CVE-2026-19446

IBM AIX 7.2/7.3 and PowerVM VIOS 4.1 are vulnerable: a remote unauthenticated attacker can crash a reachable RPC service via a crafted UDP packet, causing complete system unavailability requiring an LPAR restart (CVSS 7.5 HIGH). No patch version or exploit details are provided in the documents; e...

CVE-2026-74283

A flaw was found in the Linux kernel's Transparent Inter-Process Communication TIPC version 2 component. This vulnerability allows a local unprivileged attacker to bypass administrative permission checks when performing network link operations. Consequently, the attacker can modify critical TIPC...

DEBIAN-CVE-2026-68554

Coturn is a free open source implementation of TURN and STUN Server. Prior to 4.15.0, an on-path attacker can append attributes after MESSAGE-INTEGRITY to an authenticated STUN request on plain UDP or TCP, adjust the STUN header length, and recompute the unkeyed FINGERPRINT while the original HMA...

CVE-2026-72404

A flaw was found in the Linux kernel's TIPC UDP media bearer. This vulnerability, a Use-After-Free UAF condition, occurs because certain data structures are prematurely destroyed during teardown without proper synchronization with concurrent operations. A local attacker with network access could...

CVE-2026-72405

A flaw was found in the Linux kernel's UDP tunnel networking component. A race condition in the udptunnelnicdevicesync function allows a work item to be double-queued. This can lead to a use-after-free vulnerability, where memory is prematurely freed while still active. A local attacker could...

GO-2026-6237 Denial of service via malformed IPv4 packet in github.com/insomniacslk/dhcp

In github.com/insomniacslk/dhcp/dhcpv4/nclient4, BroadcastRawUDPConn.ReadFrom does not validate that the IPv4 payload length is sufficient to hold a UDP header before calculating the DHCP payload length. A frame with an IPv4 total-length field specifying fewer than eight payload bytes results in ...

CVE-2026-50252
