Vulnerability identifier: #VU24684

CSH Severity: Medium

CVSS v4: 8.7 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2019-14901

CWE-ID: CWE-787

Exploitation vector: Adjecent network

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input in Marvell WiFi chip driver within the "mwifiex_process_tdls_action_frame()" function in "marvell/mwifiex/tdls.c". A remote attacker on the local network can send a specially crafted network traffic, trigger out-of-bounds write and execute arbitrary code on the target system.
