- Summary
- CVE-2026-98527 affecting package kernel 6.6.157.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
gpio: zynq: fix runtime PM leak on request error path
pm_runtime_get_sync() leaves the usage counter incremented even when it fails, and zynq_gpio_request() returns the error without dropping it.
gpiolib does not call ->free() when ->request() fails, so zynq_gpio_free(), which holds the only matching pm_runtime_put(), never runs. The reference is leaked and the controller can no longer runtime-suspend, so its clock stays enabled.
Switch to pm_runtime_resume_and_get(), which only increments the usage counter on success.
