CVE-2026-58268

SIPGO is a library for writing SIP services in the GO language. Prior to 1.4.1, ParserStream.parseSingle in sip/parserstream.go allocates a SIP body buffer from the client-controlled Content-Length header before ParseMaxMessageLength is enforced. An unauthenticated peer can send a stream-transpor...

CVE-2026-16512 Out-of-bounds read in the Zephyr gPTP receive path when handling short Ethernet frames

gptphandlemsg in subsys/net/l2/ethernet/gptp/gptp.c dereferenced the gPTP header returned by GPTPHDR and switched on hdr-messagetype without first checking that the received frame carries at least sizeofstruct gptphdr 34 bytes of payload. The header accessor gptpgethdr deliberately never fails fo...

CVE-2026-80789

In the Linux kernel nvmet-tcp component (NVMe/TCP target), a host-controlled 32-bit sgl->length field is only validated for in-capsule SGL descriptors. Non-inline transport SGL data-block descriptors—those used for out-of-capsule writes—skip the check entirely, causing an unbounded sgl_alloc()...

CVE-2026-75538 A Signed Length Overflow in Erlang/OTP's inet TCP Driver Overflows the Receive Buffer Into BEAM VM Memory From an Unauthenticated Peer

An attacker that connects to an open Erlang TCP port that uses the inet driver with packet,4 mode can use a signed overflow in an incorrect packet length calculation to overflow the receive buffer into the VM allocator area and beyond up to about 2 GB. This would easily trash the allocated block'...

CVE-2026-52829

ZEBRA is a Zcash node written entirely in Rust. Prior to 4.5.0, an unauthenticated IPv4 peer can deterministically terminate a synced Zebra node using the default Linux dual-stack listener configuration. The handshake path canonicalized an IPv4-mapped IPv6 PeerSocketAddr such as ::ffff:127.0.0.1 ...

CVE-2026-52829 ZEBRA: IPv4-Mapped Mempool Misbehavior Update Aborts Zebra Address Book

ZEBRA is a Zcash node written entirely in Rust. Prior to 4.5.0, an unauthenticated IPv4 peer can deterministically terminate a synced Zebra node using the default Linux dual-stack listener configuration. The handshake path canonicalized an IPv4-mapped IPv6 PeerSocketAddr such as ::ffff:127.0.0.1 ...

CVE-2026-52737 ZEBRA: Sync restart poisoning from single unauthenticated peer via above-lookahead block

ZEBRA is a Zcash node written entirely in Rust. Prior to 4.5.0, a malicious unauthenticated P2P peer can answer Zebra's outbound getblocks or FindBlocks request with a small two-hash inventory and then serve a syntactically valid block whose coinbase height is far above the local chain tip. In...

CVE-2026-56818 Netty: RedisArrayAggregator max-elements failure leaves retained partial aggregate state

Netty is an asynchronous, event-driven network application framework. Prior to 4.1.136.Final and 4.2.16.Final, the RedisArrayAggregator Redis codec clears retained partial aggregate state when the maxNestedArrayDepth limit is exceeded, but it does not clear the same state when the sibling...

GHSA-93WV-JW9V-4972 Netty: HTTP/2 decompression leaks ByteBuf reference count when the decompressor channel is already closed (Direct memory leak / OOM DoS)

Summary A remote, unauthenticated peer can leak one direct ByteBuf per HTTP/2 DATA frame in applications that enable HTTP/2 content decompression via DelegatingDecompressorFrameListener. When a DATA frame is processed for a stream whose decompressor has already been closed,...

CVE-2026-10680

The Classic BR/EDR L2CAP signaling handlers l2capbrconfreq and l2capbrconfrsp in subsys/bluetooth/host/classic/l2capbr.c validated the minimum command size against buf-len the bytes remaining in the whole received PDU instead of len the per-command data length from the L2CAP signaling header...

CVE-2026-10680

CVE-2026-10680 affects Zephyr Project’s Classic BR/EDR L2CAP signaling: l2cap_br_conf_req() and l2cap_br_conf_rsp() validate the per-command length against the whole PDU length (buf->len) instead of the per-command len, allowing underflow of opt_len and an out-of-bounds read/write during confi...
