{"id":"AZL-92154","summary":"CVE-2026-56288 affecting package patch for versions less than 2.7.6-10","details":"GNU patch is vulnerable to a NULL pointer dereference when processing a specially crafted unified-diff patch file. Improper handling of consecutive end-of-file newline markers can corrupt internal hunk (single block of changes in diff) data structures, causing the application to pass a NULL pointer to fwrite() during patch processing.\nAn attacker can trigger this condition with a malicious patch file, causing the utility to crash and resulting in a denial of service.\n\n\n\nThis issue has been fixed in the commit e6d6a4e021660679d7fc9150f981d4920f722313","modified":"2026-08-29T05:27:27Z","published":"2026-07-09T11:16:40Z","upstream":["CVE-2026-56288"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-56288"}],"affected":[{"package":{"name":"patch","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/patch"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.7.6-10"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-92154.json"}}],"schema_version":"1.9.0"}
