In the Linux kernel, the following vulnerability has been resolved: firmware: csdsp: Fix OOB memory read access in KUnit test (ctl cache) KASAN reported out of bounds access - csdspctlcacheinitmultipleoffsets(). The code uses mockcoefftemplate.lengthbytes (4 bytes) for register value allocations. But later, this length is set to 8 bytes which causes test code failures. As fix, just remove the lenght override, keeping the original value 4 for all operations.
