Security Bulletin

This security bulletin contains information about 21 vulnerabilities.

1) Use-after-free

EUVDB-ID: #VU28418

Risk: Low

CVSSv3.1: 6.4 [CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-19377

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a local non-authenticated attacker to execute arbitrary code.

In the Linux kernel 5.0.21, mounting a crafted btrfs filesystem image, performing some operations, and unmounting can lead to a use-after-free in btrfs_queue_work in fs/btrfs/async-thread.c.

Mitigation

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

2) Protection Mechanism Failure

EUVDB-ID: #VU54455

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-2020-26541

CWE-ID: CWE-693 - Protection Mechanism Failure

Exploit availability: No

Description

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

The Linux kernel through 5.8.13 does not properly enforce the Secure Boot Forbidden Signature Database (aka dbx) protection mechanism. This affects certs/blacklist.c and certs/system_keyring.c. A local user can escalate privileges on the system.

Mitigation

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

EUVDB-ID: #VU64263

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-2022-1974

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

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

The vulnerability exists due to a use-after-free error in the Linux kernel's NFC core functionality due to a race condition between kobject creation and delete. A local attacker with CAP_NET_ADMIN privilege can leak kernel information and escalate privileges on the system.

Mitigation

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

CVSSv3.1: 2.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-33981

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

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

The vulnerability exists due to a use-after-free error in drivers/block/floppy.c in the Linux kernel when deallocating raw_cmd in the raw_cmd_ioctl function(). A local user can trigger use-after-free and perform denial of service attack.

Mitigation

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