CVE-2026-104192
Description détaillée
Dragonfly is an in-memory data store built for modern application workloads. Prior to 1.40, OpaqueObjLoader::CreateStream in src/server/rdb_load.cc can associate one streamNACK with a consumer group's global PEL and a consumer-local PEL, then free the shared object when a duplicate consumer entry is rejected. Cleanup subsequently frees the same object again. In the default configuration, where Dragonfly ships with authentication disabled, an unauthenticated client can trigger the double-free by sending a crafted serialized stream to RESTORE, causing allocator corruption, denial of service, and potentially attacker-controlled code execution as the Dragonfly service account. The source fix has not yet been mapped to a published release.

CVE-2026-96299
Missing limits on resource use in the match expression evaluator of MongoDB Server can cause the server to consume excessive memory. Internal schema validation operators that are meant only for server use are accepted in user-supplied query filters. When these operators are nested and applied to documents that contain arrays, the server evaluates every combination of array elements without a sufficient limit on the resources used. This can cause memory use to grow until the mongod process runs out of memory and terminates. The behavior can occur when an authenticated user with read-only privileges runs an aggregation query that nests these operators.
CVE-2026-96297
Use of freed memory in the aggregation feature of MongoDB Server can cause the server to read data from a memory area after it has been released. When an internal aggregation stage is combined with a batch size of 0, the server may read from memory that is no longer in use. Because that memory can be reused for other data before it is read, query results returned to the client may contain unrelated data from the server process. Depending on the state of memory at the time, the server process may also terminate unexpectedly. The behavior can occur when an authenticated user with read privileges runs an aggregate command that combines these two settings.
CVE-2026-88836
Rejected reason: Red Hat Product Security determined this is not a security vulnerability. BusyBox internal TLS is intentionally minimal and documents in FEATURE_WGET_HTTPS that it does not verify peer identity or provide full TLS security; missing Finished verify_data checking is consistent with that documented design and does not cross a separate security boundary warranting a CVE.
