| CVE-2026-75371 | 1 Spacedot | 1 Acubesat | 2026-08-26 | 7.5 High |
| An integer handling flaw in the cobs_decode function of SpaceDot AcubeSAT OBC software commit eaf90ec allows physically-proximate attackers with UART access to cause a Denial of Service (DoS) via a crafted input. | ||||
| CVE-2026-12999 | 1 Zephyrproject | 1 Zephyr | 2026-08-25 | 5.3 Medium |
| The Infineon Airoc Wi-Fi driver's transmit callback airoc_mgmt_send() in drivers/wifi/infineon/airoc_wifi.c allocates a net_buf from the fixed airoc_pool for every outbound packet. When whd_network_send_ethernet_data() returns a synchronous failure, the underlying WHD library does not take ownership of the buffer, but the pre-fix driver returned -EIO without releasing it. Each failed transmit therefore permanently leaks one buffer from the pool. airoc_pool is small and fixed (AIROC_WIFI_TX_PACKET_POOL_COUNT + AIROC_WIFI_RX_PACKET_POOL_COUNT, default 20 buffers) and is shared by WHD's whd_host_buffer_get callback for both transmit and receive. Once enough send failures have leaked the pool dry, airoc_wifi_host_buffer_get() returns WHD_BUFFER_ALLOC_FAIL for all subsequent allocations, so both transmit and the WHD-driven receive path fail and Wi-Fi connectivity is lost until the device is rebooted. The leak occurs only on the transmit error path. A Wi-Fi-adjacent attacker can influence the conditions that cause synchronous send failures (for example by deauthenticating/disassociating the station while the local stack continues to attempt transmits), and ordinary transient failures over the device's lifetime accumulate toward the same state. Reliable on-demand triggering is of high complexity and the impact is availability-only, but the resulting denial of service is permanent and non-recoverable without a reboot. The fix releases the buffer with airoc_wifi_buffer_release() on the failure branch, returning it to the pool. The commit also removes a redundant k_sem_give() in airoc_mgmt_disconnect(); because data->sema_common is a binary semaphore (limit 1) the duplicate give merely saturated at 1 and had no security impact. | ||||
| CVE-2026-19446 | 1 Ibm | 3 Aix, Powervm Vios, Vios | 2026-08-25 | 7.5 High |
| IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 allows a remote unauthenticated attacker can send a crafted UDP packet to a reachable RPC service, resulting in complete system unavailability and requiring an LPAR restart. | ||||
| CVE-2026-77384 | 2026-08-25 | 7.5 High | ||
| libp2p is a JavaScript implementation of the libp2p networking stack. Prior to version 4.2.9, the reservation refresh path in reservation-store.ts reuses the same retimeableSignal but unconditionally registers another abort listener on every refresh. As a result, a remote peer can repeatedly send valid RESERVE requests for the same reservation, causing unbounded listener and closure growth in @libp2p/circuit-relay-v2 relay servers and leading to denial of service. This issue is fixed in version 4.2.9. | ||||
| CVE-2026-55531 | 1 Mervinpraison | 1 Praisonai | 2026-08-25 | 6.5 Medium |
| PraisonAI is a multi-agent teams system. Prior to praisonai 4.6.58, the MCP HTTP Stream mcp_post handler creates a new _sessions entry for every initialize request but does not call _cleanup_sessions or enforce a maximum. An unauthenticated caller can exhaust memory. The fix invokes cleanup and limits sessions through PRAISONAI_MCP_MAX_SESSIONS. This issue is fixed in version 4.6.58. | ||||
| CVE-2026-53531 | 1 Erweixin | 1 Ratex | 2026-08-25 | N/A |
| RaTeX is a KaTeX-compatible math rendering engine written in Rust. Prior to version 0.1.11, RaTeX’s recursive-descent parser recurses one (or more) native stack frame per nesting level at `{`, `\left`, `\sqrt{`, `^{`, etc, with no maximum depth limit. A short, ~10 KB input of nested groups overflows the 8 MB main-thread stack and aborts the process. With `panic = "abort"` (`Cargo.toml:48`), and because a Rust stack overflow is always a fatal `SIGABRT` regardless of panic strategy this is an unrecoverable, whole-process denial of service reachable from a single untrusted LaTeX string. Version 0.1.11 fixes the issue. | ||||
| CVE-2026-48050 | 1 Basekick-labs | 1 Arc | 2026-08-25 | 8.2 High |
| Arc is an open, SQL-native time-series database for telemetry. Versions prior to 26.06.1 register Go's `net/http/pprof` handlers at `/debug/pprof/*` via `app.Use(pprof.New())` in `internal/api/server.go`, and `/debug/pprof` is added to `PublicPrefixes` in `cmd/arc/main.go`. The auth middleware short-circuits before the token check on prefix match, so the endpoints are reachable without any authentication. Version 26.06.1 contains a patch. Some workarounds are available. Block `/debug/pprof*` at a reverse proxy / load balancer in front of Arc, restrict Arc's API port to known-trusted networks via firewall rules, and/or patch the running build: comment out `app.Use(pprof.New())` in `internal/api/server.go` and rebuild. | ||||
| CVE-2022-25762 | 3 Apache, Oracle, Redhat | 3 Tomcat, Agile Product Lifecycle Management, Enterprise Linux | 2026-08-25 | 8.6 High |
| If a web application sends a WebSocket message concurrently with the WebSocket connection closing when running on Apache Tomcat 8.5.0 to 8.5.75 or Apache Tomcat 9.0.0.M1 to 9.0.20, it is possible that the application will continue to use the socket after it has been closed. The error handling triggered in this case could cause the a pooled object to be placed in the pool twice. This could result in subsequent connections using the same object concurrently which could result in data being returned to the wrong use and/or other errors. | ||||
| CVE-2020-13934 | 7 Apache, Canonical, Debian and 4 more | 17 Tomcat, Ubuntu Linux, Debian Linux and 14 more | 2026-08-25 | 7.5 High |
| An h2c direct connection to Apache Tomcat 10.0.0-M1 to 10.0.0-M6, 9.0.0.M5 to 9.0.36 and 8.5.1 to 8.5.56 did not release the HTTP/1.1 processor after the upgrade to HTTP/2. If a sufficient number of such requests were made, an OutOfMemoryException could occur leading to a denial of service. | ||||
| CVE-2020-13935 | 8 Apache, Canonical, Debian and 5 more | 23 Tomcat, Ubuntu Linux, Debian Linux and 20 more | 2026-08-25 | 7.5 High |
| The payload length in a WebSocket frame was not correctly validated in Apache Tomcat 10.0.0-M1 to 10.0.0-M6, 9.0.0.M1 to 9.0.36, 8.5.0 to 8.5.56 and 7.0.27 to 7.0.104. Invalid payload lengths could trigger an infinite loop. Multiple requests with invalid payload lengths could lead to a denial of service. | ||||
| CVE-2026-19653 | 1 Ibm | 2 Aix, Vios | 2026-08-25 | 6.5 Medium |
| IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a local attacker to cause a denial of service due to improper handling of memory page table configurations. | ||||
| CVE-2026-74982 | 1 Mozilla | 2 Firefox, Thunderbird | 2026-08-25 | 7.5 High |
| Denial-of-service in the Widget component. This vulnerability was fixed in Firefox 154, Firefox ESR 153.1, Thunderbird 154, and Thunderbird 153.1. | ||||
| CVE-2026-55373 | 2026-08-25 | 6.2 Medium | ||
| OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. Versions prior to 3.2.10, 3.3.12, and 3.4.13 contain an infinite-loop vulnerability in SampleCountChannel. The helper roundListSizeUp() rounds a sample-list size up to the next power of two using repeated unsigned left shifts, which terminates for normal values but fails for UINT_MAX: the sequence reaches 0x80000000, and the next left shift wraps the 32-bit value to 0. Because 0 remains less than UINT_MAX, the loop never progresses and never exits. The bug is reachable through public OpenEXRUtil APIs, either by editing the sample-count buffer through SampleCountChannel::Edit (whose destructor calls endEdit()) or by calling SampleCountChannel::set(x, y, UINT_MAX) on a valid pixel. This issue has been fixed in versions 3.2.10, 3.3.12, and 3.4.13. | ||||
| CVE-2026-18822 | 1 Ibm | 3 Aix, Powervm Vios, Vios | 2026-08-25 | 4.4 Medium |
| IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 could allow a local attacker to cause a denial of service due to uncontrolled resource consumption when parsing directory records. | ||||
| CVE-2026-45186 | 1 Libexpat Project | 1 Libexpat | 2026-08-25 | 2.9 Low |
| In libexpat before 2.8.1, the computational complexity of attribute name collision checks allows a denial of service via moderately sized crafted XML input. | ||||
| CVE-2026-55241 | 1 Bluewave-labs | 1 Checkmate | 2026-08-25 | 7.5 High |
| Checkmate is an open-source, self-hosted tool designed to track and monitor server hardware, uptime, response times, and incidents in real-time with beautiful visualizations. Prior to 3.9.1, the public POST /api/v1/auth/register route in server/src/api/routes/authRoutes.ts passes multipart profileImage uploads through in-memory Multer parsing before registration validation, without file-size, file-count, or MIME-type limits in server/src/api/middleware/upload.ts. An unauthenticated attacker can submit concurrent oversized files that are buffered before invalid registration or invite-token checks reject the request, exhausting memory and crashing or destabilizing the backend. This issue is fixed in version 3.9.1. | ||||
| CVE-2026-74691 | 1 Linux | 1 Linux Kernel | 2026-08-25 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: net: thunderbolt: Tear down DMA paths before stopping the rings tbnet_tear_down() stops both rings and frees their frame buffers before calling tb_xdomain_disable_paths(). tb_ring_stop() zeroes the ring's descriptor base and tbnet_free_buffers() unmaps and frees the pages the frames sit in, so by the time __tb_path_deactivate_hop() polls the hop's 'pending' bit, anything still in flight has nowhere to drain to. The teardown sequence has been in this order since the driver was added. The setup path has not: commit ff7cd07f3064 ("net: thunderbolt: Enable DMA paths only after rings are enabled") moved the path enable to the end of tbnet_connected_work() and documented why: /* Both logins successful so enable the rings, high-speed DMA * paths and start the network device queue. * * Note we enable the DMA paths last to make sure we have primed * the Rx ring before any incoming packets are allowed to * arrive. */ Teardown was never updated to match, so the rings and the paths now come down in the same order they go up instead of in reverse. On an ASMedia ASM4242 host router the 'pending' bit then never clears: every teardown burns the full 500 ms timeout and __tb_path_deactivate_hop() returns -ETIMEDOUT. Raising the timeout to 5 s does not help, so the hop is not slow to drain, it never drains at all. The failure is invisible above the thunderbolt core. __tb_path_deactivate_hops() is void and only calls tb_port_warn(); tb_path_deactivate(), tb_tunnel_deactivate() and __tb_disconnect_xdomain_paths() are void as well, and tb_disconnect_xdomain_paths() ends in an unconditional "return 0". So tb_xdomain_disable_paths() reports success and the netdev_warn() below it never fires. Repeated teardowns eventually take the XDomain control channel down, after which the peer node is gone and only a power cycle brings the controller back. Deactivating the paths first fixes it. Measured with kretprobes on a stock v6.17 tree with no other patches applied, on a link that was up and had just carried traffic: before: __tb_path_deactivate_hop() returns 0 for the first hop, then -ETIMEDOUT for the second 500335 us later after: 0 for both, 525 us apart Alternating the two orderings ABBA over three load levels, four teardowns per arm: every teardown failed before the change (21 of 21 that ran), none failed after (0 of 24). The before arms ran short because the link died partway through. The same split shows up when the interface is enslaved to a bond instead of just brought down, which is how I ran into this in the first place. Throughput and latency after the change are unchanged. Hosts whose routers drain the hop despite the stale descriptor base see no functional difference, since the paths end up deactivated either way. | ||||
| CVE-2026-76235 | 1 Redhat | 3 Enterprise Linux, Openshift Dev Spaces, Openshift Devspaces | 2026-08-25 | 7.5 High |
| A memory leak flaw was found in cockpit-ws. The login page handler leaks a heap allocation on every unauthenticated request that carries a CockpitLang cookie, allowing a remote unauthenticated attacker to exhaust memory on the host and cause a denial of service. | ||||
| CVE-2026-76014 | 1 Busybox | 1 Busybox | 2026-08-25 | 3.3 Low |
| A vulnerability has been found in BusyBox up to 1.30.1. This vulnerability affects unknown code of the file networking/wget.c of the component FEATURE_WGET_TIMEOUT Handler. Such manipulation of the argument -T leads to null pointer dereference. Local access is required to approach this attack. The exploit has been disclosed to the public and may be used. The name of the patch is 83a40bf7a93c8ac093d33ab452222dd5b9eb57ff. A patch should be applied to remediate this issue. | ||||
