Security Bulletin

This security bulletin contains information about 26 vulnerabilities.

1) Code injection

EUVDB-ID: #VU67512

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-2016-3695

CWE-ID: CWE-74 - Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')

Exploit availability: No

Description

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

The vulnerability exists within the einj_error_inject() function in drivers/acpi/apei/einj.c in the Linux kernel, which allows local users to simulate hardware errors. A local user can cause a denial of service by leveraging failure to disable APEI error injection through EINJ when securelevel is set.

Mitigation

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

2) Use-after-free

EUVDB-ID: #VU68424

Risk: Low

CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-16119

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 caused by the reuse of a DCCP socket with an attached dccps_hc_tx_ccid object as a listener. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.

Mitigation

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

6) Use-after-free

EUVDB-ID: #VU63838

Risk: Low

CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-4203

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 in sock_getsockopt() function in net/core/sock.c due to SO_PEERCRED and SO_PEERGROUPS race with listen() function (and connect() function) in the Linux kernel. A local user can exploit the use-after-free error and crash the system or escalate privileges on the system.

Mitigation

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

9) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU66810

Risk: Low

CVSSv3.1: 5.8 [CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-2503

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

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

The vulnerability exists due to the way dm-verity is used to restrict module/firmware loads to trusted root filesystem in LoadPin builds. Device-mapper table reloads currently allow users with root privileges to switch out the target with an equivalent dm-linear target and bypass verification till reboot. This allows root to bypass LoadPin and can be used to load untrusted and unverified kernel modules and firmware, which implies arbitrary kernel execution and persistence for peripherals that do not verify firmware updates.

Mitigation

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

CVE-ID: CVE-2022-2586

CWE-ID: CWE-416 - Use After Free

Exploit availability: Yes

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 netfilter subsystem implementation in Linux kernel when preventing one nft object from referencing an nft set in another nft table. A local user can trigger a use-after-free error and execute arbitrary code on the system with elevated privileges.

25) Race condition

EUVDB-ID: #VU68339

Risk: Low

CVSSv3.1: 3.8 [CVSS:3.1/AV:P/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-41848

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 in the drivers/char/pcmcia/synclink_cs.c in the Linux kernel. An attacker with physical proximity to the affected system can remove a PCMCIA device while calling ioctl, cause a race condition between mgslpc_ioctl and mgslpc_detach and perform a denial of service (DoS) attack.

Mitigation

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