CVE-2023-53710:
Linux Kernel vulnerability analysis and mitigation
Overview
A vulnerability in the Linux kernel's WiFi subsystem (CVE-2023-53710) was identified affecting the mt7921 driver. The issue involves a NULL pointer dereference that occurs when the ACPI SAR (Specific Absorption Rate) table is not properly implemented (NVD).
Technical details
The vulnerability manifests as a kernel NULL pointer dereference at address 0x0000000000000004 when accessing an improperly implemented ACPI SAR table. The issue occurs in the mt7921initacpisar function within the mt7921common module, leading to a supervisor read access fault in kernel mode (NVD, RedHat).
Impact
When triggered, the vulnerability results in a kernel oops condition with a PREEMPT SMP NOPTI error, potentially affecting system stability and causing denial of service conditions (NVD).
Mitigation and workarounds
The issue has been resolved in the Linux kernel through a fix that properly handles the error code return to mark invalid ACPI SAR tables. Various Linux distributions have released patches, including Debian which has fixed versions available across multiple releases (Debian).
