Detailsinfo

A vulnerability has been found in Linux Kernel up to 6.11.6 and classified as problematic. Affected by this vulnerability is the function ocfs2_truncate_inline. The manipulation of the argument value with an unknown input leads to a data authenticity vulnerability. The CWE definition for the vulnerability is CWE-345. The product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data. The impact remains unknown. The summary by CVE is:

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.

The advisory is shared at git.kernel.org. This vulnerability is known as CVE-2024-50218 since 10/21/2024. Technical details are known, but no exploit is available.
