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.

Affected configurations

• linux linux kernel (>= 2.6.24 < 4.19.323) • linux linux kernel (>= 4.20 < 5.4.285) • linux linux kernel (>= 5.5 < 5.10.229) • linux linux kernel (>= 5.11 < 5.15.171) • linux linux kernel (>= 5.16 < 6.1.116) • linux linux kernel (>= 6.2 < 6.6.60) • linux linux kernel (>= 6.7 < 6.11.7) • linux linux kernel 6.12
