A heap-based buffer overflow vulnerability was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip driver.
Noroxi assessment
Priority: Plan (action score 42/100)
- 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: 8.6% (FIRST EPSS); higher than 95.1% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: linux (Debian:12) 5.4.19-1; linux (Debian:8) 3.16.81-1; linux-4.9 (Debian:8) 4.9.210-1~deb8u1.
- Severity is disputed: the assigning authority (CNA) scores it 7.8, NVD 9.8.
- Mentioned 2 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Add it to your regular patch cycle. Upgrade to linux (Debian:12) 5.4.19-1; linux (Debian:8) 3.16.81-1; linux-4.9 (Debian:8) 4.9.210-1~deb8u1 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
A heap-based buffer overflow vulnerability was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip driver. A remote attacker could cause a denial of service (system crash) or, possibly execute arbitrary code, when the lbs_ibss_join_existing function is called after a STA connects to an AP.
