{"id":"AZL-112679","summary":"CVE-2026-120830 affecting package libslirp 4.9.6-1","details":"A flaw was found in libslirp in icmp_forward_error(). When building an ICMP error response, the length of the quoted original IPv4 packet was taken from the IP header without clamping it to the actual buffer length. A truncated or malformed packet could cause an out-of-bounds heap read, leaking host memory into the ICMP error packet returned to a guest or container.","modified":"2026-11-05T14:17:04.865273913Z","published":"2026-11-03T00:17:18Z","upstream":["CVE-2026-120830"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-120830"}],"affected":[{"package":{"name":"libslirp","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/libslirp"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"4.9.6-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-112679.json"}}],"schema_version":"1.9.2"}
