CVE-2026-53077

A flaw was found in the Linux kernel's Reliable Datagram Sockets over InfiniBand RDS/IB component. This vulnerability allowed the use of RDS/IB in network namespaces other than the initial one, where the existing code would not function correctly. This improper operation could lead to unexpected...

CVE-2026-52995

A flaw was found in the Linux kernel's Reliable Datagram Sockets RDS subsystem. This vulnerability allows a local unprivileged user to disclose sensitive kernel memory. When a user queries connection information through getsockoptSOLRDS, RDSINFOIBCONNECTIONS while an RDS connection is not fully...

SUSE CVE-2026-53184

In the Linux kernel, the following vulnerability has been resolved: udp: clear skb-dev before running a sockmap verdict On the UDP receive path skb-dev is repurposed as devscratch the truesize/state cache set by udpsetdevscratch, through the union struct netdevice dev; unsigned long devscratch; i...

Name of the Vulnerable Software and Affected Versions Envoy versions prior to 1.35.11 Envoy versions prior to 1.36.7 Envoy versions prior to 1.37.3 Envoy versions prior to 1.38.1 Description An issue exists in the UDP DNS filter when configured with local or remote resolution for names exactly 25...

CVE-2026-53070

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP over User Datagram Protocol UDP implementation. An issue with managing the transmission context across different processing units could lead to incorrect recursion level detection. This can cause network packets to b...

CVE-2026-6679

A heap buffer overflow could occur in the DTLS 1.3 ACK serialization path before the connecting peer is authenticated. The buffer overflow was due to an integer truncation when computing the length of the ACK record-number list, causing an undersized buffer to be allocated and then overrun. This...

gnutls: GnuTLS: Denial of Service via heap buffer overflow in DTLS handshake fragment reassembly

A heap buffer overflow vulnerability exists in the DTLS handshake fragment reassembly logic of GnuTLS. The issue arises in mergehandshakepacket where incoming handshake fragments are matched and merged based solely on handshake type, without validating that the messagelength field remains...

gnutls: gnutls: Denial of Service via DTLS packet reordering vulnerability

A flaw was found in gnutls. A remote attacker could exploit an issue in the Datagram Transport Layer Security DTLS packet reordering logic. The comparator function, responsible for ordering DTLS packets by sequence numbers, did not correctly handle packets with duplicate sequence numbers. This...

CVE-2026-53151

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix the ACK parser to extract the SACK table for parsing Fix modification of the received skbuff in rxrpcinputsoftacks and a potential incorrect access of the buffer in a fragmented UDP packet the packet would probably hav...

CVE-2026-53184

In the Linux kernel, the following vulnerability has been resolved: udp: clear skb-dev before running a sockmap verdict On the UDP receive path skb-dev is repurposed as devscratch the truesize/state cache set by udpsetdevscratch, through the union struct netdevice dev; unsigned long devscratch; i...

CVE-2026-53184

The CVE-2026-53184 issue affects the Linux kernel UDP sockmap path. On UDP receive, skb->dev is repurposed as dev_scratch; when a SK_SKB verdict program uses BPF socket-lookup helpers (bpf_sk_lookup_tcp/udp, bpf_skc_lookup_tcp), skb->dev may still hold the dev_scratch value, and dev_net(skb...
