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 packages:

8) Buffer overflow

EUVDB-ID: #VU83381

Risk: High

CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

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.

11) Stack-based buffer overflow

EUVDB-ID: #VU87901

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-2023-52628

CWE-ID: CWE-121 - Stack-based buffer overflow

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 nft_exthdr_sctp_eval(), nft_exthdr_tcp_eval(), and nft_exthdr_ipv6_eval() functions. A local user can pass specially crafted data to the system, trigger a stack-based buffer overflow and execute arbitrary code with elevated privileges.

Mitigation

12) NULL pointer dereference

EUVDB-ID: #VU84096

Risk: Low

CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2023-6176

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

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

The vulnerability exists due to a NULL pointer dereference error in the Linux kernel API for the cryptographic algorithm scatterwalk functionality in scatterwalk_copychunks(). A local user can send a malicious packet with specific socket configuration and crash the OS kernel.
