Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Input validation error

EUVDB-ID: #VU87772

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-2022-48619

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

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

The vulnerability exists due to insufficient validation of user-supplied input within the input_set_capability() function in drivers/input/input.c. A local user can crash the OS kernel.

Mitigation

Install updates from vendor's repository.

Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Improper Initialization

EUVDB-ID: #VU86579

Risk: Low

CVSSv3.1: 3.3 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-0340

CWE-ID: CWE-665 - Improper Initialization

Exploit availability: No

Description

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

The vulnerability exists due to improper initialization within the vhost_new_msg() function in drivers/vhost/vhost.c in the Linux kernel vhost driver. A local user can run a specially crafted application to gain access to sensitive kernel information.

Mitigation

Install updates from vendor's repository.

3) Improper locking

EUVDB-ID: #VU86245

Risk: Low

CVSSv3.1: 5.7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-0641

CWE-ID: CWE-667 - Improper Locking

Exploit availability: No

Description

The vulnerability allows a malicious guest to perform a denial of service attack (DoS) on the target system.

The vulnerability exists due to double-locking error within the tipc_crypto_key_revoke() function in net/tipc/crypto.c. A malicious guest can exploit this vulnerability to cause a deadlock, resulting in a denial of service.

Mitigation

Install updates from vendor's repository.
