{"apiVersion":"1.0","identifier":"CVE-2026-75900","description":"An out-of-bounds read vulnerability was found in swtpm-s SWTPM_NVRAM_CheckHeader() function. The entry guard checks the buffer length against sizeof(bh), where bh is a pointer, instead of sizeof(*bh), the actual struct size. This allows an undersized buffer to pass validation, causing a 2-byte heap overread on 64-bit systems (6 bytes on 32-bit) when accessing the totlen field. This may cause daemon termination on some platforms and leaks heap data to the log.","publishedAt":"2026-08-19T08:17:14","lastModifiedAt":"2026-08-21T20:16:42","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-75900","cvssScore":6.1,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:H","epssProbability":0.00111,"riskScore":0.62,"affectedProduct":"swtpm","affectedVersions":"unknown","vulnerabilityType":"Other","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-75900","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-75900","en":"https://www.redsauce.net/en/cves/CVE-2026-75900","fr":"https://www.redsauce.net/fr/cves/CVE-2026-75900","pt":"https://www.redsauce.net/pt/cves/CVE-2026-75900","de":"https://www.redsauce.net/de/cves/CVE-2026-75900","sk":"https://www.redsauce.net/sk/cves/CVE-2026-75900","el":"https://www.redsauce.net/el/cves/CVE-2026-75900"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-75900"}}
