CVE-2024-50218

5.5 · MEDIUM
Published Nov 9, 2024 linux EPSS 0.27% (19th pctl)

Overview

CVE-2024-50218 is a medium-severity vulnerability affecting linux linux_kernel. It was published on November 9, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

ocfs2: pass u64 to ocfs2_truncate_inline maybe overflow

Syzbot reported a kernel BUG in ocfs2_truncate_inline. There are two

reasons for this: first, the parameter value passed is greater than

ocfs2_max_inline_data_with_xattr, second, the start and end parameters of

ocfs2_truncate_inline are "unsigned int".

So, we need to add a sanity check for byte_start and byte_len right before

ocfs2_truncate_inline() in ocfs2_remove_inode_range(), if they are greater

than ocfs2_max_inline_data_with_xattr return -EINVAL.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
