Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: qce - fix error path in devm_qce_register_algs
If ops->register_algs() fails, the error path repeatedly calls the same
ops->unregister_algs() from the failed registration. Use the loop index
to unregister the previously registered algorithms instead.
