In particular uncommon use cases a crafted filter program can cause the interpreter to try reading the OS process memory in the 32GiB around the buffer on 64-bit architectures and in the entire address space on 32-bit architectures.","modified":"2026-09-07T05:28:29Z","published":"2026-09-05T19:16:55Z","upstream":["CVE-2026-31912"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-31912"}],"affected":[{"package":{"name":"libpcap","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/libpcap"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"1.10.6-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-99741.json"}}],"schema_version":"1.9.0"}
