CVE-2026-53065

What the bug is

The regmap_field objects allocated at player init are never freed and may leak resources if the driver is removed. Switch to devm_regmap_field_alloc() to automatically limit the lifetime of the allocations the lifetime of the device.

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.

sound/soc/sti/uniperif_player.c

Kernel module

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

Check it on the machine

grep -wE 'CONFIG_SND|CONFIG_SND_SOC|CONFIG_SND_SOC_STI' /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 4 releases below, every kernel flavour Debian publishes has the switch off, so the vulnerable file is compiled into no kernel binary Debian ships.

• bookworm, trixie, forky, sidn

n

not enabled on any flavour - this release does not build the code

Build switches

CONFIG_SND, CONFIG_SND_SOC, CONFIG_SND_SOC_STI

Reads as

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. Debian's own status above stays authoritative about the source package.MAINTAINERS kbuild Makefiles Debian linux-config packages
