The vulnerability of the tmc_enable_etr_sink_sysfs() function in the drivers/hwtracing/coresight/coresight-tmc-etr.c file of the Linux operating system’s hardware tracing driver allows a hacker to cause a service failure.

The vulnerability of the tmcenableetrsinksysfs function in the drivers/hwtracing/coresight/coresight-tmc-etr.c file of the Linux kernel’s hardware tracing driver is related to synchronization errors when using shared resources. Exploiting this vulnerability can allow an attacker to cause a servic...
