GHSA-MFPV-C7R6-4Q9W

Vulnerability from github – Published: 2025-04-08 09:31 – Updated: 2025-10-28 18:30

Details

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.

This wasn't found in real usecase, only noticed. Credit to Pierre.

Severity ?

5.5 (Medium)
