A table that advertises one optional argument and supplies only a recognized option name, for example &#34;cache_mode&#34;, reaches parse_cache_opts() with argc == 1. The parser consumes the name, decrements argc to zero, then calls dm_shift_arg() again for the value. dm_shift_arg() returns NULL when no arguments remain, and the following strcmp() dereferences that NULL pointer.</p> <p>Check that each recognized option has a value before consuming it. This keeps valid &#34;cache_mode writeback&#34; and &#34;data_crc true/false&#34; tables unchanged while making malformed tables fail during target construction with a precise missing-value error.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>dm-pcache: reject option groups without values</p> <p>The pcache target parses optional arguments as name/value pairs.
