CVE-2026-72104
Overview
CVE-2026-72104 is a known-severity vulnerability. It was published on August 15, 2026.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
dm-pcache: reject option groups without values
The pcache target parses optional arguments as name/value pairs. A
table that advertises one optional argument and supplies only a
recognized option name, for example "cache_mode", 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.
Check that each recognized option has a value before consuming it. This
keeps valid "cache_mode writeback" and "data_crc true/false" tables
unchanged while making malformed tables fail during target construction
with a precise missing-value error.
