"The version of kernel installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore,
affected by a vulnerability as referenced in the CVE-2024-41002 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: crypto: hisilicon/sec - Fix memory
    leak for sec resource release The AIV is one of the SEC resources. When releasing resources, it need to
    release the AIV resources at the same time. Otherwise, memory leakage occurs. The aiv resource release is
    added to the sec resource release function. (CVE-2024-41002)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
