Security Bulletin

This security bulletin contains information about 17 vulnerabilities.

1) Improper access control

EUVDB-ID: #VU63923

Risk: Low

CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

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.

CVSSv4.0: 4.8 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2022-3649

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error within the nilfs2 filesystem driver in nilfs_new_inode() function in fs/nilfs2/inode.c in Linux kernel. A remote attacker can trick the victim into mounting a specially crafted image, trigger a use-after-free error and execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.

Mitigation

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

17) Out-of-bounds write

EUVDB-ID: #VU69296

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-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.
