CVE-2024-41016:
Linux Kernel vulnerability analysis and mitigation
Overview
CVE-2024-41016 affects the Linux kernel's OCFS2 (Oracle Cluster File System 2) implementation. The vulnerability was discovered and disclosed on July 29, 2024, specifically in the ocfs2xattrfind_entry() function. The issue arises when handling non-indexed xattr entries that are saved with additional space requested (Kernel Git).
Technical details
The vulnerability exists in the ocfs2xattrfind_entry() function where there was insufficient boundary checking before performing a memcmp operation. When processing xattr entries that are 'non-indexed', the function failed to verify if the memory access would exceed the allocated bounds, potentially leading to out-of-bounds memory access (Kernel Git).
Impact
The vulnerability could be triggered by mounting a specially crafted poisonous filesystem image, potentially leading to memory corruption. This could result in system crashes or potential security implications when processing maliciously crafted OCFS2 filesystems (Ubuntu Security).
Mitigation and workarounds
The issue has been fixed in various Linux kernel versions across different distributions. Ubuntu has released patches for multiple versions: Ubuntu 24.04 LTS (6.8.0-54.56), Ubuntu 22.04 LTS (5.15.0-127.137), and Ubuntu 20.04 LTS (5.4.0-208.228). Users should update their systems to the patched versions (Ubuntu Security).
