Security Bulletin

This security bulletin contains information about 10 vulnerabilities.

1) Memory leak

EUVDB-ID: #VU69798

Risk: Low

CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-3543

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

Exploit availability: No

Description

The vulnerability allows a local user to perform a DoS attack.

The vulnerability exists due memory leak within the unix_sock_destructor/unix_release_sock() function in net/unix/af_unix.c. A local user can force the system to leak memory and perform denial of service attack.

Mitigation

Update the affected package linux to the latest version.

4) Buffer overflow

EUVDB-ID: #VU69803

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-2022-3628

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

CVE-ID: CVE-2022-41849

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

Exploit availability: No

Description

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

The vulnerability exists due to a race condition in the drivers/video/fbdev/smscufx.c in the Linux kernel. An attacker with physical proximity to the system can remove the USB device while calling open(), cause a race condition between the ufx_ops_open and ufx_usb_disconnect and perform a denial of service (DoS) attack.

Mitigation

Update the affected package linux to the latest version.
