CVE-2026-53228

A flaw was found in the Linux kernel's Simple Internet Transition SIT tunnel driver for IPv6. When processing network traffic with Generic Segmentation Offload GSO enabled, the driver may use a stale pointer to the inner IPv6 header after the socket buffer skb head has been reallocated. This can...

CVE-2026-47220

The CVE describes a crash in Envoy when using %REQUESTED_SERVER_NAME(X:Y)% in log format with host-related options (e.g., HOST_FIRST, SNI_FIRST) and the specified host header is missing in the request headers. Affected versions are 1.37.0 through 1.37.5 and 1.38.3. The vulnerability arises from t...

CVE-2026-47220 Envoy: Segmentation fault when using %REQUESTED_SERVER_NAME% in log format

Envoy is an open source edge and service proxy designed for cloud-native applications. From 1.37.0 until 1.37.5 and 1.38.3, when the %REQUESTEDSERVERNAMEX:Y% is used in log format and host related options is specified, like HOSTFIRST, SNIFIRST, it's possible to crash Envoy when the specified host...

CVE-2026-47205

CVE-2026-47205 affects Envoy’s ext_authz HTTP filter. From 1.36.0 through 1.36.9, 1.37.5, and 1.38.3, a Use-After-Free (UAF) occurs when processing per-route authorization overrides concurrently with rapid downstream disconnects. The vulnerable flow creates a transient per-route client and reallo...

CVE-2026-53091

A flaw was found in the Linux kernel's handling of Generic Segmentation Offload GSO packet headers. This vulnerability occurs when the qdiscpktlensegsinit function does not properly pull headers into the expected memory location, which can lead to incorrect processing by network drivers. A remote...
