Overview
About vulnerability
In the Linux kernel, the following vulnerability has been resolved: ALSA: hda: cs35l41: Fix NULL pointer dereference in cs35l41_hda_read_acpi() The acpi_get_first_physical_node() function can return NULL, in which case the get_device() function also returns NULL, but this value is then dereferenced without checking,so add a check to prevent a crash. Found by Linux Verification Center (linuxtesting.org) with SVACE. A flaw was found in the Linux kernel’s Advanced Linux Sound Architecture (ALSA) component. This vulnerability, a NULL pointer dereference, occurs in the cs35l41_hda_read_acpi() function when a null value is not properly handled. A local attacker could exploit this to trigger a system crash, resulting in a Denial of Service (DoS).Details
