Trivy's own label is CRITICAL. Rated critical by NVD, Photon OS. Rated lower by Red Hat (medium), Amazon (medium), Oracle (medium), Ubuntu (medium).

Description

libseccomp before 2.4.0 did not correctly generate 64-bit syscall argument comparisons using the arithmetic operators (LT, GT, LE, GE), which might able to lead to bypassing seccomp filters and potential privilege escalations.
