6) Out-of-bounds read

EUVDB-ID: #VU66591

Risk: Low

CVSSv3.1: 5.3 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-1462

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

Exploit availability: No

Description

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

The vulnerability exists due to a boundary condition within the the Linux kernel’s TeleTYpe subsystem caused by a race condition when using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory file. A local user can trigger an out-of-bounds read error and crash the system or read random kernel memory.

Mitigation

Update the affected package the Linux Kernel to the latest version.

8) Security features bypass

EUVDB-ID: #VU66592

Risk: Low

CVSSv3.1: 5.9 [CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-21505

CWE-ID: CWE-254 - Security Features

Exploit availability: No

Description

The vulnerability allows an attacker to bypass implemented security restrictions.

The vulnerability exists due to incorrect implementation of the IMA lockdown feature. If IMA appraisal is used with the "ima_appraise=log" boot param, lockdown can be defeated with kexec on any machine with Secure Boot. An attacker with physical access to device can bypass Secure Boot mechanism.

Mitigation

Update the affected package the Linux Kernel to the latest version.

13) Information disclosure

EUVDB-ID: #VU65346

Risk: Low

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

CVE-ID: CVE-2022-33740

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

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

The vulnerability exists due to Linux Block and Network PV device frontends don't zero memory regions before sharing them with the backend. A local user can gain unauthorized access to sensitive information on the system.

Mitigation

Update the affected package the Linux Kernel to the latest version.

CVE-ID: CVE-2022-33741

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

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

The vulnerability exists due to granularity of the grant table doesn't allow sharing less than a 4K page, leading to unrelated data residing in the same 4K page as data shared with a backend being accessible by such backend. A local user can gain unauthorized access to sensitive information on the system.

16) Input validation error

EUVDB-ID: #VU66476

Risk: Medium

CVSSv3.1: 6.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2022-36946

CWE-ID: CWE-20 - Improper input validation

Exploit availability: Yes

Description

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

The vulnerability exists due to insufficient validation of user-supplied input within the nfqnl_mangle() function in net/netfilter/nfnetlink_queue.c in the Linux kernel when processing IPv6 packets. A remote attacker can send specially crafted packets to the system and perform a denial of service (DoS) attack.

Mitigation

Update the affected package the Linux Kernel to the latest version.
