CVE-ID: CVE-2019-10126
CWE-ID:
CWE-122
Exploitation vector: Local
Exploit availability: No
Vulnerable software:
Linux kernel
Operating systems & Components /
Operating system
Vendor: Linux Foundation
Description
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.
