Description OSIDB Bzimport 2026-09-04 17:33:23 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ASoC: SDCA: Make UMP message size check more robust

If message offset was larger than the buffer length the size
check will pass incorrectly. Refactor the check such that it is
more robust to invalid sizes.
