CVE-2025-22017

Description

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

devlink: fix xa_alloc_cyclic() error handling

In case of returning 1 from xa_alloc_cyclic() (wrapping) ERR_PTR(1) will be returned, which will cause IS_ERR() to be false. Which can lead to dereference not allocated pointer (rel).

Fix it by checking if err is lower than zero.
