Detailsinfo

A vulnerability classified as very critical has been found in Linux Kernel up to 7.2.4/7.3-rc1. This affects the function regulator_is_enabled of the component hd3ss3220. The manipulation with an unknown input leads to a state issue vulnerability. CWE is classifying the issue as CWE-371. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: usb: typec: hd3ss3220: track VBUS enable state per consumer regulator_is_enabled() reports the aggregate regulator state, not whether this consumer holds an enable reference. If another consumer enables VBUS first, the driver can skip its own regulator_enable() call and later attempt to drop a reference it never acquired, triggering an unbalanced regulator disable warning. Track successful enable and disable calls locally. Keep the state unchanged when an operation fails so a later role or ID notification retries the operation while this consumer keeps balanced references.

The advisory is shared at git.kernel.org. This vulnerability is uniquely identified as CVE-2026-90028 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 $5k-$25k at the moment (estimation calculated on 09/16/2026).

Upgrading to version 7.2.5 or 7.3-rc2 eliminates this vulnerability. Applying the patch df7cd3908e07503fa7e9737dacf44208530e58d9/c9a48db776d7184981630ecc01a3ad30a8f7dc24 is able to eliminate this problem. The best possible mitigation is suggested to be upgrading to the latest version.
