Vulnerability from fkie_nvd - Published: 2024-05-19 11:15 - Updated: 2026-06-17 07:35
Severity
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
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.
