CVE-2025-39931
In the Linux kernel, the following vulnerability has been resolved:
crypto: af_alg - Set merge to zero early in af_alg_sendmsg
If an error causes af_alg_sendmsg to abort, ctx->merge may contain
a garbage value from the previous loop. This may then trigger a
crash on the next entry into af_alg_sendmsg when it attempts to do
a merge that can't be done.
Fix this by setting ctx->merge to zero near the start of the loop.
