About this tag
The coresight etr tag on WindowsForum.com covers discussions about the Linux kernel's Coresight Embedded Trace Relay (ETR) driver, particularly a use-after-free vulnerability (CVE-2025-68376) that occurs when the ETR buffer is resized while active in sysfs mode. This bug can cause memory corruption and system instability. The fix involves a surgical change to the coresight TMC-ETR code to prevent the driver from using freed memory. While the tag is Linux-specific, it may interest Windows users involved in cross-platform development, embedded systems, or security research who encounter Coresight trace hardware on ARM-based systems.
