CVE-2026-90360 PUBLISHED

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():

WARNING: ... at __i2c_transfer+0x36c/0x3c8 Call trace: __i2c_transfer i2c_transfer regmap_i2c_write _regmap_update_bits regulator_disable_regmap _regulator_do_disable regulator_late_cleanup regulator_init_complete_work_function process_one_work

Switch to system_freezable_wq so the work is frozen before any device is suspended, eliminating the race.
