CVE-2022-3113: 
Linux Kernel vulnerability analysis and mitigation

Overview

CVE-2022-3113 is a vulnerability discovered in the Linux kernel through version 5.16-rc6. The issue specifically affects the mtkvcodecfwvpuinit function in drivers/media/platform/mtk-vcodec/mtkvcodecfwvpu.c, where it fails to check the return value of devmkzalloc(), potentially leading to a null pointer dereference (NVD, CVE Mitre).

Technical details

The vulnerability is classified as a NULL Pointer Dereference (CWE-476) with a CVSS v3.1 base score of 5.5 (Medium). The attack vector is local (AV:L), with low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), and affecting only the availability of the system (C:N/I:N/A:H) (NVD).

Impact

The vulnerability can lead to a null pointer dereference, which could potentially cause a system crash or denial of service condition. The impact is limited to availability with no direct effect on confidentiality or integrity of the system (NVD).

Mitigation and workarounds

The vulnerability was fixed in Linux kernel 5.18-rc1 through a patch that adds proper return value checking for devm_kzalloc(). The fix was implemented through commit e25a89f743b18c029bfbe5e1663ae0c7190912b0 (Kernel Commit).
