CVE-2026-46046
Estado: ModificadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix missing brelse() in ext4_xattr_inode_dec_ref_all()
The commit c8e008b60492 ("ext4: ignore xattrs past end") introduced a refcount leak in when block_csum is false.
ext4_xattr_inode_dec_ref_all() calls ext4_get_inode_loc() to get iloc.bh, but never releases it with brelse().
