12) Out-of-bounds write

EUVDB-ID: #VU70625

Risk: Low

CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-47518

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

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

The vulnerability exists due to a boundary error when processing a number of channels in drivers/net/wireless/microchip/wilc1000/cfg80211.c in the WILC1000 wireless driver. A local user can trigger a heap-based buffer overflow when copying the list of operating channels from Wi-Fi management frames and execute arbitrary code with elevated privileges.

Mitigation

Install updates from vendor's repository.

CVE-ID: CVE-2022-47520

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary condition within the drivers/net/wireless/microchip/wilc1000/hif.c in the WILC1000 wireless driver. A local user can trigger an out-of-bounds read when parsing a Robust Security Network (RSN) information element from a Netlink packet and perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's repository.
