• reproducer:

$ toolbox create --release 41
$ toolbox enter fedora-toolbox-41

toolbox $ sudo dnf install python3-libselinux
toolbox $ python3
>>> import selinux
>>> selinux.matchpathcon("/dev", 16384)
Segmentation fault (core dumped)

• workaround:

$ sudo dnf install selinux-policy-targeted

• possible regression commit - https://github.com/SELinuxProject/selinux/commit/5876aca0484f3b45636ef6337f06b914a8769cb4
