CVE-2026-97507

What the bug is

The return value of dm1105_dma_map(), which handles DMA memory allocation, is ignored in dm1105_hw_init(). If dma_alloc_coherent() fails, the driver will proceed using a NULL pointer for DMA transfers, leading to a kernel oops or invalid hardware access. Fix this by checking the return value and propagating -ENOMEM on failure.

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.

Kernel module

dm1105

Check it on the machine

grep -w CONFIG_DVB_DM1105 /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.

lsmod | grep -w dm1105

Prints a line if that module is loaded right now, and nothing if it is not. One that is not loaded can still be loaded later by anything that needs it.

Show whether Debian builds this, per release

Debian builds this, but not on every flavour. At least one release below builds the code on some of its kernel flavours and not on others, so the answer depends on the architecture and flavour installed.

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.
