This can lead to an unexpected &#34;BUG: kernel NULL pointer dereference&#34; if the corresponding decompressor isn&#39;t built-in.</p> <p>Fix this by checking against `sbi-&gt;available_compr_algs` for each m_algorithmformat request. Incorrect !erofs_sb_has_compr_cfgs preset bitmap is now fixed together since it was harmless previously.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>erofs: fix inconsistent per-file compression format</p> <p>EROFS can select compression algorithms on a per-file basis, and each per-file compression algorithm needs to be marked in the on-disk superblock for initialization.</p> <p>However, syzkaller can generate inconsistent crafted images that use an unsupported algorithmtype for specific inodes, e.g. use MicroLZMA algorithmtype even it&#39;s not set in `sbi-&gt;available_compr_algs`.
