NULL Pointer Dereference in Linux Kernel ALSA ice1712 Driver

Publication date: 2026-07-25

Last updated on: 2026-07-25

Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: ALSA: ice1712: check snd_ctl_new1() return value snd_ctl_new1() can return NULL when memory allocation fails. The ice1712 driver calls snd_ctl_new1() without checking the return value before dereferencing the pointer in multiple places (ice1712.c, ice1724.c, aureon.c), which can lead to NULL pointer dereferences. Add NULL checks after snd_ctl_new1() calls and return -ENOMEM if any fails.

Executive Summary

This is a NULL pointer dereference vulnerability in the Linux kernel's ALSA sound driver (ice1712). The driver fails to check if snd_ctl_new1() returns NULL after memory allocation fails. This can lead to crashes or undefined behavior when the driver tries to use the NULL pointer.

Detection Guidance

This vulnerability is specific to the Linux kernel's ALSA sound subsystem (ice1712 driver). Detection requires checking kernel logs for NULL pointer dereference errors related to snd_ctl_new1() in the ice1712, ice1724, or aureon modules. Use commands like dmesg | grep -i 'ice1712\|ice1724\|aureon\|NULL pointer' or journalctl -k | grep -i 'snd_ctl_new1\|NULL pointer dereference' to search for related errors.

Impact Analysis

If exploited, this could cause system instability, crashes, or denial of service on affected Linux systems using the ice1712 sound driver. It may require kernel restart to recover.

Compliance Impact

This vulnerability does not directly affect compliance with standards like GDPR or HIPAA. It is a local denial-of-service issue in the Linux kernel's ALSA sound driver due to a NULL pointer dereference, which could crash the system but does not involve data exposure or privacy violations.

Mitigation Strategies

Update your Linux kernel to the latest stable version that includes the fix for this vulnerability. If your distribution has not yet released a patched kernel, consider applying the upstream patch manually or disabling the affected ALSA modules (ice1712, ice1724, aureon) if not in use.
