NewCVE-2026-90280 (opens in a new tab)How to fix?
Upgrade Debian:12 linux-6.12 to version 6.12.111-1~deb12u1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream linux-6.12 package and not the linux-6.12 package as distributed by Debian.
See How to fix? for Debian:12 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
phy: qcom: qmp-usb: 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.
