CVE-2026-31777

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 daiodeviceindex, but it's not always true. Add a proper error check to deal with the error from the function...

CVE-2026-31777

The CVE-2026-31777 entry concerns the Linux kernel ALSA ctxfi driver. The root cause is the driver’s missing validation of the return value from daio_device_index(), leading to incorrect assumptions and potential system instability. Documents indicate this has been resolved via patches. Remediati...

CVE-2026-31775

The CVE-2026-31775 issue affects the Linux kernel ALSA ctxfi driver. A refactor caused atc_get_resources() to loop over all DAIOTYP entries, causing SPDIF1 (a special type used only on hw20k1 CTSB073X) to be considered for hw20k2 where it has no definition. This could crash the kernel during DAIO...
