Valkey 7.2.15 - Released Mon 26 October 2026

Upgrade urgency SECURITY: This release includes security fixes we recommend you apply as soon as possible.

Security Fixes

GHSA-f4q9-j22m-xqq9: Fix a heap buffer overflow in cluster Pub/Sub message construction that could allow an authenticated client to crash the server or potentially execute arbitrary code by publishing an oversized message by @roshkhatri (#5030)

Bug Fixes

Fix a double-free crash when a module timer callback stops its own timer with ValkeyModule_StopTimer by @quanyeyang (#4211)
Truncate a partially written MULTI block from the AOF on short read, preventing loss of newer writes after a later restart by @chzhoo (#4342)
Fix an ACL bypass where duplicate STORE/STOREDIST options let GEORADIUS write or delete keys outside the user's permitted patterns by @tjade273 (#3971)
Fix a use-after-free crash when a module's cluster message type is received after the module is unloaded by @enjoy-binbin (#4360)
Fix out-of-bounds access for cluster module message type 255, which is now a valid, dispatchable message type by @enjoy-binbin (#4410)
AOF loading no longer performs ACL checks on replayed commands, preventing silent data loss when the default user is disabled by @lukepalmer (#3984)
Listpacks are now always validated on RDB load and RESTORE, preventing deferred assertion crashes; sanitize-dump-payload and its ACL flags become no-ops by @jjuleslasarte (#3721)
Fix a client memory accounting leak on replicas that inflated the mem_clients_normal INFO field after primary disconnections by @enjoy-binbin (#4395)
Fix stream commands that mutate consumer-group or PEL state (XGROUP, XSETID, XREADGROUP, XACK, XCLAIM, XAUTOCLAIM) not triggering WATCH and client-side tracking invalidation by @Tarte12 (#3459)
Fix a server abort on a RESTORE payload declaring a string length that overflows the allocation size; such payloads are now rejected as bad data by @enjoy-binbin (#4733)
Fix ZINTER/ZINTERSTORE returning input-order-dependent scores when a weighted term is 0*inf; a NaN weighted score now counts as 0, matching ZUNION by @leomurillo (#4997)
Harden stream validation on RDB load and RESTORE so crafted payloads can no longer crash the server on later commands by @madolson (#3922)
Fix a use-after-free crash when serving clients blocked on the same key if one client is freed during processing by @quanyeyang (#4212)
Fix a stack overflow crash in TLS connections when retrying a large write after a write failure by @murphyjacob4 (#4307)
Fix a crash from forged cluster bus PUBLISH or MODULE packets declaring payload lengths that exceed the packet size by @tjade273 (#3972)
Correct ValkeyModule_FreeModuleUser, ValkeyModule_ACLAddLogEntry and ValkeyModule_ACLAddLogEntryByUserName declarations to return int as implemented, fixing undefined behavior on targets with strict call signature checks by @rainsupreme (#4676)
Fix valkey-benchmark spinning on would-block writes, which could starve reply processing and the --duration timer by @thweetkomputer (#4567)
Fix a huge memory allocation when a command such as COMMAND GETKEYS EVAL declares a far larger key count than the arguments provided by @murphyjacob4 (#3598)
Reject stream payloads with mismatched live/deleted record counts, preventing XDEL from destroying unaccounted entries by @roshkhatri (#4381)
Fix a server crash when loading an ACL file containing a selector with an unmatched parenthesis by @magic-peach (#4214)
Fix cluster config saving to avoid publishing truncated nodes.conf files, losing the startup lock after the first save, and failing every save on SMB filesystems such as Azure Files; the lock now lives on a separate nodes.conf.lock file by @KewangZhili (#4489)
Fix LSET on 64-bit builds silently modifying the wrong element for out-of-range indexes instead of returning an index out of range error by @charsyam (#4823)
