Update urgency: SECURITY: There are security fixes in the release.

• (CVE-2026-62356) Miscalculated buffer size in CMSketch RDB loading may lead to heap OOB write
• Out-of-bounds access in TopK heap cleanup path (MOD-15410)
• Use-after-free in the TLS pending-data list when a command closes another pending connection
• A malicious RDB payload with an out-of-range SLOT_INFO slot id causes memory corruption during RDB loading, which may lead to Remote Code Execution
• Vector Sets: missing node level validation when loading a vector set from RDB may lead to out-of-bounds access
• Vector Sets: use-after-free when VREM mutates the HNSW graph while background VSIM threads are still running
• Vector Sets: a negative hnsw_search() return was treated as a huge unsigned count, reading past the end of the result arrays
• TLS client certificate authentication bypass: a Common Name containing an embedded NUL byte was truncated, allowing a client to authenticate as another (possibly privileged) ACL user
• #15594 Use-after-free in the blocked-client list when reprocessing a command evicts another client blocked on the same key
