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
----------------------------------------------------------------
