CVE-2022-50294 Details
Description
In the Linux kernel, the following vulnerability has been resolved: wifi: libertas: fix memory leak in lbs_init_adapter() When kfifo_alloc() failed in lbs_init_adapter(), cmd buffer is not released. Add free memory to processing error path.
A memory leak vulnerability has been identified in the Linux kernel's WiFi Libertas driver. This issue arises in the 'lbs_init_adapter' function, where the 'kfifo_alloc' function's failure to allocate memory for the command buffer is not properly handled. As a result, the allocated command buffer is not released, leading to a memory leak. The vulnerability affects several versions of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel, where this vulnerability has been addressed. Instructions for upgrading the Linux kernel can be found in the official Linux documentation or through the package management system of the respective Linux distribution.
