MediumMetricsAV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N
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.
