Heap-based buffer overflow in Linux kernel - CVE-2019-10126

Published: September 3, 2019 / Updated: October 16, 2019


Vulnerability identifier: #VU20810
CSH Severity: Low
CVSS v4: 8.5 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

CWE-ID: CWE-122
Exploitation vector: Local access
Exploit availability: No public exploit available

Vulnerability details

The vulnerability allows a local user to perform a denial of service (DoS) condition or execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in the Marvell Wireless LAN device driver in "mwifiex_uap_parse_tail_ies" function in "drivers/net/wireless/marvell/mwifiex/ie.c". A local authenticated user can trigger heap-based buffer overflow and cause a denial of service (system crash) or possibly execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
