In the Linux kernel, the following vulnerability has been resolved:

arm64: dts: qcom: qcs615: fix a crash issue caused by infinite loop for Coresight

An infinite loop has been created by the Coresight devices. When only a
source device is enabled, the coresight_find_activated_sysfs_sink function
is recursively invoked in an attempt to locate an active sink device,
ultimately leading to a stack overflow and system crash. Therefore, disable
the replicator1 to break the infinite loop and prevent a potential stack
overflow.
