.1.82-99.168.amzn2023 | [ALAS2023-2024-784](https://patchblox.com/security/data/fix/linux/alas2023-2024-784.md) | Dec 5, 2024 | | Linux | perf-debuginfo amzn 2023 | 6.1.82-99.168.amzn2023 | [ALAS2023-2024-784](https://patchblox.com/security/data/fix/linux/alas2023-2024-784.md) | Dec 5, 2024 | | Linux | python3-perf amzn 2023 | 6.1.82-99.168.amzn2023 | [ALAS2023-2024-784](https://patchblox.com/security/data/fix/linux/alas2023-2024-784.md) | Dec 5, 2024 | | Linux | python3-perf-debuginfo amzn 2023 | 6.1.82-99.168.amzn2023 | [ALAS2023-2024-784](https://patchblox.com/security/data/fix/linux/alas2023-2024-784.md) | Dec 5, 2024 | --- Data as of 2026-11-09T01:18:40Z UTC.
