jfs: add sanity check for agwidth in dbMount

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.19% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 722e72f7f9c69fcb3ab7988c2471feff7a4c8de1, a065cec230aa807c18828a3eee82f1c8592c2adf, a260bf14cd347878f01f70739ba829442a474a16; azl3 kernel 6.6.85.1-4 on Azure Linux 3.0 6.6.92.2-1; azl3 kernel 6.6.92.2-1 on Azure Linux 3.0 6.6.92.2-1.

Low priority for now. Upgrade to Linux Linux 722e72f7f9c69fcb3ab7988c2471feff7a4c8de1, a065cec230aa807c18828a3eee82f1c8592c2adf, a260bf14cd347878f01f70739ba829442a474a16; azl3 kernel 6.6.85.1-4 on Azure Linux 3.0 6.6.92.2-1; azl3 kernel 6.6.92.2-1 on Azure Linux 3.0 6.6.92.2-1 or later.
