• Project: Go Core Image Packages (golang.org/x/image/tiff)
• Vulnerability: Unbounded Memory Allocation / Resource Exhaustion - CVSS 7.5
• Official Advisory: GO-2026-5062 | GHSA-pwfv-328h-75x9
• Impact: Identified a resource validation flaw where processing maliciously crafted tiled TIFF images forces immediate Out of Memory (OOM) errors and Denial of Service (DoS).

• Project: Google go-attestation Library
• Vulnerability: Improper Input Validation / TPM Hash Injection - CVSS 8.9
• Official Advisory: GHSA-9r4w-jg96-92mv
• Impact: Discovered a critical logic flaw in parseEfiSignatureList() where a crafted TPM event log can inject arbitrary SHA256 hashes into a verifier's trusted database, causing a compromised boot state to be falsely accepted.

• Project: Percona Monitoring and Management (PMM)
• Vulnerability: Authenticated Remote Code Execution (RCE) - CVSS 9.9
• Official Advisory: GHSA-hm6f-x2ww-p497
• Impact: Identified a critical flaw allowing full host compromise via reverse shell.

• Project: Google Project Oak
• Vulnerability: Trusted Execution Environment (TEE) Attestation Bypass
• Official Advisory: GHSA-3238-pp48-6m3j
• Impact: Discovered a critical validation flaw enabling a complete bypass of enclave security measurements, allowing untrusted hosts to spoof remote attestation states.

• Project: MLflow (mlflow/mlflow)
• Vulnerability: Path Traversal / Arbitrary File Read
• Official Advisory: GHSA-gqvg-gmmx-x4hm
• Impact: Discovered a path traversal flaw in MLflow artifact retrieval endpoints. An attacker could manipulate URI path parameters to bypass directory containment and read arbitrary files directly from the underlying server filesystem.

• Project: Google Project Oak (project-oak/oak)
• Vulnerability: Stage0 Firmware Integer Overflow / Memory Corruption
• Official Advisory: GHSA-pj9q-pv45-xq8g
• Impact: Discovered an integer overflow in the setup_high_allocator function within the stage0 bootloader firmware. An untrusted host or hypervisor could supply a maliciously crafted E820 memory map entry to trigger silent memory aliasing during heap initialization, leading to enclave memory corruption.

• Project: OpenXLA & TensorFlow (openxla/xla / tensorflow/tensorflow)
• Vulnerability: Integer Overflow / Out-of-Bounds Memory Access
• Official Advisory: OpenXLA PR #46403 | OpenXLA PR #46495 | TensorFlow PR #124350
• Impact: Discovered an integer overflow vulnerability in Shape::FromProto shape deserialization logic. Processing malformed proto definitions with oversized array bounds could bypass shape validation, leading to out-of-bounds memory access, heap corruption, or runtime crashes across OpenXLA and TensorFlow graph compilers.

• Project: Google XNNPACK (google/XNNPACK)
• Vulnerability: Integer Overflow / Heap-based Buffer Overflow
• Official Advisory: Pull Request #10842
• Impact: Discovered an integer overflow vulnerability in the batch matrix multiplication operator when calculating packed weights allocation size. An attacker supplying oversized, caller-controlled tensor dimensions through public API calls could trigger heap memory corruption or runtime crashes.

• Project: OpenXLA Compiler (openxla/xla)
• Vulnerability: Out-of-Bounds Memory Access / Improper Input Validation
• Official Advisory: Pull Request #46105
• Impact: Discovered a validation vulnerability in BufferAssignment::FromProto where assigned buffer allocation offsets and sizes were deserialized without verifying boundary limits. Loading malformed or untrusted HLO proto definitions allowed unvalidated offsets to trigger out-of-bounds memory access, heap corruption, or unexpected compiler crashes.

• Project: Google XNNPACK (google/XNNPACK)
• Vulnerability: Integer Overflow / Heap-based Buffer Overflow
• Official Advisory: Pull Request #10834
• Impact: Identified an integer overflow flaw during kernel-size dimension calculations in the deconvolution operator. Processing maliciously crafted layer parameters bypassed spatial memory bounds, leading to heap buffer overflows and unexpected memory corruption.

• Project: Go Extended Cryptography Library (golang/go / x/crypto)
• Vulnerability: Cryptographic Parameter Validation Bypass / Improper Input Validation
• Official Advisory: Issue #80418
• Impact: Discovered a vulnerability in the ssh.ParseDSAPrivateKey() function where ASN.1 DER-encoded DSA private keys are processed without verifying the mathematical validity of their core cryptographic parameters (p, q, and g). An application parsing a maliciously structured or malformed private key could be forced into intense CPU exhaustion (Denial of Service), trigger runtime panics, or experience unpredictable cryptographic failures during signature and verification operations.

• Project: Go Extended Cryptography Library (golang/go / x/crypto)
• Vulnerability: Improper Input Sanitization / ANSI Escape Sequence Injection
• Official Advisory: Issue #80302
• Impact: Discovered a vulnerability in the ssh.BannerDisplayStderr() helper function where pre-authentication SSH banners were streamed directly to os.Stderr without data sanitization. A malicious or compromised server could inject arbitrary ANSI escape codes to execute terminal spoofing, manipulate clipboards, or potentially exploit underlying terminal emulator vulnerabilities on the client side.

• Project: Google gVisor Container Sandbox (google/gvisor)
• Vulnerability: Mount Namespace Security / Container Isolation Bypass
• Official Advisory: Issue #13481 | Pull Request #13482
• Impact: Discovered a sandbox isolation flaw where open_tree(OPEN_TREE_CLONE) incorrectly succeeded on MNT_DETACH unmounted paths (which strictly returns EINVAL on native Linux). This allowed a user with container root privileges to clone and re-attach an intentionally isolated filesystem via move_mount(2), completely breaking container containment boundaries.

• Project: Trezor Blockbook Service
• Vulnerability: Unauthenticated Resource Exhaustion (DoS)
• Official Advisory: Trezor Security
• Impact: Identified an amplification flaw where uncapped change indexes in xpub descriptors forced excessive database lookups and address derivations, filling a global in-memory cache and forcing a complete Out-of-Memory (OOM) server crash.

• Project: Trezor Blockbook Service
• Vulnerability: Denial of Service (DoS) via Unbounded Timestamp Array
• Official Advisory: Trezor Security
• Impact: Found a flaw in the historical price API allowing unauthenticated remote attackers to pass massive, unbounded timestamp arrays to trigger rapid server memory exhaustion.

• Project: PowerDNS dnsdist
• Vulnerability: Logic Flaw / Denial of Service (DoS) Mitigation Bypass
• Official Advisory: Pull Request #17287
• Impact: Discovered a critical logic error in bpf-filter.cc where range-based subnet evaluation queries incorrectly triggered a runtime error, completely breaking active eBPF-based blocking mechanisms and leaving the DNS infrastructure exposed during traffic spikes.

• Project: PowerDNS dnsdist
• Vulnerability: Authorization Bypass / Improper Access Control
• Official Advisory: Pull Request #17291
• Impact: Identified a security boundary issue where restricted "Read-Only" API tokens could bypass endpoint separation rules to execute unintended state-changing memory actions (such as purging the global packet cache and exploiting CORS misconfigurations), breaking the isolation between read and write access keys.
