Description
Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: libertas_tf: fix UAF in lbtf_free_adapter()
lbtf_free_adapter() calls lbtf_free_cmd_buffer() to free the command
buffers before calling timer_delete_sync() to wait for the command
timer callback. If the timer callback (command_timer_fn) is already
running when lbtf_free_cmd_buffer() frees the command array, the
callback dereferences priv->cur_cmd->cmdbuf which points to freed
memory.
Swap the order so that timer_delete_sync() runs first, ensuring any
in-flight callback has completed before the command buffers are freed.
