{"apiVersion":"1.0","identifier":"CVE-2026-68479","description":"In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btrtl: validate firmware patch bounds rtlbt_parse_firmware() copies patch_length - 4 bytes before appending the firmware version. A malformed firmware patch shorter than the version field can make this subtraction underflow and turn the copy into an oversized read and write during Bluetooth setup. The existing patch_offset + patch_length check can also wrap on 32-bit architectures. Validate the patch length and range without arithmetic overflow before allocating or copying the patch.","publishedAt":"2026-08-15T06:20:51","lastModifiedAt":"2026-08-17T06:17:57","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-68479","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00164,"riskScore":0.79,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-68479","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-68479","en":"https://www.redsauce.net/en/cves/CVE-2026-68479","fr":"https://www.redsauce.net/fr/cves/CVE-2026-68479","pt":"https://www.redsauce.net/pt/cves/CVE-2026-68479","de":"https://www.redsauce.net/de/cves/CVE-2026-68479","sk":"https://www.redsauce.net/sk/cves/CVE-2026-68479","el":"https://www.redsauce.net/el/cves/CVE-2026-68479"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-68479"}}
