In the Linux kernel, the following vulnerability has been resolved:
erofs: fix the out-of-bounds nameoff handling for trailing dirents
Currently we already have boundary-checks for nameoffs, but the trailing
dirents are special since the namelens are calculated with strnlen()
with unchecked nameoffs.
If a crafted EROFS has a trailing dirent with nameoff >= maxsize,
maxsize - nameoff can underflow, causing strnlen() to read past the
directory block.
nameoff0 should also be verified to be a multiple of
`sizeof(struct erofs_dirent)` as well [1].
