{"apiVersion":"1.0","identifier":"CVE-2026-71980","description":"Belledonne Communications bcg729 through 1.1.2 contains an out-of-bounds read vulnerability in the decodeSIDframe() function in src/cng.c that allows unauthenticated network-adjacent attackers to trigger a heap read beyond buffer boundaries by sending a zero-length comfort-noise RTP payload. A zero-length payload causes an integer underflow in the uint8_t filter order calculation, which wraps to 255 and is clamped to 10, causing the function to unconditionally read 11 bytes from a zero-byte buffer, resulting in media process termination or silent consumption of adjacent heap memory as reflection coefficients.","publishedAt":"2026-08-17T18:18:12","lastModifiedAt":"2026-08-17T19:16:38","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-71980","cvssScore":7.5,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","epssProbability":0.00339,"riskScore":0.77,"affectedProduct":"bcg729","affectedVersions":"<=1.1.2","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-71980","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-71980","en":"https://www.redsauce.net/en/cves/CVE-2026-71980","fr":"https://www.redsauce.net/fr/cves/CVE-2026-71980","pt":"https://www.redsauce.net/pt/cves/CVE-2026-71980","de":"https://www.redsauce.net/de/cves/CVE-2026-71980","sk":"https://www.redsauce.net/sk/cves/CVE-2026-71980","el":"https://www.redsauce.net/el/cves/CVE-2026-71980"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-71980"}}
