CVE-2026-63977
|
| Sažetak |
In the Linux kernel, the following vulnerability has been resolved:
dpll: zl3073x: use __dpll_device_change_ntf() and remove change_work
The change_work was introduced to send device change notifications
from DPLL device callbacks without deadlocking on dpll_lock, since
the callbacks are already invoked under that lock. Now that
__dpll_device_change_ntf() is exported for callers that already
hold dpll_lock, use it directly and remove the change_work
infrastructure entirely.
This eliminates a race condition where change_work could be
re-scheduled after cancel_work_sync() during device teardown,
potentially causing the handler to dereference a freed or NULL
dpll_dev pointer. |
