AZL-113095 CVE-2026-123876 affecting package cri-o 1.30.1-1

A flaw was found in the default seccomp profile used by Podman via containers-common. Deny rules for AFVSOCK and NETLINKAUDIT 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...

cri-o: cri-o: Sandbox state poisoning via pod annotations may expose runtime socket

A trust-boundary flaw in CRI-O's sandbox state persistence allows attacker-influenced pod metadata to overwrite CRI-O's own reserved sandbox bookkeeping; once reloaded as trusted after a restart, a later container recreate in that sandbox can expose a host-side runtime-management resource inside...

AZL-111700 CVE-2026-116591 affecting package cri-o 1.30.1-1

compress provides various compression algorithms. Prior to 1.20.2, the zstd DecodeAll and streaming decoder paths can panic when a crafted two-block frame reaches huff0.ReadTable with an FSE normalized count of 32768 that readNCount stores in int16 as -32768. The wrapped count allows buildDtable ...

CVE-2026-104795

The insights-runtime-extractor runs as a privileged DaemonSet hostPID: true that scans container processes for runtime fingerprinting. When scanning a container, the coordinator: 1. forks a child process 2. setns into the target container's PID and mount namespaces 3. fchdir back to an orphaned F...

CVE-2026-104795

The insights-runtime-extractor DaemonSet is vulnerable to a container escape due to insufficient privilege dropping during runtime fingerprinting. The coordinator uses seteuid() to switch users, but it fails to change the real UID (ruid) or saved-set-UID , which remain at 0 . Furthermore, the sec...
