CVE-2026-123876 | BDVDB-2026-401314 Detail
Red HatRed Hat Enterprise Linux 10
Description#
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.
Impact#
Per CVSS v3.1: confidentiality impact low, integrity impact low, availability impact none. Attack vector: local.
