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

ocfs2: strict bound check before memcmp in ocfs2_xattr_find_entry()

xattr in ocfs2 maybe ‘non-indexed’, which saved with additional space
requested. It’s better to check if the memory is out of bound before
memcmp, although this possibility mainly comes from crafted poisonous
images.
