Description
In the Linux kernel, the following vulnerability has been resolved:
misc: ocxl: fix possible double free in ocxl_file_register_afu
info_release() will be called in device_unregister() when info->dev's
reference count is 0. So there is no need to call ocxl_afu_put() and
kfree() again.
Fix this by adding free_minor() and return to err_unregister error path.
Affected configurations
• linux linux kernel (>= 5.2 < 5.4.198)
• linux linux kernel (>= 5.5 < 5.10.121)
• linux linux kernel (>= 5.11 < 5.15.46)
• linux linux kernel (>= 5.16 < 5.17.14)
• linux linux kernel (>= 5.18 < 5.18.3)
