Security Bulletin

This security bulletin contains information about 20 vulnerabilities.

1) Improper access control

EUVDB-ID: #VU63923

Risk: Low

CVSSv3.1: 3.9 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-4037

CWE-ID: CWE-284 - Improper Access Control

Exploit availability: No

Description

The vulnerability allows a local user to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to improper access restrictions in the fs/inode.c:inode_init_owner() function logic of the Linux kernel. A local user can create files for the XFS file-system with an unintended group ownership and with group execution and SGID permission bits set to bypass implemented security restrictions and gain unauthorized access to the application.

Mitigation

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

7) Memory leak

EUVDB-ID: #VU69756

Risk: Medium

CVSSv3.1: 4.6 [CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-3524

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform DoS attack on the target system.

The vulnerability exists due memory leak within the ipv6_renew_options() function when retrieving a new IPv6 address from a malicious DHCP server. A remote attacker can force the system to leak memory and perform denial of service attack.

Mitigation

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

11) Use-after-free

EUVDB-ID: #VU69708

Risk: Low

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-2022-3586

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 in the way the sch_sfb enqueue function used the socket buffer (SKB) cb field after the same SKB had been enqueued (and freed) into a child qdisc. A local user can perform a denial of service (DoS) attack.

Mitigation

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

13) NULL pointer dereference

EUVDB-ID: #VU69300

Risk: Low

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

CVE-ID: CVE-2022-3621

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in the nilfs2 filesystem driver within the nilfs_bmap_lookup_at_level() function in fs/nilfs2/inode.c in Linux kernel. A remote attacker can trick the victim into mounting a specially crafted image and perform a denial of service (DoS) attack.

Mitigation

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

18) Improper access control

EUVDB-ID: #VU67587

Risk: Low

CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-40768

CWE-ID: CWE-284 - Improper Access Control

Exploit availability: No

Description

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

The vulnerability exists due to improper access restrictions in the drivers/scsi/stex.c in the Linux kernel. A local user can obtain sensitive information from kernel memory because stex_queuecommand_lck lacks a memset for the PASSTHRU_CMD case.

Mitigation

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

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 mm/rmap.c in the Linux kernel, related to leaf anon_vma double reuse. A local user can trigger a use-after-free error and crash the kernel.

Mitigation

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

20) Out-of-bounds write

EUVDB-ID: #VU69296

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-2022-43750

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

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

The vulnerability exists due to a boundary error within the drivers/usb/mon/mon_bin.c in usbmon in the Linux kernel. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.

Mitigation

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