CVE-2026-68395

What the bug is

sata_dwc_enable_interrupts() is called before platform_get_irq() and ata_host_activate(), leaving the SATA controller's interrupt mask enabled without a registered handler. If a later step fails (irq request, phy init, etc.) or if the controller asserts an interrupt during probe, the irq line may fire with no handler, causing a spurious interrupt storm. Move sata_dwc_enable_interrupts() after ata_host_activate() so that interrupts are only unmasked once the handler is registered and the core is fully initialized.

Where it lives

The fix touches these files. If the subsystem is one you do not use, the practical exposure is lower, though the package is still the vulnerable one.

LIBATA SUBSYSTEM (Serial and Parallel ATA drivers)MAINTAINERS section matched on drivers/ata/ · linux-ide@vger.kernel.org · Maintained

Kernel module

none to look for. The file would have gone into sata_dwc_460ex, and Debian does not compile it into that module, so finding sata_dwc_460ex in lsmod would say nothing about this CVE.

Check it on the machine

grep -wE 'CONFIG_ATA|CONFIG_SATA_DWC' /boot/config-$(uname -r)

Reads the booted kernel's own configuration, on the machine and nowhere else. =y is built in, =m is a module, and an is not set line means the code is not there.

Show whether Debian builds this, per release

Debian does not build this code. In 5 releases below, every kernel flavour Debian publishes has the switch off, so the vulnerable file is compiled into no kernel binary Debian ships.

all on means the file is compiled; any one off means it is not.

From the configuration Debian publishes for every kernel flavour it builds. It covers only the architectures Debian ships a linux-config package for, and nothing about a kernel you built yourself.
