Name of the Vulnerable Software and Affected Versions s2n-quic versions prior to 1.8.2 Description Unbounded memory allocation in the CRYPTO frame reassembler allows an unauthenticated remote actor to cause a denial of service, resulting in degraded availability, by sending crafted QUIC Initial...

Allocation of Resources Without Limits or Throttling

Overview Scriban.Signed is a fast, powerful, safe and lightweight scripting language and engine for .NET, which was primarily developed for text templating with a compatibility mode for parsing liquid templates. Affected versions of this package are vulnerable to Allocation of Resources Without...

EUVD-2026-30138

The Grafana Live push endpoint can be exploited to cause unbounded memory allocation by sending a large or streaming request body, potentially leading to out-of-memory conditions. An authenticated user with access to the Grafana Live API can trigger this issue...

Unity Linux 20.1070e Security Update: netty (UTSA-2026-017795)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-017795 advisory. The ZlibDecoders in Netty 4.1.x before 4.1.46 allow for unbounded memory allocation while decoding a ZlibEncoded byte stream. An attacker could send a large...

GHSA-FPF5-4JW8-67X8 rust-zserio has Unbounded Memory Allocation

Impact When deserializing arrays, strings or bytes blob types zserio first reads the size of the variable, and then allocates sufficient memory to load data. Since the size is always trusted this can be abused by creating a data file with a large size value, causing the zserio runtime to allocate...

CVE-2026-6948

CVE-2026-6948 affects Velociraptor servers prior to version 0.76.4, where the VQLResponse Result-Set Writer can allocate memory unboundedly in the agent control channel. A compromised Velociraptor client can trigger an Out-Of-Memory (OOM) condition, crashing the server by sending crafted messages...

CVE-2026-6948 Unbounded Memory Allocation in VQLResponse Result-Set Writer

Velociraptor versions prior to 0.76.4 contain a resource exhaustion vulnerability in the server's agent control channel. This allows a compromised or rogue Velociraptor client to crash the server via out-of-memory OOM by sending crafted messages through the normal client communication channel...

CVE-2026-21728 Tempo query limit results in unbounded memory allocation

Tempo queries with large limits can cause large memory allocations which can impact the availability of the service, depending on its deployment strategy. Mitigation can be done by setting maxresultlimit in the search config, e.g. to 262144 2^18. Alternatively, automatically restart the service...

Memory Allocation with Excessive Size Value

Overview Affected versions of this package are vulnerable to Memory Allocation with Excessive Size Value via the endpoints.GetSessionCookie function. An attacker can exhaust system memory resources by sending specially crafted requests containing a large cookie chunk count, resulting in unbounded...

CVE-2026-40303 zrok allows unauthenticated DoS via unbounded memory allocation in striped session cookie parsing

zrok is software for sharing web services, files, and network resources. Prior to version 2.0.1, endpoints.GetSessionCookie parses an attacker-supplied cookie chunk count and calls makestring, count with no upper bound before any token validation occurs. The function is reached on every request t...

GHSA-353C-V8X9-V7C3 MCP-Framework: Unbounded memory allocation in readRequestBody allows denial of service via HTTP transport

Summary The readRequestBody function in src/transports/http/server.ts concatenates HTTP request body chunks into a string with no size limit, allowing a remote unauthenticated attacker to crash the server via memory exhaustion with a single large HTTP POST request. Details File:...

CVE-2026-2456

Mattermost is affected by CVE-2026-2456 due to an unbounded memory allocation when handling responses from integration action endpoints. A authenticated attacker can cause server memory exhaustion and a denial of service by having a malicious integration server return an arbitrarily large respons...

CVE-2026-31961

Quill provides simple mac binary signing and notarization from any platform. Quill before version v0.7.1 contains an unbounded memory allocation vulnerability when parsing Mach-O binaries. Exploitation requires that Quill processes an attacker-supplied Mach-O binary, which is most likely in...
