Descriptions

In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: fix memory leak in error handling path of idxd_alloc Memory allocated for idxd is not freed if an error occurs during
idxd_alloc(). To fix it, free the allocated memory in the reverse order
of allocation before exiting the function in case of an error.
