CVE-2023-53683
Linux Kernel vulnerability analysis and mitigation

Overview

CVE-2023-53683 affects the Linux kernel's HFS+ filesystem implementation. The vulnerability was discovered when syzbot identified a WARNON() condition in the hfspluscat{read,write}inode() functions that could be triggered by crafted filesystem images containing bogus length values (NVD).

Technical details

The vulnerability exists in the HFS+ filesystem code where WARNON() conditions in hfspluscat{read,write}inode() functions can be triggered by maliciously crafted filesystem images that contain invalid length values. These conditions were determined not to be actual kernel bugs that would justify a kernel panic (NVD).

Impact

When exploited, this vulnerability could cause the kernel to issue warnings and potentially panic, though it was determined that these conditions should not actually result in kernel panics (NVD).

Mitigation and workarounds

The vulnerability has been resolved by removing the WARN_ON() conditions from the affected functions in the HFS+ filesystem code (NVD).
