Description SMASH SMASH 2024-05-20 16:04:08 UTC

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.

Hi Oliver,

Because this is a issue for crypto. Could you please help to handle it?

If this is not in your area, just reset bug assigner to kernel-bugs@suse.de. Kernel Security Sentinel will find other expert.

Thanks a lot!

No other kernel is affected
