Fedora 44 : valkey (2026-3d18a65cc4)

medium Nessus Plugin ID 331316

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 44 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-3d18a65cc4 advisory.

 ## Valkey 9.0.5 - Released Tue 21 July 2026

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

 ### Security Fixes

 * **CVE-2026-56684**: Fix a use-after-free in TLS connection handling that could allow an authenticated client to achieve remote code execution using CLIENT KILL (#4234)
 * **CVE-2026-63639**: Reject corrupt stream RDB files containing a shared NACK across consumers, which could allow remote code execution. Reported by @z0v3r1n and @lifip. (#4073)

 ### Bug Fixes

 * Strictly validate CRLF terminators when parsing the RESP protocol; malformed requests now get a protocol error instead of being misparsed by @enjoy-binbin (#2872)

 * Fix a NULL pointer crash in TLS pending-data handling by @zuiderkwast (#3641)
 * Fix a server crash when multiple RDMA clients disconnect at the same time by @quanyeyang (#3448)
 * Fix a use-after-free when ACL LOAD deletes a user whose clients cannot be freed immediately by @ranshid (#3800)
 * Fix a use-after-free when a module unregisters the first registered cluster message receiver for a message type by @eifrah-aws (#3846)
 * Fix HRANDFIELD looping forever when a hash has fewer non-expired fields than the requested count by @cjx-zar (#4047)
 * Fix clients being left on the wrong database after module keyspace notifications for commands like MOVE and COPY by @enjoy-binbin (#4024)
 * Fix a Sentinel crash during coordinated failover when the connection to the old primary is disconnected by @lukepalmer (#4068)
 * Fix underestimation of client output buffer memory when replies reference shared objects, so buffer limits are enforced correctly by @dvkashapov (#3306)
 * Fix a crash on ARM/aarch64 caused by memory-ordering races in the IO thread job queue by @jjuleslasarte (#3878)
 * Fix a crash when active hash field expiration leaves a single entry in a large expiration time-bucket by @ranshid (#3950)
 * Fix a file descriptor leak when a blocking connection attempt, such as MIGRATE to an unreachable host, times out by @madolson (#3541)
 * Fix a potential crash from a dangling slot migration job reference when the migration client is reset by @murphyjacob4 (#3554)
 * Remove cached EVAL scripts when their scripting engine is unregistered, preventing dangling engine references by @eifrah-aws (#3503)
 * Fix a memory leak in GEOSEARCH BYPOLYGON when argument parsing fails, such as on an invalid COUNT by @bandalgomsu (#3568)
 * Fix a crash when a slot migration target node is removed from the cluster before the migration connects by @chenshi5012 (#3596)
 * Fix a crash when the module GetLRU/SetLRU/GetLFU/SetLFU APIs are called with a NULL key by @yaronsananes (#3610)
 * Fix an assertion failure in hash field expiration commands when a module blocks the client in a keyspace notification by @enjoy-binbin (#3743)
 * Fix a cluster UPDATE log message reading shard IDs past their fixed-length buffer by @enjoy-binbin (#3942)
 * Fix undefined behavior in the failover delay calculation when cluster-node-timeout is set below 30 milliseconds by @enjoy-binbin (#3941)
 * Reject zipmap RESTORE payloads with overflowing length fields that could cause out-of-bounds access on 32-bit builds by @madolson (#3920)
 * Reject NAN scores in listpack- and ziplist-encoded sorted sets on RDB/RESTORE load, preventing a later crash on skiplist conversion by @madolson (#3921)

 * Fix corrupted client replies when IO threads are enabled, caused by a race between in-flight writes and reply buffer reuse by @nanyan0312 (#4060)
 * COMMAND INFO in RESP3 now returns the subcommands field as an Array instead of a Set for commands without subcommands by @rickrams (#3939)
 * The dual-channel replication RDB connection now announces the configured replica-announce-ip, avoiding stale replica entries behind NAT by @jdheyburn (#2846)
 * Prevent replicas from processing stale cluster packets and incorrectly promoting themselves to an empty primary within a shard by @zhijun42 (#2811)
 * Send the replica version on the dual-channel RDB connection so full syncs of data like hash field TTLs no longer fail by @hpatro (#4105)
 * Fix slot migration failure handling running twice on ownership changes and an out-of-order error reply in the internal SYNCSLOTS FINISH command by @chx9 (#3723)
 * Allow slot-migration-max-failover-repl-bytes to be set to -1 to disable the limit, as documented by @enjoy-binbin (#3443)

 * Reject control characters and delimiters in cluster AUX fields and validate cluster-announce-ip to prevent nodes.conf corruption or injection by @eifrah-aws (#3848)
 * Fix changes to lua-enable-insecure-api via CONFIG SET not taking effect when the option was set at startup by @enjoy-binbin (#4182)
 * Fix incorrect memory overhead reported for watched keys in client memory usage tracking by @enjoy-binbin (#3359)
 * Replica logs now report 'Connection reset by peer' instead of the misleading 'Success' when the primary closes the connection by @abmathur-ie (#3580)
