How to fix?

Upgrade SLES:15.2 kernel-docs to version 5.3.18-150200.24.194.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-docs package and not the kernel-docs package as distributed by SLES. See How to fix? for SLES:15.2 relevant fixed versions and status.

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

ALSA: pcm: oss: Fix negative period/buffer sizes

The period size calculation in OSS layer may receive a negative value as an error, but the code there assumes only the positive values and handle them with size_t. Due to that, a too big value may be passed to the lower layers.

This patch changes the code to handle with ssize_t and adds the proper error checks appropriately.
