Security Bulletin

This security bulletin contains information about 15 vulnerabilities.

1) 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.

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) Use of uninitialized resource

EUVDB-ID: #VU63352

Risk: Low

CVSSv3.1: 5.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-20008

CWE-ID: CWE-908 - Use of Uninitialized Resource

Exploit availability: No

Description

The vulnerability allows a local application to bypass certain security restrictions.

The vulnerability exists due to usage of uninitialized resources within the mmc_blk_read_single() function in block.c. A local application can obtain potentially sensitive information from memory when reading from an SD card that triggers errors.

Mitigation

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

3) 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.

4) Use-after-free

EUVDB-ID: #VU66396

Risk: Low

CVSSv3.1: 7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]

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.

Mitigation

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

9) Use-after-free

EUVDB-ID: #VU68422

Risk: Low

CVSSv3.1: 2.2 [CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-41222

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

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

The vulnerability exists due to a use-after-free error caused by a stale TLB in mm/mremap.c, because an rmap lock is not held during a PUD move. A local user can gain access to sensitive information.

Mitigation

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

10) Buffer overflow

EUVDB-ID: #VU68311

Risk: High

CVSSv3.1: 7.7 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-41674

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when processing WLAN frames within the ieee80211_bss_info_update() function in net/mac80211/scan.c in Linux kernel. A remote attacker on the local network can send specially crafted WLAN frames to the affected system, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

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

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.

15) Buffer overflow

EUVDB-ID: #VU68316

Risk: High

CVSSv3.1: 7.7 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-42721

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a list management error in the mac80211 stack in the Linux kernel when handling BSS. A remote attacker on the local network can send specially crafted WLAN frames to the system, trigger linked list corruption and execute arbitrary code.

Mitigation

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