CVE-2026-123876Podman: containers-common: containers-common: default seccomp af_vsock/netlink_audit deny rules bypassable via 32-bit truncation

Red Hat Red Hat Enterprise Linux 10; Red Hat Red Hat Enterprise Linux 8; Red Hat Red Hat Enterprise Linux 9; Red Hat Red Hat Hardened Images Veröffentlicht: (vor 5 Tagen)

Beschreibung

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.

Schwachstellentyp (CWE): CWE-184
