In the Linux kernel, the following vulnerability has been resolved:
phy: qcom: snps-femto-v2: Fix possible NULL-deref on early runtime suspend
Runtime PM must be enabled before creating the PHY, since phy_create()
only enables runtime PM on the PHY device if it is already enabled on
this parent device. However, the runtime PM callbacks dereference the
hsphy instance, which is not yet ready, leaving a window where a suspend
callback may trigger a NULL pointer dereference.
Take a runtime PM usage reference with pm_runtime_get_noresume() before
enabling runtime PM and release it once the PHY has been created, so that
no runtime suspend can run before the PHY is ready. This also prevents a
short window where an unnecessary runtime suspend can occur.
Use the devres-managed version to ensure PM runtime is symmetrically
disabled during driver removal for proper cleanup.
