{"id":"AZL-102236","summary":"CVE-2026-90360 affecting package kernel 6.6.150.1-1","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   __i2c_transfer\n   i2c_transfer\n   regmap_i2c_write\n   _regmap_update_bits\n   regulator_disable_regmap\n   _regulator_do_disable\n   regulator_late_cleanup\n   regulator_init_complete_work_function\n   process_one_work\n\nSwitch to system_freezable_wq so the work is frozen before any device\nis suspended, eliminating the race.","modified":"2026-09-18T14:17:49.998015807Z","published":"2026-09-17T17:17:34Z","upstream":["CVE-2026-90360"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90360"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-102236.json"}}],"schema_version":"1.9.0"}
