- Summary
- CVE-2026-46078 affecting package kernel for versions less than 6.6.141.1-1
- Details
-
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].[1] https://sashiko.dev/#/patchset/20260416063511.3173774-1-hsiangkao%40linux.alibaba.com
