CVE-2026-90360
Estado: RecibidaSin puntuar—
In the Linux kernel, the following vulnerability has been resolved:
regulator: core: use system_freezable_wq for init complete work
schedule_delayed_work() uses system_wq, which is non-freezable, allowing regulator_init_complete_work to run concurrently with system suspend. This work fires ~30s after boot to disable unused regulators via I2C. When it races with PM suspend, the I2C adapter may already be suspended, triggering a -ESHUTDOWN warning in __i2c_transfer():
Switch to system_freezable_wq so the work is frozen before any device is suspended, eliminating the race.
