A resource leak vulnerability exists in the Linux kernel's mfd: arizona driver due to improper error handling in the wm5102_clear_write_sequencer() function. When this helper function fails, it returns early without executing the necessary cleanup sequence, causing regulators to remain enabled and leading to a resource leak. This issue has been fixed by changing the error handling to properly free resources on failure.
AI Analysis
Technical Summary
The vulnerability in the Linux kernel mfd: arizona driver involves the wm5102_clear_write_sequencer() function, which may return an error and bypass the cleanup sequence. This results in regulators remaining enabled, causing a resource leak (CWE-401). The fix involves modifying the error path to jump to an error reset label that properly frees resources, preventing the leak.
Potential Impact
The vulnerability causes a resource leak that can lead to reduced system stability or availability due to regulators remaining enabled unnecessarily. There is no impact on confidentiality or integrity. The CVSS vector indicates local attack complexity with low privileges required and no user interaction, resulting in a medium severity rating.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. The description indicates that a fix has been implemented in the Linux kernel source code by correcting the error handling path. Users should apply the relevant Linux kernel updates once available to resolve this issue.
