CVE-2024-22383 1 Gallagher 1 Controller 7000 2026-04-15 6.2 Medium
Missing release of resource after effective lifetime (CWE-772) in the Controller 7000 resulted in HBUS connected T-Series readers to not automatically recover after coming under attack over the RS-485 interface, resulting in a persistent denial of service. This issue affects: All variants of the Gallagher Controller 7000 9.00 prior to vCR9.00.231204b (distributed in 9.00.1507(MR1)), 8.90 prior to vCR8.90.240209b (distributed in 8.90.1751 (MR3)), 8.80 prior to vCR8.80.240209a (distributed in 8.80.1526 (MR4)), 8.70 prior to vCR8.70.240209a (distributed in 8.70.2526 (MR6)).
CVE-2025-14969 1 Redhat 4 Jboss Enterprise Application Platform, Jbosseapxp, Openshift Devspaces and 1 more 2026-04-15 4.3 Medium
A flaw was found in Hibernate Reactive. When an HTTP endpoint is exposed to perform database operations, a remote client can prematurely close the HTTP connection. This action may lead to leaking connections from the database connection pool, potentially causing a Denial of Service (DoS) by exhausting available database connections.
CVE-2025-65947 1 Thread-amount Project 1 Thread-amount 2026-04-15 N/A
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-2025-3864 2026-04-15 N/A
Hackney fails to properly release HTTP connections to the pool after handling 307 Temporary Redirect responses. Remote attackers can exploit this to exhaust connection pools, causing denial of service in applications using the library. Fix for this issue has been included in 1.24.0 release.
CVE-2025-64734 1 Gallagher 1 Command Centre 2026-04-15 2.4 Low
Missing Release of Resource after Effective Lifetime (CWE-772) in the T21 Reader allows an attacker with physical access to the Reader to perform a denial-of-service attack against that specific reader, preventing cardholders from badging for entry. This issue affects Command Centre Server: 9.30 prior to vCR9.30.251028a (distributed in 9.30.2881 (MR3)), 9.20 prior to vCR9.20.251028a (distributed in 9.20.3265 (MR5)), 9.10 prior to vCR9.10.251028a (distributed in 9.10.4135 (MR8)),  all versions of 9.00 and prior.
CVE-2025-27421 2026-04-15 7.5 High
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-2023-32255 1 Redhat 1 Enterprise Linux 2026-04-15 5.3 Medium
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.
CVE-2026-23320 1 Linux 1 Linux Kernel 2026-04-03 7.0 High
This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.
CVE-2026-21714 1 Nodejs 1 Nodejs 2026-04-02 5.3 Medium
A memory leak occurs in Node.js HTTP/2 servers when a client sends WINDOW_UPDATE frames on stream 0 (connection-level) that cause the flow control window to exceed the maximum value of 2³¹-1. The server correctly sends a GOAWAY frame, but the Http2Session object is never cleaned up. This vulnerability affects HTTP2 users on Node.js 20, 22, 24 and 25.
CVE-2026-32874 2 Ultrajson, Ultrajson Project 2 Ultrajson, Ultrajson 2026-03-25 7.5 High
UltraJSON is a fast JSON encoder and decoder written in pure C with bindings for Python 3.7+. Versions 5.4.0 through 5.11.0 contain an accumulating memory leak in JSON parsing large (outside of the range [-2^63, 2^64 - 1]) integers. The leaked memory is a copy of the string form of the integer plus an additional NULL byte. The leak occurs irrespective of whether the integer parses successfully or is rejected due to having more than sys.get_int_max_str_digits() digits, meaning that any sized leak per malicious JSON can be achieved provided that there is no limit on the overall size of the payload. Any service that calls ujson.load()/ujson.loads()/ujson.decode() on untrusted inputs is affected and vulnerable to denial of service attacks. This issue has been fixed in version 5.12.0.
CVE-2026-30873 1 Openwrt 1 Openwrt 2026-03-25 4.9 Medium
OpenWrt Project is a Linux operating system targeting embedded devices. In versions prior to both 24.10.6 and 25.12.1, the jp_get_token function, which performs lexical analysis by breaking input expressions into tokens, contains a memory leak vulnerability when extracting string literals, field labels, and regular expressions using dynamic memory allocation. These extracted results are stored in a jp_opcode struct, which is later copied to a newly allocated jp_opcode object via jp_alloc_op. During this transfer, if a string was previously extracted and stored in the initial jp_opcode, it is copied to the new allocation but the original memory is never freed, resulting in a memory leak. This issue has been fixed in versions 24.10.6 and 25.12.1.
CVE-2020-9375 1 Tp-link 2 Archer C5, Archer C50 2026-03-05 7.5 High
TP-Link Archer C50 V3 devices before Build 200318 Rel. 62209 allows remote attackers to cause a denial of service via a crafted HTTP Header containing an unexpected Referer field.
CVE-2025-66560 1 Quarkus 1 Quarkus 2026-02-03 5.9 Medium
Quarkus is a Cloud Native, (Linux) Container First framework for writing Java applications. Prior to versions 3.31.0, 3.27.2, and 3.20.5, a vulnerability exists in the HTTP layer of Quarkus REST related to response handling. When a response is being written, the framework waits for previously written response chunks to be fully transmitted before proceeding. If the client connection is dropped during this waiting period, the associated worker thread is never released and becomes permanently blocked. Under sustained or repeated occurrences, this can exhaust the available worker threads, leading to degraded performance, or complete unavailability of the application. This issue has been patched in versions 3.31.0, 3.27.2, and 3.20.5. A workaround involves implementing a health check that monitors the status and saturation of the worker thread pool to detect abnormal thread retention early.
