In the Linux kernel, the following vulnerability has been resolved: crypto: hisilicon/qm - increase the memory of local variables Increase the buffer to prevent stack overflow by fuzz test. The maximum length of the qos configuration buffer is 256 bytes. Currently, the value of the 'val buffer' is only 32 bytes. The sscanf does not check the dest memory length. So the 'val buffer' may stack overflow.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-013808 advisory.

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

    Increase the buffer to prevent stack overflow by fuzz test. The maximum     length of the qos configuration buffer is 256 bytes. Currently, the value     of the 'val buffer' is only 32 bytes. The sscanf does not check the dest     memory length. So the 'val buffer' may stack overflow.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

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

Currently, the     value of the 'val buffer' is only 32 bytes. The sscanf does not check the dest memory length. So the 'val     buffer' may stack overflow. (CVE-2022-50407)

Note that Nessus relies on the presence of the package as reported by the vendor.
