Patch Radar priority: High. - Web page: https://patchblox.com/security/cve/CVE-2023-53732 - Priority: High - CVSS: n/a (important) - EPSS: 0.0020 - 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 NULL dereference in ni_write_inode Syzbot reports a NULL dereference in ni_write_inode. When creating a new inode, if allocation fails in mi_init function (called in mi_format_new function), mi->mrec is set to NULL. In the error path of this inode creation, mi->mrec is later dereferenced in ni_write_inode. Add a NULL check to prevent NULL dereference. ## 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-2023-53732](https://patchblox.com/security/data/fix/linux/debian-cve-2023-53732.md) | Oct 22, 2025 | | Linux | linux Debian 13.5 (trixie) | 6.3.7-1 | [DEBIAN-CVE-2023-53732](https://patchblox.com/security/data/fix/linux/debian-cve-2023-53732.md) | Oct 22, 2025 | | Linux | linux Debian 14 | 6.3.7-1 | [DEBIAN-CVE-2023-53732](https://patchblox.com/security/data/fix/linux/debian-cve-2023-53732.md) | Oct 22, 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 2026-11-08T13:06:02Z UTC.
