Security Bulletin

This security bulletin contains information about 12 vulnerabilities.

1) Out-of-bounds read

EUVDB-ID: #VU80795

Risk: Low

CVSSv4.0: 1.7 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-37453

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

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

The vulnerability exists due to a boundary condition within the read_descriptors() function in drivers/usb/core/sysfs.c. An attacker with physical access to the system can attach a malicious USB device, trigger an out-of-bounds read error and crash the kernel.

Mitigation

Update the affected package linux to the latest version.

No. We are not aware of malware exploiting this vulnerability.

2) Out-of-bounds read

EUVDB-ID: #VU80579

Risk: Low

CVSSv4.0: 4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-3773

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

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

The vulnerability exists due to a boundary condition in IP framework for transforming packets (XFRM subsystem). A local user with CAP_NET_ADMIN privileges can cause a 4 byte out-of-bounds read of XFRMA_MTIMER_THRESH when parsing netlink attributes and gain access to sensitive information.

Mitigation

Update the affected package linux to the latest version.

3) Out-of-bounds read

EUVDB-ID: #VU82659

Risk: Low

CVSSv4.0: 5.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-39189

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

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