CVE-2023-52769:
Linux Kernel vulnerability analysis and mitigation
Overview
CVE-2023-52769 is a vulnerability in the Linux kernel's wifi subsystem, specifically in the ath12k driver for Qualcomm Wi-Fi 7 devices. The vulnerability was discovered in the htt mlo-offset event handling code where there was a potential race condition due to improper RCU (Read-Copy-Update) protection (Kernel Commit).
Technical details
The vulnerability stems from the ath12k active pdevs being protected by RCU, but the htt mlo-offset event handling code calling ath12k_mac_get_ar_by_pdev_id() was not properly marked as a read-side critical section. This could potentially lead to use-after-free issues in the kernel's wifi subsystem (Kernel Commit).
Impact
The vulnerability could potentially lead to use-after-free issues in the kernel's wifi subsystem, which might affect system stability and security (Kernel Commit).
Mitigation and workarounds
The issue has been fixed by marking the code in question as an RCU read-side critical section. The fix was implemented in the Linux kernel through commit afd3425bd69610f318403084fe491e24a1357fb9 (Kernel Commit).
