- erofs: fix metabuf leak in inode xattr initialization
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
erofs: fix metabuf leak in inode xattr initialization
commit bb88e8da0025 ("erofs: use meta buffers for xattr operations") converted xattr operations to use on-stack erofsbuf instances. erofsinitinodexattrs() uses such a metabuf while reading the inline xattr header and shared xattr id array.
Some error paths after erofsreadmetabuf() leave through out_unlock without dropping the metabuf, so the folio reference can leak.
Consolidate the cleanup at outunlock. erofsputmetabuf() is a no-op if no folio has been acquired, and this keeps all paths after taking EROFSIBLXATTR_BIT covered by a single cleanup site.
