CVE-2019-9893
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.

Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.04%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
