Last modified

CVE-2019-14896 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. 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.. EPSS estimates a 8.67% chance of exploitation in the next 30 days.
