Security Bulletin

This security bulletin contains information about 13 vulnerabilities.

1) Information exposure through microarchitectural state after transient execution

EUVDB-ID: #VU79262

Risk: Medium

CVSSv4.0: 2.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:N/E:U/U:Green]

CVE-ID: CVE-2022-40982

CWE-ID: CWE-1342 - Information Exposure through Microarchitectural State after Transient Execution

Exploit availability: No

Description

The vulnerability allows a malicious guest to escalate privileges on the system.

The vulnerability exists due to the way data is shared between threads whereby the AVX GATHER instructions on Intel processors can forward the content of stale vector registers to dependent instructions. A malicious guest can infer data from different contexts on the same core and execute arbitrary code with elevated privileges.

Mitigation

Install updates from vendor's repository.

10) Use-after-free

EUVDB-ID: #VU80587

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-2023-4207

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 the cls_fw component in Linux kernel packet scheduler. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.

Mitigation

Install updates from vendor's repository.

13) Race condition

EUVDB-ID: #VU83479

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-2023-4732

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

Exploit availability: No

Description

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

The vulnerability exists due to a race condition caused by a BUG statement referencing pmd_t x within the pfn_swap_entry_to_page () function. A local user can exploit the race and crash the kernel.
