GHSA-CRXP-PW8G-FQXP

Vulnerability from github – Published: 2024-11-07 12:30 – Updated: 2025-11-04 00:31

Details

In the Linux kernel, the following vulnerability has been resolved:

ALSA: hda/cs8409: Fix possible NULL dereference

If snd_hda_gen_add_kctl fails to allocate memory and returns NULL, then NULL pointer dereference will occur in the next line.

Since dolphin_fixups function is a hda_fixup function which is not supposed to return any errors, add simple check before dereference, ignore the fail.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Severity ?

5.5 (Medium)


                  
                    CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
