Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read in the GOAWAY frame parsing process. An attacker can cause the application to read past the end of a heap buffer by sending a specially crafted HTTP/2 GOAWAY frame lacking a proper null terminator, which may result in...

kernel: KVM: x86: Fix shadow paging use-after-free due to unexpected GFN

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine x86 shadow paging mechanism. This use-after-free vulnerability arises from incorrect handling of Guest Frame Numbers GFNs when guest page tables are modified. A local attacker with control over a guest virtual machine could...

EUVD-2026-43607

OpENer 2.3.0 commit 76b95cf has an out-of-bounds read issue in CIP message parsing when handling malformed explicit requests with a forged EPath size. An attacker can send a valid ENIP SendRRData frame carrying a very short CIP payload whose pathsize field claims that many more path words are...

Name of the Vulnerable Software and Affected Versions Netty versions 4.1.0.Final through 4.1.135.Final Netty versions 4.2.0.Final through 4.2.15.Final Description A remote unauthenticated peer can cause a memory leak of one direct ByteBuf per HTTP/2 DATA frame in applications that enable HTTP/2...

CVE-2026-15712: Out-of-bounds Read

A heap buffer over-read vulnerability was discovered in libsoup's HTTP/2 connection tracking framework. When the library processes an HTTP/2 GOAWAY frame, it improperly handles the "Additional Debug Data" payload by assuming the data stream is a safely NUL-terminated C-string. Because the parser...

CVE-2026-12478: Out-of-bounds Read

The fix for CVE-2026-0716 commit 6ff7ef0, libsoup 3.6.6 placed the integer overflow guard inside the if masked block, leaving unmasked server-to-client frames unprotected. A malicious WebSocket server can send a crafted unmasked frame with a payload length near UINT64MAX to trigger an OOB read in...

CVE-2026-15711: Allocation of Resources Without Limits or Throttling

A vulnerability was found in libsoup's WebSocket frame parsing implementation. The library fails to validate length rules specified in RFC 6455 §5.5, which mandates that all WebSocket control frames e.g., PING, PONG, CLOSE contain a payload of 125 bytes or less. A remote, unauthenticated attacker...

binutils: GNU Binutils Linker heap-based overflow

A head based buffer overflow flaw has been discovered in GNU bin utilities. Impacted is the function bfdelfparseehframe of the file bfd/elf-eh-frame.c of the component Linker. Executing manipulation can lead to heap-based buffer overflow. The attack is restricted to local execution...

PYSEC-2026-3406 vLLM: image EXIF Rotation & PNG tRNS Transparency Not Normalized, Causing Mismatch Between Model Input and Expectations

Summary Issue 1: EXIF orientation not normalized → The image orientation processed by the model differs from how humans view it, introducing interpretation bias. Issue 2: PNG tRNS not explicitly flattened before converting to RGB → After conversion, transparent/semi-transparent pixels are rendere...

PYSEC-2026-3386 Denial of service via non-terminating SYLT frame parsing loop in tinytag

Summary tinytag 2.2.0 allows an attacker who can supply MP3 files for parsing to trigger a non-terminating loop while the library parses an ID3v2 SYLT synchronized lyrics frame. In server-side deployments that automatically parse attacker-supplied files, a single 498-byte MP3 can cause the parsin...

undici: undici: Denial of Service due to unbounded memory growth via WebSocket frames

A flaw was found in undici. A malicious WebSocket server can exploit this by streaming numerous small or empty continuation frames. This can bypass per-frame and cumulative-size validation, leading to unbounded memory growth in the client process. The primary consequence is memory exhaustion,...

CVE-2026-57220

RabbitMQ is a messaging and streaming broker. Prior to 4.2.6, the RabbitMQ stream listener does not enforce the configured stream frame-size limit while assembling frames during authentication and before Tune negotiation, allowing an unauthenticated remote client to declare oversized frame length...
