CVE-2026-45875 Details
Description
In the Linux kernel, the following vulnerability has been resolved: mfd: arizona: Fix regulator resource leak on wm5102_clear_write_sequencer() failure The wm5102_clear_write_sequencer() helper may return an error and just return, bypassing the cleanup sequence and causing regulators to remain enabled, leading to a resource leak. Change the direct return to jump to the err_reset label to properly free the resources.
A resource leak vulnerability has been identified in the Linux kernel's Arizona multi-function device (MFD) driver, specifically within the WM5102 codec handling. The issue arises in the 'wm5102_clear_write_sequencer()' function, which may return an error without properly cleaning up, leaving regulators enabled and causing a resource leak. This vulnerability affects several versions of the Linux kernel.
The vulnerability has been addressed in the Linux kernel. Users can upgrade to the latest version to apply the fix.
