  s390/zcrypt: Pad trailing CCA or EP11 message with zeros (2026-08-05 15:12:22 +0200)

----------------------------------------------------------------
s390 updates for 7.2-rc7

- Fix potential uninitialized memory reads and buffer overflows from
  malformed zcrypt CCA and EP11 requests by properly validating lengths
  and payloads

- Fix possible out of bounds accesses in zcrypt EP11 domain handling by
  replacing fixed payload layout assumptions with parsing ASN.1 fields
  with bounds checks

- Fix zcrypt CCA and EP11 request and reply buffer allocations missing
  required 4-byte padding, and scrub the full allocation on release

- Fix zcrypt CCA and EP11 messages leaking up to 3 uninitialized bytes
  of memory by zeroing trailing alignment padding
