Description
A flaw was found in the Linux kernel's QCOM SNPS Femto V2 PHY driver. During an early runtime suspend, a timing window exists where the power management (PM) callbacks may attempt to access an uninitialized hardware-specific PHY (hsphy) instance. This can lead to a NULL pointer dereference, potentially causing a system crash or denial of service.
