Description

In the Linux kernel, the following vulnerability has been resolved: ipmi:ssif: Fix a memory leak when scanning for an adapter The adapter scan ssif_info_find() sets info->adapter_name if the adapter info came from SMBIOS, as it's not set in that case. However, this function can be called more than once, and it will leak the adapter name if it had already been set. So check for NULL before setting it.

Affected products

Linux kernel: 5.4 — fixed in 6.6

How to fix

Upgrade to a fixed version: Linux kernel 6.6. Check the vendor advisory for mitigations.
