3) Resource management error

EUVDB-ID: #VU80121

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-2023-3777

CWE-ID: CWE-399 - Resource Management Errors

4) Out-of-bounds read

EUVDB-ID: #VU84353

Risk: Medium

CVSSv3.1: 5.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-39197

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

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the Netfilter Connection Tracking (conntrack) in the Linux kernel in the nf_conntrack_dccp_packet() function in net/netfilter/nf_conntrack_proto_dccp.c. A remote attacker can send specially crafted DCCP packets to the system, trigger an out-of-bounds read error and read contents of memory on the system.

Mitigation

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

8) Buffer overflow

EUVDB-ID: #VU83381

Risk: High

CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

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

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

The vulnerability exists due to improper access checking in the #VC handler and instruction emulation of the SEV-ES emulation of MMIO accesses. A local user can gain arbitrary write access to kernel memory and execute arbitrary code with elevated privileges.

Mitigation

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

11) Input validation error

EUVDB-ID: #VU83440

Risk: Medium

CVSSv3.1: 5.9 [CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-5158

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a malicious guest to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input within the vringh_kiov_advance() function in drivers/vhost/vringh.c in the host side of a virtio ring. A malicious guest can crash the host OS via zero length descriptor.

14) Use-after-free

EUVDB-ID: #VU83905

Risk: Low

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

CVE-ID: CVE-2023-6039

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

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

The vulnerability exists due to a use-after-free error within the lan78xx_disconnect() function in drivers/net/usb/lan78xx.c. 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.

15) NULL pointer dereference

EUVDB-ID: #VU84096

Risk: Low

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

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.

Mitigation

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