Detailsinfo

A vulnerability, which was classified as problematic, was found in Linux Kernel up to 7.2.5. This affects the function regulator_init_complete_work_function of the component regulator. The manipulation with an unknown input leads to a race condition vulnerability. CWE is classifying the issue as CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. This is going to have an impact on integrity, and availability. The summary by CVE is:

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.

The advisory is shared at git.kernel.org. This vulnerability is uniquely identified as CVE-2026-90360 since 09/11/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 09/17/2026).

Upgrading to version 4.9.207, 4.14.160, 5.10.270, 5.15.221, 6.1.188, 6.6.157, 6.12.110, 6.18.52, 7.2.6 or 7.3-rc1 eliminates this vulnerability. Applying the patch 8a2ae3ab348cce44120667277c2198f10cc348b1/350a0cba90e1bd40b1fe5b396923d2f3a61d1056/2cebc00340a585adeffe321bc41f1937eb79a4dc/9cf65270c1c1717c84dcfacd58a782c1186b0cbf/dc8570a5b830190bf0b57017c35aef97cd6ad7d9/6d0a2c5e210f2fba099129e6183ef81316a6ae48/0d23d658d79925076026fff62a49b8c94e0e8922/0b950aa7ec95e120b2bde745ca9a7ed3ce49d528/29dc2e24f6adb36dcb884acf455644c397a67471/03eab318cedd6ae34ecd34533cd986edf5237164 is able to eliminate this problem. The best possible mitigation is suggested to be upgrading to the latest version.
