Name of the Vulnerable Software and Affected Versions Cortex-A77 cores versions r0p0 and r1p0

Description The issue arises when software, under certain circumstances, could deadlock a core due to the execution of either a load to device or non-cacheable memory, and either a store exclusive or register read of the Physical Address Register (PAR EL1) in close proximity.

Recommendations For Cortex-A77 cores versions r0p0 and r1p0, consider implementing software workarounds to avoid the execution of load to device or non-cacheable memory and store exclusive or register read of the Physical Address Register (PAR EL1) in close proximity to prevent core deadlock. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
