{"id":"AZL-95786","summary":"CVE-2026-53792 affecting package rsync for versions less than 3.5.0-1","details":"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.","modified":"2026-08-30T05:26:50Z","published":"2026-08-13T15:19:43Z","upstream":["CVE-2026-53792"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53792"}],"affected":[{"package":{"name":"rsync","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/rsync"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.5.0-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-95786.json"}}],"schema_version":"1.9.0"}
