Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: apparmor: fix invalid deref of rawdata
when export_binary is unset If the export_binary parameter is disabled on runtime, profiles that were
loaded before that will still have their rawdata stored in apparmorfs, with a symbolic link to the rawdata
on the policy directory. When one of those profiles are replaced, the rawdata is set to NULL, but when
trying to resolve the symbolic links to rawdata for that profile, it will try to dereference
profile->rawdata->name when profile->rawdata is now NULL causing an oops. Fix it by checking if rawdata is
set. [ 168.653080] BUG: kernel NULL pointer dereference, address: 0000000000000088 [ 168.657420] #PF:
