Description OSIDB Bzimport 2025-12-16 15:04:19 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ASoC: SDCA: bug fix while parsing mipi-sdca-control-cn-list

"struct sdca_control" declares "values" field as integer array.
But the memory allocated to it is of char array. This causes
crash for sdca_parse_function API. This patch addresses the
issue by allocating correct data size.
