CVSSv4.0: 5.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:H/E:U/U:Green]

CVE-ID: CVE-2022-42329

CWE-ID: CWE-399 - Resource Management Errors

Exploit availability: No

Description

The vulnerability allows an attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper management of internal resources. An attacker with access to the guest OS can trigger deadlock in Linux netback driver and perform a denial of service (DoS) attack of the host via the paravirtualized network interface.

Mitigation

Install updates from vendor's repository.

CVSSv4.0: 5.9 [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]

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.
