  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\niio: light: gp2ap002: Fix unbalanced runtime PM on repeated event writes\n\nThe IIO core does not filter duplicate writes to the event enable\nattribute, so writing the same value twice invokes\nwrite_event_config() twice. Enabling twice leaks a runtime PM\nreference, preventing the device from ever suspending again;\ndisabling twice underflows the usage count and triggers a\n\"Runtime PM usage count underflow\" warning.\n\nBail out early when the requested state matches the current state.\nWhile at it, switch to pm_runtime_resume_and_get() so a failed\nresume is propagated to userspace instead of silently marking the\nevent enabled.",
