{"apiVersion":"1.0","identifier":"CVE-2026-53794","description":"rsync before 3.5.0 contains a logic error in --max-alloc handling that allows a sender or configuration setting --max-alloc=0 to disable allocation sanity checks entirely rather than enforcing a zero-byte cap. Attackers can exploit this flaw to cause the receiver to attempt unbounded memory allocations for file list and data structures, potentially exhausting available memory and causing a denial of service.","publishedAt":"2026-08-13T15:19:43","lastModifiedAt":"2026-08-13T16:18:06","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-53794","cvssScore":5.3,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","epssProbability":0.00372,"riskScore":0.55,"affectedProduct":"rsync","affectedVersions":"<3.5.0","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-53794","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-53794","en":"https://www.redsauce.net/en/cves/CVE-2026-53794","fr":"https://www.redsauce.net/fr/cves/CVE-2026-53794","pt":"https://www.redsauce.net/pt/cves/CVE-2026-53794","de":"https://www.redsauce.net/de/cves/CVE-2026-53794","sk":"https://www.redsauce.net/sk/cves/CVE-2026-53794","el":"https://www.redsauce.net/el/cves/CVE-2026-53794"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-53794"}}
