DEBIAN-CVE-2025-40182

In the Linux kernel, the following vulnerability has been resolved: crypto: skcipher - Fix reqsize handling Commit afddce13ce81d ("crypto: api - Add reqsize to cryptoalg") introduced crareqsize field in cryptoalg struct to replace type specific reqsize fields. It looks like this was introduced specifically for ahash and acomp from the commit description as subsequent commits add necessary changes in these alg frameworks. However, this is being recommended for use in all crypto algs [1] instead of setting reqsize using crypto*setreqsize(). Using crareqsize in skcipher algorithms, hence, causes memory corruptions and crashes as the underlying functions in the algorithm framework have not been updated to set the reqsize properly from crareqsize. [2] Add proper set_reqsize calls in the skcipher init function to properly initialize reqsize for these algorithms in the framework.
