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].
