| CVE-2026-6747 | 1 Mozilla | 2 Firefox, Thunderbird | 2026-04-22 | 7.5 High |
| Use-after-free in the WebRTC component. This vulnerability was fixed in Firefox 150, Firefox ESR 140.10, Thunderbird 150, and Thunderbird 140.10. | ||||
| CVE-2026-34772 | 2 Electron, Electronjs | 2 Electron, Electron | 2026-04-22 | 5.8 Medium |
| Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to versions 38.8.6, 39.8.0, 40.7.0, and 41.0.0-beta.8, apps that allow downloads and programmatically destroy sessions may be vulnerable to a use-after-free. If a session is torn down while a native save-file dialog is open for a download, dismissing the dialog dereferences freed memory, which may lead to a crash or memory corruption. Apps that do not destroy sessions at runtime, or that do not permit downloads, are not affected. This issue has been patched in versions 38.8.6, 39.8.0, 40.7.0, and 41.0.0-beta.8. | ||||
| CVE-2026-6746 | 1 Mozilla | 2 Firefox, Thunderbird | 2026-04-22 | 7.5 High |
| Use-after-free in the DOM: Core & HTML component. This vulnerability was fixed in Firefox 150, Firefox ESR 115.35, Firefox ESR 140.10, Thunderbird 150, and Thunderbird 140.10. | ||||
| CVE-2026-6754 | 1 Mozilla | 2 Firefox, Thunderbird | 2026-04-22 | 7.5 High |
| Use-after-free in the JavaScript Engine component. This vulnerability was fixed in Firefox 150, Firefox ESR 115.35, Firefox ESR 140.10, Thunderbird 150, and Thunderbird 140.10. | ||||
| CVE-2026-6758 | 1 Mozilla | 2 Firefox, Thunderbird | 2026-04-22 | 7.5 High |
| Use-after-free in the JavaScript: WebAssembly component. This vulnerability was fixed in Firefox 150 and Thunderbird 150. | ||||
| CVE-2026-26399 | 2026-04-22 | 5.3 Medium | ||
| A stack-use-after-return issue exists in the Arduino_Core_STM32 library prior to version 1.7.0. The pwm_start() function allocates a TIM_HandleTypeDef structure on the stack and passes its address to HAL initialization routines, where it is stored in a global timer handle registry. After the function returns, interrupt service routines may dereference this dangling pointer, resulting in memory corruption. | ||||
| CVE-2026-2436 | 3 Gnome, Libsoup, Redhat | 3 Libsoup, Libsoup, Enterprise Linux | 2026-04-21 | 6.5 Medium |
| A flaw was found in libsoup's SoupServer. A remote attacker could exploit a use-after-free vulnerability where the `soup_server_disconnect()` function frees connection objects prematurely, even if a TLS handshake is still pending. If the handshake completes after the connection object has been freed, a dangling pointer is accessed, leading to a server crash and a Denial of Service. | ||||
| CVE-2025-13020 | 1 Mozilla | 2 Firefox, Firefox Esr | 2026-04-20 | 8.8 High |
| Use-after-free in the WebRTC: Audio/Video component. This vulnerability was fixed in Firefox 145, Firefox ESR 140.5, Thunderbird 145, and Thunderbird 140.5. | ||||
| CVE-2025-13014 | 1 Mozilla | 2 Firefox, Firefox Esr | 2026-04-20 | 8.8 High |
| Use-after-free in the Audio/Video component. This vulnerability was fixed in Firefox 145, Firefox ESR 140.5, Firefox ESR 115.30, Thunderbird 145, and Thunderbird 140.5. | ||||
| CVE-2025-13027 | 1 Mozilla | 2 Firefox, Thunderbird | 2026-04-20 | 8.1 High |
| Memory safety bugs present in Firefox 144 and Thunderbird 144. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability was fixed in Firefox 145 and Thunderbird 145. | ||||
| CVE-2025-10911 | 1 Redhat | 3 Enterprise Linux, Hummingbird, Openshift | 2026-04-20 | 5.5 Medium |
| A use-after-free vulnerability was found in libxslt while parsing xsl nodes that may lead to the dereference of expired pointers and application crash. | ||||
| CVE-2025-49795 | 1 Redhat | 3 Enterprise Linux, Hummingbird, Jboss Core Services | 2026-04-20 | 7.5 High |
| A NULL pointer dereference vulnerability was found in libxml2 when processing XPath XML expressions. This flaw allows an attacker to craft a malicious XML input to libxml2, leading to a denial of service. | ||||
| CVE-2025-49794 | 1 Redhat | 15 Cert Manager, Enterprise Linux, Hummingbird and 12 more | 2026-04-20 | 9.1 Critical |
| A use-after-free vulnerability was found in libxml2. This issue occurs when parsing XPath elements under certain circumstances when the XML schematron has the <sch:name path="..."/> schema elements. This flaw allows a malicious actor to craft a malicious XML document used as input for libxml, resulting in the program's crash using libxml or other possible undefined behaviors. | ||||
| CVE-2026-24678 | 1 Freerdp | 1 Freerdp | 2026-04-18 | 7.5 High |
| FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.22.0, A capture thread sends sample responses using a freed channel callback after a device channel close, leading to a use after free in ecam_channel_write. This vulnerability is fixed in 3.22.0. | ||||
| CVE-2026-24676 | 1 Freerdp | 1 Freerdp | 2026-04-18 | 7.5 High |
| FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.22.0, AUDIN format renegotiation frees the active format list while the capture thread continues using audin->format, leading to a use after free in audio_format_compatible. This vulnerability is fixed in 3.22.0. | ||||
| CVE-2026-24680 | 1 Freerdp | 1 Freerdp | 2026-04-18 | 7.5 High |
| FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.22.0, sdl_Pointer_New frees data on failure, then pointer_free calls sdl_Pointer_Free and frees it again, triggering ASan UAF. This vulnerability is fixed in 3.22.0. | ||||
| CVE-2026-27950 | 1 Freerdp | 1 Freerdp | 2026-04-18 | 7.5 High |
| FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, the fix for the heap-use-after-free described in CVE-2026-24680 is incomplete. While the vulnerable execution flow referenced in the advisory exists in the SDL2 implementation, the fix appears to have been applied only to the SDL3 code path. In the SDL2 implementation, the pointer is not nulled after free. This creates a situation where the advisory suggests the vulnerability is fully resolved, while builds or environments still using SDL2 may retain the vulnerable logic. A complete fix is available in version 3.23.0. | ||||
| CVE-2026-5280 | 4 Apple, Google, Linux and 1 more | 4 Macos, Chrome, Linux Kernel and 1 more | 2026-04-18 | 8.8 High |
| Use after free in WebCodecs in Google Chrome prior to 146.0.7680.178 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High) | ||||
| CVE-2026-24491 | 1 Freerdp | 1 Freerdp | 2026-04-18 | 7.5 High |
| FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.22.0, video_timer can send client notifications after the control channel is closed, dereferencing a freed callback and triggering a use after free. This vulnerability is fixed in 3.22.0. | ||||
| CVE-2026-24681 | 1 Freerdp | 1 Freerdp | 2026-04-18 | 7.5 High |
| FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.22.0, aAsynchronous bulk transfer completions can use a freed channel callback after URBDRC channel close, leading to a use after free in urb_write_completion. This vulnerability is fixed in 3.22.0. | ||||
