Description

This security bulletin contains information about 2 vulnerabilities.


1) NULL pointer dereference (CVE-ID: CVE-2023-6176)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: 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


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.


2) Use-after-free (CVE-ID: CVE-2023-6932)

CWE-ID: CWE-416 - Use After Free

The vulnerability allows a local authenticated user to execute arbitrary code.

The vulnerability exists due to a use-after-free error within the ipv4 igmp component in Linux kernel. A local authenticated user can trigger a use-after-free error and execute arbitrary code.
