{"id":"AZL-113092","summary":"CVE-2026-123876 affecting package buildah 1.43.1-3","details":"A flaw was found in the default seccomp profile used by Podman via containers-common. Deny rules for AF_VSOCK and NETLINK_AUDIT compared socket arguments with unmasked 64-bit equality. Because the kernel truncates those int arguments to 32 bits, setting upper bits can bypass the deny rules.","modified":"2026-11-14T05:28:08Z","published":"2026-11-06T18:18:05Z","upstream":["CVE-2026-123876"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-123876"}],"affected":[{"package":{"name":"buildah","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/buildah"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"1.43.1-3"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-113092.json"}}],"schema_version":"1.9.2"}
