CVE-2024-50218

CVE Details

Release Date:

2024-11-09

Description

In the Linux kernel, the following vulnerability has been resolved:\nocfs2: pass u64 to ocfs2_truncate_inline maybe overflow\nSyzbot reported a kernel BUG in ocfs2_truncate_inline. There are two\nreasons for this: first, the parameter value passed is greater than\nocfs2_max_inline_data_with_xattr, second, the start and end parameters of\nocfs2_truncate_inline are 'unsigned int'.\nSo, we need to add a sanity check for byte_start and byte_len right before\nocfs2_truncate_inline() in ocfs2_remove_inode_range(), if they are greater\nthan ocfs2_max_inline_data_with_xattr return -EINVAL.
