Mô tả CVE
In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Unwind debug trap enable on copy_to_user failure
If kfd_dbg_trap_enable() fails while copying runtime_info to userspace,
it had already activated the trap, set debug_trap_enabled, taken an extra
process reference, and opened the debug event file. Return -EFAULT without
unwinding that state, leaving inconsistent trap state and a refcount
imbalance that could break later DISABLE/ENABLE.
On copy_to_user failure, deactivate the trap and undo the rest of the
enable setup before returning.
