Vulnerability from fkie_nvd - Published: 2025-04-08 09:15 - Updated: 2025-10-28 17:09
Severity ?
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: dpll: 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 (pin). Fix it by checking if err is lower than zero. This wasn't found in real usecase, only noticed. Credit to Pierre.
