CVE-2025-38082

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

gpio: virtuser: fix potential out-of-bound write

If the caller wrote more characters, count is truncated to the max available space in "simple_write_to_buffer". Check that the input size does not exceed the buffer size. Write a zero termination afterwards.

This vulnerability does not impact Red Hat Enterprise Linux or other Red Hat offerings because the affected GPIO virtual user driver is not present in supported kernels. The issue stems from insufficient bounds checking in driver interfaces introduced in newer upstream releases. As the vulnerable subsystem is not compiled into Red Hat enterprise kernels, there is no operational risk to Red Hat environments.
