Description OSIDB Bzimport 2024-07-29 18:21:44 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ALSA: emux: improve patch ioctl data validation

In load_data(), make the validation of and skipping over the main info
block match that in load_guspatch().

In load_guspatch(), add checking that the specified patch length matches
the actually supplied data, like load_data() already did.
