CVE-2023-54233 Details
Description
In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: avoid a NULL dereference with unsupported widgets If an IPC4 topology contains an unsupported widget, its .module_info field won't be set, then sof_ipc4_route_setup() will cause a kernel Oops trying to dereference it. Add a check for such cases.
A vulnerability in the Linux kernel's ASoC SOF component can lead to a NULL pointer dereference. This issue occurs when an IPC4 topology includes an unsupported widget, causing its .module_info field to remain unset. As a result, the function sof_ipc4_route_setup() attempts to dereference a NULL pointer, leading to a kernel Oops error. The vulnerability affects several versions of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. Instructions for downloading the patched version are available on the Linux kernel official website.
