| CVE-2026-20082 | Hig | 0.56 | 8.6 | 0.00 | Mar 4, 2026 | A vulnerability in the handling of the embryonic connection limits in Cisco Secure Firewall Adaptive Security Appliance (ASA) Software could allow an unauthenticated, remote attacker to cause incoming TCP SYN packets to be dropped incorrectly. This vulnerability is due to improper handling of new, incoming TCP connections that are destined to management or data interfaces when the device is under a TCP SYN flood attack. An attacker could exploit this vulnerability by sending a crafted stream of traffic to an affected device. A successful exploit could allow the attacker to prevent all incoming TCP connections to the device from being established, including remote management access, Remote Access VPN (RAVPN) connections, and all network protocols that are TCP-based. This results in a denial of service (DoS) condition for affected features. | |
| CVE-2001-0830 | Hig | 0.52 | 7.5 | 0.09 | Dec 6, 2001 | 6tunnel 0.08 and earlier does not properly close sockets that were initiated by a client, which allows remote attackers to cause a denial of service (resource exhaustion) by repeatedly connecting to and disconnecting from the server. | |
| CVE-1999-1127 | Hig | 0.51 | 7.5 | 0.30 | Dec 31, 1999 | Windows NT 4.0 does not properly shut down invalid named pipe RPC connections, which allows remote attackers to cause a denial of service (resource exhaustion) via a series of connections containing malformed data, aka the "Named Pipes Over RPC" vulnerability. | |
| CVE-2025-65947 | Hig | 0.50 | — | 0.00 | Nov 21, 2025 | thread-amount is a tool that gets the amount of threads in the current process. Prior to version 0.2.2, there are resource leaks when querying thread counts on Windows and Apple platforms. In Windows platforms, the thread_amount function calls CreateToolhelp32Snapshot but fails to close the returned HANDLE using CloseHandle. Repeated calls to this function will cause the handle count of the process to grow indefinitely, eventually leading to system instability or process termination when the handle limit is reached. In Apple platforms, the thread_amount function calls task_threads (via Mach kernel APIs) which allocates memory for the thread list. The function fails to deallocate this memory using vm_deallocate. Repeated calls will result in a steady memory leak, eventually causing the process to be killed by the OOM (Out of Memory) killer. This issue has been patched in version 0.2.2. | |
| CVE-2025-24120 | Hig | 0.49 | 7.5 | 0.00 | Jan 27, 2025 | This issue was addressed by improved management of object lifetimes. This issue is fixed in macOS Sequoia 15.3, macOS Sonoma 14.7.3, macOS Ventura 13.7.3. An attacker may be able to cause unexpected app termination. | |

| CVE-2008-2122 | Hig | 0.49 | 7.5 | 0.05 | May 9, 2008 | IBM Rational Build Forge 7.0.2 allows remote attackers to cause a denial of service (CPU consumption) via a port scan, which spawns multiple bfagent server processes that attempt to read data from closed sockets. | |
| CVE-2007-4103 | Hig | 0.49 | 7.5 | 0.03 | Jul 31, 2007 | The IAX2 channel driver (chan_iax2) in Asterisk Open 1.2.x before 1.2.23, 1.4.x before 1.4.9, and Asterisk Appliance Developer Kit before 0.6.0, when configured to allow unauthenticated calls, allows remote attackers to cause a denial of service (resource exhaustion) via a flood of calls that do not complete a 3-way handshake, which causes an ast_channel to be allocated but not released. | |
| CVE-2007-0897 | Hig | 0.49 | 7.5 | 0.08 | Feb 16, 2007 | Clam AntiVirus ClamAV before 0.90 does not close open file descriptors under certain conditions, which allows remote attackers to cause a denial of service (file descriptor consumption and failed scans) via CAB archives with a cabinet header record length of zero, which causes a function to return without closing a file descriptor. | |
| CVE-2025-27421 | Hig | 0.42 | 7.5 | 0.00 | Mar 3, 2025 | Abacus is a highly scalable and stateless counting API. A critical goroutine leak vulnerability has been identified in the Abacus server's Server-Sent Events (SSE) implementation. The issue occurs when clients disconnect from the /stream endpoint, as the server fails to properly clean up resources and terminate associated goroutines. This leads to resource exhaustion where the server continues running but eventually stops accepting new SSE connections while maintaining high memory usage. The vulnerability specifically involves improper channel cleanup in the event handling mechanism, causing goroutines to remain blocked indefinitely. This vulnerability is fixed in 1.4.0. | |

| CVE-2024-1300 | Med | 0.28 | 5.4 | 0.00 | Apr 2, 2024 | A vulnerability in the Eclipse Vert.x toolkit causes a memory leak in TCP servers configured with TLS and SNI support. When processing an unknown SNI server name assigned the default certificate instead of a mapped certificate, the SSL context is erroneously cached in the server name map, leading to memory exhaustion. This flaw allows attackers to send TLS client hello messages with fake server names, triggering a JVM out-of-memory error. | |
| CVE-2023-32255 | Med | 0.27 | 5.3 | 0.00 | Aug 2, 2025 | A flaw was found in the Linux kernel's ksmbd component. A memory leak can occur if a client sends a session setup request with an unknown NTLMSSP message type, potentially leading to resource exhaustion. | |
