+Subject: [PATCH] Invalid Memory Access in Redis RESTORE Command
+ (CVE-2026-25243)
+
+CVE: CVE-2026-25243
+Upstream-Status: Backport [https://github.com/redis/redis/commit/b9dde6fc25dec6191b18374335a076a7b31e3d02]
+
+Backport Changes:
+- In src/rdb.c, the duplicate consumer PEL error path removes
+  streamFreeNACK(nack), using the 8.0.6 function signature; upstream removes
+  streamFreeNACK(s, nack).
+
+(cherry picked from commit b9dde6fc25dec6191b18374335a076a7b31e3d02)
