{"apiVersion":"1.0","identifier":"CVE-2026-72104","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.","publishedAt":"2026-08-15T06:21:24","lastModifiedAt":"2026-08-17T06:18:09","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72104","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00198,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72104","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72104","en":"https://www.redsauce.net/en/cves/CVE-2026-72104","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72104","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72104","de":"https://www.redsauce.net/de/cves/CVE-2026-72104","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72104","el":"https://www.redsauce.net/el/cves/CVE-2026-72104"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72104"}}
