{"id":"CVE-2026-90360","summary":"regulator: core: use system_freezable_wq for init complete work","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nregulator: core: use system_freezable_wq for init complete work\n\nschedule_delayed_work() uses system_wq, which is non-freezable, allowing\nregulator_init_complete_work to run concurrently with system suspend. This\nwork fires ~30s after boot to disable unused regulators via I2C. When it\nraces with PM suspend, the I2C adapter may already be suspended, triggering\na -ESHUTDOWN warning in __i2c_transfer():\n\n  WARNING: ... at __i2c_transfer+0x36c/0x3c8\n  Call trace:\n
