CVE-2025-68370

Estado: AplazadaAlta (7.8)—

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

coresight: tmc: add the handle of the event to the path

The handle is essential for retrieving the AUX_EVENT of each CPU and is required in perf mode. It has been added to the coresight_path so that dependent devices can access it from the path when needed.

The existing bug can be reproduced with: perf record -e cs_etm//k -C 0-9 dd if=/dev/zero of=/dev/null

Showing an oops as follows: Unable to handle kernel paging request at virtual address 000f6e84934ed19e
