Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Double Free

EUVDB-ID: #VU63160

Risk: Low

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-2022-28388

CWE-ID: CWE-415 - Double Free

Exploit availability: No

Description

The vulnerability allows a local user to execute arbitrary code with elevated privileges.

The vulnerability exists due to boundary error in the usb_8dev_start_xmit in drivers/net/can/usb/usb_8dev.c. A local user can pass specially crafted data to the application, trigger double free error and execute arbitrary code with elevated privileges.

Mitigation

Install updates from vendor's repository.

3) Memory leak

EUVDB-ID: #VU63390

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2022-28356

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform DoS attack on the target system.

The vulnerability exists due memory leak in net/llc/af_llc.c component. A remote attacker can force the system to leak memory and perform denial of service attack.

Mitigation

Install updates from vendor's repository.
