AI-suggested
A fix has been implemented in the Linux kernel to correct the error path in devm_qce_register_algs. Users should apply the official kernel updates that include this patch. Since this is not a cloud service, remediation requires updating the affected Linux kernel versions once patches are available. Patch status is not explicitly confirmed in the provided data; check the vendor advisory for current remediation guidance.
Description
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.
