In the Linux kernel, the following vulnerability has been resolved:

crypto: iaa - Fix async_disable descriptor leak

The disable_async paths of iaa_compress/decompress() don’t free idxd
descriptors in the async_disable case. Currently this only happens in
the testcases where req->dst is set to null. Add a test to free them
in those paths.
