The vulnerabilities of the functions etm_event_start() (drivers/hwtracing/coresight/coresight-etm-perf.c) and tmc_etr_get_buffer() (drivers/hwtracing/coresight/coresight-tmc-etr.c) in the Linux operating system’s hardware tracing driver software allow attackers to compromise the confidentiality, integrity, and accessibility of protected information.

The vulnerabilities of the functions etmeventstart drivers/hwtracing/coresight/coresight-etm-perf.c and tmcetrgetbuffer drivers/hwtracing/coresight/coresight-tmc-etr.c in the Linux kernel’s hardware tracing driver are related to improper compliance with the specifications of the calling side...
