Security Bulletin

This security bulletin contains information about 24 vulnerabilities.

1) Deadlock

EUVDB-ID: #VU73186

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-2022-4269

CWE-ID: CWE-833 - Deadlock

Exploit availability: No

Description

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

The vulnerability exists due to an error in the Linux kernel Traffic Control (TC) subsystem. A local user can use a specific network configuration (redirecting egress packets to ingress using TC action "mirred") to trigger a CPU soft lockup.

Mitigation

Update the affected package linux to the latest version.

2) Out-of-bounds read

EUVDB-ID: #VU78725

Risk: Low

CVSSv3.1: 6.2 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-48502

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

Exploit availability: No

Description

The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the ntfs_set_ea() function in fs/ntfs3/xattr.c in Linux kernel ntfs3 subsystem. A local user can trigger an out-of-bounds read error and read contents of memory on the system or crash the OS kernel.
