A\ntable that advertises one optional argument and supplies only a\nrecognized option name, for example \"cache_mode\", reaches\nparse_cache_opts() with argc == 1.  The parser consumes the name,\ndecrements argc to zero, then calls dm_shift_arg() again for the value.\ndm_shift_arg() returns NULL when no arguments remain, and the following\nstrcmp() dereferences that NULL pointer.\n\nCheck that each recognized option has a value before consuming it.  This\nkeeps valid \"cache_mode writeback\" and \"data_crc true/false\" tables\nunchanged while making malformed tables fail during target construction\nwith a precise missing-value error.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/0cbe13fe540330d31e5273bbf8cbd66bc7c9cb5a","https://git.kernel.org/stable/c/1247615aadb74c89c1b2f01a6de7df9dab92ecb3","https://git.kernel.org/stable/c/d9c631e3fbd44246a2be781d26cfacbb9b8ec127"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72104","score":0.00206,"percentile":0.10722,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
