Upgrade SLES:15.1 libseccomp2-32bit to version 2.4.1-3.3.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libseccomp2-32bit package and not the libseccomp2-32bit package as distributed by SLES.
See How to fix? for SLES:15.1 relevant fixed versions and status.
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.
