jfs: add a check to prevent array-index-out-of-bounds in dbAdjTree

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 0.24% (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 368a533152220b0a6f1142327d96c6b6361f3002, 3b5d21b56c3774bc84eab0a93aaac22a4475e2c4, 491487eeddccc4bb49f2e59d8c8f35bec89c15ca; azl3 kernel 6.6.64.2-9 on Azure Linux 3.0 6.6.76.1-1; cbl2 kernel 5.15.173.1-2 on CBL Mariner 2.0 5.15.176.3-1.

Low priority for now. Upgrade to Linux Linux 368a533152220b0a6f1142327d96c6b6361f3002, 3b5d21b56c3774bc84eab0a93aaac22a4475e2c4, 491487eeddccc4bb49f2e59d8c8f35bec89c15ca; azl3 kernel 6.6.64.2-9 on Azure Linux 3.0 6.6.76.1-1; cbl2 kernel 5.15.173.1-2 on CBL Mariner 2.0 5.15.176.3-1 or later.
