Dragonfly scheduler v1 and v2 gRPC unauthenticated SSRF via attacker-controlled PeerHost in DownloadTinyFile

Summary The Dragonfly scheduler's v1 gRPC service contains an unauthenticated Server-Side Request Forgery SSRF. When a peer reports a successful download of a TINY task, the scheduler calls Peer.DownloadTinyFile and issues an HTTP GET to a host and port taken verbatim from the attacker-controlled...

CVE-2026-52984

A flaw was found in the Linux kernel's networking scheduler netem. The queue limit check in the netemenqueue function does not properly account for reordered packets, allowing the total queue occupancy to exceed its configured limit. This oversight can lead to a Denial of Service DoS condition,...

CVE-2026-53079

A flaw was found in the Linux kernel's networking scheduler netsched. When the network stack cleans up deferred packet lists, if the root queueing discipline qdisc does not implement the TCQFDEQUEUEDROPS flag, packets intended for release are not freed. This can lead to a memory leak, potentially...

CVE-2026-53270

A flaw was found in the Linux kernel's IP Virtual Server IPVS component. During the ipvseditservice operation, the svc-scheduler pointer is cleared too late when unbinding an old scheduler. This improper handling allows packets to access previously freed scheduler data, leading to a use-after-fre...
