Azure Linux 3.0 Security Update: hyperv-daemons (CVE-2023-52663)

medium Nessus Plugin ID 295589

Synopsis

The remote Azure Linux host is missing one or more security updates.

Description

The version of hyperv-daemons 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-2023-52663 advisory.

 - In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: amd: Fix memory leak in amd_sof_acp_probe() Driver uses kasprintf() to initialize fw_{code,data}_bin members of struct acp_dev_data, but kfree() is never called to deallocate the memory, which results in a memory leak. Fix the issue by switching to devm_kasprintf(). Additionally, ensure the allocation was successful by checking the pointer validity. (CVE-2023-52663)

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

Solution

Update the affected packages.
