CVE-2023-52601: jfs: fix 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 2037cb9d95f1741885f7daf50e8a028c4ade5317, 2e16a1389b5a7983b45cb2aa20b0e3f0ee364d6c, 3d3898b4d72c677d47fe3cb554449f2df5c12555.
  • Mentioned 2 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 2037cb9d95f1741885f7daf50e8a028c4ade5317, 2e16a1389b5a7983b45cb2aa20b0e3f0ee364d6c, 3d3898b4d72c677d47fe3cb554449f2df5c12555 or later.

In the Linux kernel, the following vulnerability has been resolved: jfs: fix array-index-out-of-bounds in dbAdjTree Currently there is a bound check missing in the dbAdjTree while accessing the dmt_stree. To add the required check added the bool is_ctl which is required to determine the size as suggest in the following commit. https://lore.kernel.org/linux-kernel-mentees/f9475918-2186-49b8-b801-6f0f9e75f4fa@oracle.com/
