In the Linux kernel, the following vulnerability has been resolved: ALSA: ice1712: check snd_ctl_new1() return value snd_ctl_new1() can return NULL… (CVE-2026-64480)
A vulnerability in the Linux kernel ALSA ice1712 driver was resolved by adding checks for NULL return values from snd_ctl_new1(), which can return NULL on memory allocation failure. Without these checks, the driver could dereference NULL pointers, causing kernel crashes. The fix adds NULL checks and returns -ENOMEM on failure.
AI Analysis
Technical Summary
The ALSA ice1712 driver in the Linux kernel called snd_ctl_new1() without verifying if it returned NULL, which can happen when memory allocation fails. This lack of validation led to potential NULL pointer dereferences in multiple driver files (ice1712.c, ice1724.c, aureon.c). The vulnerability was addressed by adding NULL checks after snd_ctl_new1() calls and returning an error code (-ENOMEM) if the allocation failed, preventing kernel crashes due to NULL dereferences.
Potential Impact
This vulnerability can cause NULL pointer dereferences in the Linux kernel ALSA ice1712 driver, potentially leading to kernel crashes or denial of service. There is no indication of code execution or privilege escalation from the provided data.
Mitigation Recommendations
A fix has been applied to the Linux kernel source to add NULL checks after snd_ctl_new1() calls in the ice1712 driver and return -ENOMEM on failure. Users should update to a Linux kernel version that includes this fix. Patch status is not explicitly confirmed in the provided data; check the official Linux kernel advisories or vendor updates for the fixed versions.
