{"apiVersion":"1.0","identifier":"CVE-2026-53792","description":"rsync before 3.5.0 contains an out-of-bounds read vulnerability in the sender-side block matching logic that allows a malicious receiver to trigger memory access before the start of an allocated buffer by sending a crafted checksum block with a length of zero. Attackers can send a specially crafted checksum set containing a zero-length block to cause a negative offset calculation during delta computation, resulting in an out-of-bounds read of file data buffer memory on the sender side.","publishedAt":"2026-08-13T15:19:43","lastModifiedAt":"2026-08-14T16:16:56","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-53792","cvssScore":6.5,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","epssProbability":0.00311,"riskScore":0.67,"affectedProduct":"rsync","affectedVersions":"<3.5.0","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-53792","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-53792","en":"https://www.redsauce.net/en/cves/CVE-2026-53792","fr":"https://www.redsauce.net/fr/cves/CVE-2026-53792","pt":"https://www.redsauce.net/pt/cves/CVE-2026-53792","de":"https://www.redsauce.net/de/cves/CVE-2026-53792","sk":"https://www.redsauce.net/sk/cves/CVE-2026-53792","el":"https://www.redsauce.net/el/cves/CVE-2026-53792"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-53792"}}
