CVE-2023-53452

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.2.7

Description A race condition can occur in the wifi subsystem related to the rtw89 driver, specifically between the initialization and enabling of Network Address Translation (NAPI). This condition arises if the network device is registered before NAPI is initialized, and user space attempts to start the device, which then enables NAPI. This can lead to a kernel bug, indicated by an invalid opcode error. The issue is addressed by reordering functions and moving network device registration to be the final step in the PCI probe process, along with correcting error handling in rtw89 core register hw().

Recommendations Update the Linux kernel to version 6.2.7 or later.
