Package: clamav-daemon
Version: 1.0.7+dfsg-1~deb12u1
Severity: normal
File: /usr/sbin/clamd
Dear Maintainers,
I noticed in my logcheck emails the below warning from auditd:
kernel: [15870.808220] audit: type=1400 audit(1736697075.886:31):
apparmor="DENIED" operation="open" profile="/usr/sbin/clamd"
name="/proc/1018/cgroup" pid=1018 comm="clamd" requested_mask="r"
denied_mask="r" fsuid=112 ouid=0
If I understand this correctly, the factory apparmor profile denies
that clam daemon to read its own "cgroup" file.
I assume that a line as follows has to be added to
/etc/apparmor.d/usr.sbin.clamd:
@{PROC}/[0-9]*/cgroup r,
I did it on my own machine, and it seems to have fixed the issue.
Many thanks in advance for looking into this issue.
Kind regards,
Ralf
