Flaw in Wireless Driver of Ath12k Product Line

CVE-2024-56607

What is CVE-2024-56607?

A vulnerability has been identified within the ath12k wireless driver in the Linux kernel, specifically related to the handling of bitrate settings. This issue emerges when manual bitrate configurations are attempted, resulting in an error due to function calls being made in an invalid context. Consequently, users attempting to set specific bitrate masks may encounter system instability, complicating wireless operations. While a fix has been implemented to address atomic call issues in the ath12k_mac_op_set_bitrate_mask() function, concerns remain regarding the compatibility of some firmware, particularly the WCN6855, with the bitrate WMI commands. This raises questions about the necessity of disabling the conflicting function to enhance system performance. For users and administrators, it is crucial to remain vigilant and apply updates to mitigate potential disruptions.
