Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Use-after-free

EUVDB-ID: #VU69759

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-2022-3424

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a use-after-free error within the gru_set_context_option(), gru_fault() and gru_handle_user_call_os() functions in Linux kernel. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.

Mitigation

Install updates from vendor's repository.

2) Improper access control

EUVDB-ID: #VU71541

Risk: Low

CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2022-4662

CWE-ID: CWE-284 - Improper Access Control

Exploit availability: No

Description

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

The vulnerability exists due to improper access restrictions in the Linux kernel USB core subsystem in the way user attaches usb device. A local user can perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's repository.

3) Use-after-free

EUVDB-ID: #VU70508

Risk: Low

CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2022-47946

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

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

The vulnerability exists due to a use-after-free error within the io_sqpoll_wait_sq() function in fs/io_uring.c. A remote attacker can crash the kernel by forking a process and then quickly terminating it.

Mitigation

Install updates from vendor's repository.
