Security Bulletin

This security bulletin contains information about 16 vulnerabilities.

1) Race condition

EUVDB-ID: #VU77324

Risk: Low

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

CVE-ID: CVE-2022-44033

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

Exploit availability: No

Description

The vulnerability allows an attacker to escalate privileges on the system.

The vulnerability exists due to a race condition in drivers/char/pcmcia/cm4040_cs.c in Linux kernel. An attacker with physical access to device can remove the PCMCIA device while calling open() to trigger a use-after-free error and execute arbitrary code on the system.

Mitigation

Install updates from vendor's repository.

11) Out-of-bounds read

EUVDB-ID: #VU81919

Risk: Low

CVSSv4.0: 1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-39194

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 within the XFRM subsystem in Linux kernel. A local user with CAP_NET_ADMIN capability can trigger an out-of-bounds read error and read contents of memory on the system.

Mitigation

Install updates from vendor's repository.

CVE-ID: CVE-2023-45871

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 within the IGB driver in drivers/net/ethernet/intel/igb/igb_main.c when handling frames larger than the MTU. A remote attacker can send specially crafted traffic to the 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

Install updates from vendor's repository.
