Description Mikhail 2024-05-17 15:37:04 UTC
Description of problem:
SELinux is preventing /usr/bin/bash from map_read, map_write access on the bpf /lib64/ld-linux-x86-64.so.2.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that bash should be allowed map_read map_write access on the ld-linux-x86-64.so.2 bpf by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'selinux-autorel' --raw | audit2allow -M my-selinuxautorel
# semodule -X 300 -i my-selinuxautorel.pp
