CVE-2026-93258

Unknown

Last modified

CVE-2026-93258 is a vulnerability of currently unknown severity. In the Linux kernel, the following vulnerability has been resolved: ocfs2: do not use make_bad_inode() in ocfs2_read_inode_block_full() This reverts commit 58b6fcd2ab34 ("ocfs2: mark inode bad upon validation failure during read"). Since 'make_bad_inode()' resets inode type to S_IFREG, doing this for directory inode during active VFS lookup is likely to confuse the latter, including VFS_BUG_ON_INODE() triggered in this case..
