CVE-2026-13481

CVE-2026-13481 is an out-of-bounds read in the IEEE 1588 PTP management-message parser in Zephyr RTOS (subsys/net/lib/ptp/tlv.c). In tlv_mgmt_post_recv(), the PTP_MGMT_TIME case casts TLV data to a 10-byte ptp_timestamp struct without validating that the data field is at least that size, unlike a...

EUVD-2026-66556

The LoRaWAN TS004 Fragmented Data Block Transport handler fragtransportpackagecallback in subsys/lorawan/services/fragtransport.c parses downlink command bytes without validating that enough payload bytes remain before each access. The loop's only bound is rxpos fragsize, capped at...

CVE-2026-13480 Out-of-bounds read in LoRaWAN fragmented data block transport (FUOTA) downlink handler

CVE-2026-13480

CVE-2026-13480 is an out-of-bounds read in the Zephyr RTOS LoRaWAN TS004 Fragmented Data Block Transport (FUOTA) downlink handler (frag_transport_package_callback() in subsys/lorawan/services/frag_transport.c). The handler fails to validate remaining payload length before casting to a 10-byte set...

CVE-2026-13479

Zephyr RTOS LoRaWAN clock-synchronization service (subsys/lorawan/services/clock_sync.c) contains an out-of-bounds read in clock_sync_package_callback(). When processing the CLOCK_SYNC_CMD_APP_TIME (AppTimeAns) downlink, the handler reads a 4-byte time correction and a 1-byte token without verify...

EUVD-2026-66555

The LoRaWAN application-layer clock-synchronization service parses downlinks in clocksyncpackagecallback subsys/lorawan/services/clocksync.c. Its command loop only guarantees that the one-byte command id is in bounds; for the CLOCKSYNCCMDAPPTIME AppTimeAns command the handler then reads a 4-byte...

crypto/x509: golang: golang crypto/x509: Denial of Service via excessive processing of DNS SAN entries

A flaw was found in the crypto/x509 package of golang. This vulnerability allows a remote attacker to cause a Denial of Service DoS by presenting a specially crafted X.509 certificate with a large number of DNS Subject Alternative Name SAN entries. The certificate verification process, specifical...

net/http: golang: Go net/http: Unencrypted HTTP/2 connections vulnerable to Denial of Service

A flaw was found in the net/http component of the Go standard library. When a server is configured to support unencrypted HTTP/2, it reads initial bytes from new connections to detect the HTTP/2 client preface. However, the ReadHeaderTimeout is not correctly applied during this process. This...

net/url: golang: golang net/url: Denial of Service from quadratic complexity in path resolution

A flaw was found in net/url, a component of golang. This vulnerability arises when resolving relative paths that contain numerous parent directory '..' segments. A remote attacker could exploit this by providing a specially crafted path, leading to quadratic time complexity and excessive memory...

encoding/xml: golang: Go: Denial of Service via XML decoding recursion depth issue

A flaw was found in the encoding/xml package of Go. The DecodeElement function failed to correctly track recursion depth, which could lead to stack exhaustion. A remote attacker could exploit this vulnerability by providing a specially crafted XML input, resulting in a Denial of Service DoS for t...

Important: Red Hat Security Advisory: golang security, bug fix, and enhancement update

An update for golang is now available for Red Hat Enterprise Linux 10. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from t...

encoding/asn1: golang: Go encoding/asn1: Denial of Service via excessive recursion in Unmarshal

A flaw was found in the encoding/asn1 package in Go. An attacker could provide a specially crafted, deeply-nested Abstract Syntax Notation One ASN.1 structure, leading to excessive recursion during the Unmarshal operation. This could result in stack exhaustion and a Denial of Service DoS conditio...

crypto/tls: golang: Golang crypto/tls: Denial of Service via indefinite KeyUpdate messages

A flaw was found in the crypto/tls package, part of golang. A malicious client can exploit this vulnerability by continuously sending KeyUpdate messages to a server. This forces the server to perform indefinite key derivation operations, leading to resource exhaustion and a Denial of Service DoS...
