CVE-2026-64480 Details
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.
A vulnerability has been identified in the Linux kernel's ALSA ice1712 driver, where the function snd_ctl_new1() is called without proper validation of its return value. This oversight can lead to NULL pointer dereferences, as the function may return NULL if memory allocation fails. The issue is present in multiple files within the ice1712 driver, including ice1712.c, ice1724.c, and aureon.c. The vulnerability arises because the driver does not check for successful memory allocation before using the pointer, potentially causing crashes or undefined behavior.
The vulnerability has been addressed by adding NULL checks after the snd_ctl_new1() calls in the affected files. Users can apply the available patch to their Linux kernel to mitigate this issue.
