CVE-2026-31777 Details
Description
In the Linux kernel, the following vulnerability has been resolved: ALSA: ctxfi: Check the error for index mapping The ctxfi driver blindly assumed a proper value returned from daio_device_index(), but it's not always true. Add a proper error check to deal with the error from the function.
A vulnerability in the Linux kernel's ALSA ctxfi driver arises from inadequate error handling in the 'daio_device_index()' function. The driver improperly assumed that the function would always return a valid index, which is not the case. This issue has been addressed by implementing a proper error check to validate the function's output. The vulnerability affects the Linux kernel stable tree.
Users can upgrade to the latest version of the Linux kernel stable tree to address this vulnerability.
