Description

This security bulletin contains information about 3 vulnerabilities.


1) Heap-based buffer overflow (CVE-ID: CVE-2019-14814)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: 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/E:U/U:Clear


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the mwifiex_update_vs_ie() function in the Marvell Wi-Fi chip driver in Linux kernel. A local user can run a specially crafted application to trigger a heap-based buffer overflow and execute arbitrary code on the system with elevated privileges.

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: 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/E:U/U:Clear


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the mwifiex_set_uap_rates() function in the Marvell Wi-Fi chip driver in Linux kernel. A local user can run a specially crafted application to trigger a heap-based buffer overflow and execute arbitrary code on the system with elevated privileges.
