| CVE-2020-15294 | Compiler Optimization Removal or Modification of Security-critical Code vulnerability in IntPeParseUnwindData() results in multiple dereferences to the same pointer. If the pointer is located in memory-mapped from the guest space, this may cause a race-condition where the generated code would dereference the same address twice, thus obtaining different values, which may lead to arbitrary code execution. This issue affects: Bitdefender Hypervisor Introspection versions prior to 1.132.2. | HIGH7.0 | 0.29%p21 | 2026-06-17 | |
| CVE-2025-20241 | A vulnerability in the Intermediate System-to-Intermediate System (IS-IS) feature of Cisco NX-OS Software for Cisco Nexus 3000 Series Switches and Cisco Nexus 9000 Series Switches in standalone NX-OS mode could allow an unauthenticated, adjacent attacker to cause the IS-IS process to unexpectedly restart, which could cause an affected device to reload. This vulnerability is due to insufficient input validation when parsing an ingress IS-IS packet. An attacker could exploit this vulnerability by sending a crafted IS-IS packet to an affected device. A successful exploit could allow the attacker to cause the unexpected restart of the IS-IS process, which could cause the affected device to reload, resulting in a denial of service (DoS) condition. Note: The IS-IS protocol is a routing protocol. To exploit this vulnerability, an attacker must be Layer 2-adjacent to the affected device. | HIGH7.4 | 0.27%p19 | 2026-06-17 | |
| CVE-2025-52496 | Mbed TLS before 3.6.4 has a race condition in AESNI detection if certain compiler optimizations occur. An attacker may be able to extract an AES key from a multithreaded program, or perform a GCM forgery. | HIGH7.8 | 0.19%p9 | 2026-06-17 | |
| CVE-2024-58262 | The curve25519-dalek crate before 4.1.3 for Rust has a constant-time operation on elliptic curve scalars that is removed by LLVM. | MEDIUM5.1 | 0.15%p5 | 2026-06-17 |
