jfs: array-index-out-of-bounds fix in dtReadFirst
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: 0.25% (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 22dcbf7661c6ffc3247978c254dc40b833a0d429, 25f1e673ef61d6bf9a6022e27936785896d74948, 2eea5fda5556ef03defebf07b0a12fcd2c5210f4; 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 22dcbf7661c6ffc3247978c254dc40b833a0d429, 25f1e673ef61d6bf9a6022e27936785896d74948, 2eea5fda5556ef03defebf07b0a12fcd2c5210f4; 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.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
In the Linux kernel, the following vulnerability has been resolved: jfs: array-index-out-of-bounds fix in dtReadFirst The value of stbl can be sometimes out of bounds due to a bad filesystem. Added a check with appopriate return of error code in that case.
