CVE-2026-90282

Status: ReceivedUnscored—

In the Linux kernel, the following vulnerability has been resolved:

phy: qcom: qmp-usb-legacy: Fix possible NULL-deref on early runtime suspend

There is a small window where the runtime suspend callback may run after pm_runtime_enable() and before pm_runtime_forbid(). In this case, a crash occurs because runtime suspend/resume dereferences qmp->phy pointer, which is not yet initialized: `if (!qmp->phy->init_count) {`

This can also happen if user re-enables runtime-pm via the sysfs attribute before qmp phy is initialized.

Similarly to other qcom phy drivers, introduce a qmp->phy_initialized variable that can be used to avoid relying on the possibly uninitialized phy pointer.

CVSS

NVD hasn't assigned a CVSS score to this CVE (common since the April 2026 policy change).

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
