| CVE-2026-23234 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: f2fs: fix to avoid UAF in f2fs_write_end_io() As syzbot reported an use-after-free issue in f2fs_write_end_io(). It is caused by below race condition: loop device umount - worker_thread - loop_process_work - do_req_filebacked - lo_rw_aio - lo_rw_aio_complete - blk_mq_end_request - blk_update_request - f2fs_write_end_io - dec_page_count - folio_end_writeback - kill_f2fs_super - kill_block_super - f2fs_put_super : free(sbi) : get_pages(, F2FS_WB_CP_DATA) accessed sbi which is freed In kill_f2fs_super(), we will drop all page caches of f2fs inodes before call free(sbi), it guarantee that all folios should end its writeback, so it should be safe to access sbi before last folio_end_writeback(). Let's relocate ckpt thread wakeup flow before folio_end_writeback() to resolve this issue. | ||||
| CVE-2026-3847 | 1 Mozilla | 1 Firefox | 2026-04-15 | 8.8 High |
| Memory safety bugs present in Firefox 148.0.2. 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 148.0.2. | ||||
| CVE-2026-27854 | 1 Powerdns | 1 Dnsdist | 2026-04-15 | 4.8 Medium |
| An attacker might be able to trigger a use-after-free by sending crafted DNS queries to a DNSdist using the DNSQuestion:getEDNSOptions method in custom Lua code. In some cases DNSQuestion:getEDNSOptions might refer to a version of the DNS packet that has been modified, thus triggering a use-after-free and potentially a crash resulting in denial of service. | ||||
| CVE-2026-3777 | 4 Apple, Foxit, Foxitsoftware and 1 more | 6 Macos, Pdf Editor, Pdf Reader and 3 more | 2026-04-15 | 5.5 Medium |
| The application does not properly validate the lifetime and validity of internal view cache pointers after JavaScript changes the document zoom and page state. When a script modifies the zoom property and then triggers a page change, the original view object may be destroyed while stale pointers are still kept and later dereferenced, which under crafted JavaScript and document structures can lead to a use-after-free condition and potentially allow arbitrary code execution. | ||||
| CVE-2026-5877 | 4 Apple, Google, Linux and 1 more | 4 Macos, Chrome, Linux Kernel and 1 more | 2026-04-15 | 8.8 High |
| Use after free in Navigation in Google Chrome prior to 147.0.7727.55 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: Medium) | ||||
| CVE-2026-34734 | 1 Hdfgroup | 1 Hdf5 | 2026-04-15 | 7.8 High |
| HDF5 is software for managing data. In 1.14.1-2 and earlier, a heap-use-after-free was found in the h5dump helper utility. An attacker who can supply a malicious h5 file can trigger a heap use-after-free. The freed object is referenced in a memmove call from H5T__conv_struct. The original object was allocated by H5D__typeinfo_init_phase3 and freed by H5D__typeinfo_term. | ||||
| CVE-2026-34983 | 1 Bytecodealliance | 1 Wasmtime | 2026-04-15 | 5.0 Medium |
| Wasmtime is a runtime for WebAssembly. In 43.0.0, cloning a wasmtime::Linker is unsound and can result in use-after-free bugs. This bug is not controllable by guest Wasm programs. It can only be triggered by a specific sequence of embedder API calls made by the host. Specifically, the following steps must occur to trigger the bug clone a wasmtime::Linker, drop the original linker instance, use the new, cloned linker instance, resulting in a use-after-free. This vulnerability is fixed in 43.0.1. | ||||
| CVE-2025-33217 | 1 Nvidia | 6 Display Driver, Geforce, Quadro and 3 more | 2026-04-15 | 7.8 High |
| NVIDIA Display Driver for Windows contains a vulnerability where an attacker could trigger a use after free. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, data tampering, denial of service, and information disclosure. | ||||
| CVE-2025-33220 | 1 Nvidia | 6 Geforce, Quadro, Rtx and 3 more | 2026-04-15 | 7.8 High |
| NVIDIA vGPU software contains a vulnerability in the Virtual GPU Manager, where a malicious guest could cause heap memory access after the memory is freed. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, data tampering, denial of service, or information disclosure. | ||||
| CVE-2025-55118 | 1 Bmc | 1 Control-m/agent | 2026-04-15 | 8.9 High |
| Memory corruptions can be remotely triggered in the Control-M/Agent when SSL/TLS communication is configured. The issue occurs in the following cases: * Control-M/Agent 9.0.20: SSL/TLS configuration is set to the non-default setting "use_openssl=n"; * Control-M/Agent 9.0.21 and 9.0.22: Agent router configuration uses the non-default settings "JAVA_AR=N" and "use_openssl=n" | ||||
| CVE-2024-4741 | 2 Openssl, Redhat | 2 Openssl, Enterprise Linux | 2026-04-15 | 7.5 High |
| Issue summary: Calling the OpenSSL API function SSL_free_buffers may cause memory to be accessed that was previously freed in some situations Impact summary: A use after free can have a range of potential consequences such as the corruption of valid data, crashes or execution of arbitrary code. However, only applications that directly call the SSL_free_buffers function are affected by this issue. Applications that do not call this function are not vulnerable. Our investigations indicate that this function is rarely used by applications. The SSL_free_buffers function is used to free the internal OpenSSL buffer used when processing an incoming record from the network. The call is only expected to succeed if the buffer is not currently in use. However, two scenarios have been identified where the buffer is freed even when still in use. The first scenario occurs where a record header has been received from the network and processed by OpenSSL, but the full record body has not yet arrived. In this case calling SSL_free_buffers will succeed even though a record has only been partially processed and the buffer is still in use. The second scenario occurs where a full record containing application data has been received and processed by OpenSSL but the application has only read part of this data. Again a call to SSL_free_buffers will succeed even though the buffer is still in use. While these scenarios could occur accidentally during normal operation a malicious attacker could attempt to engineer a stituation where this occurs. We are not aware of this issue being actively exploited. The FIPS modules in 3.3, 3.2, 3.1 and 3.0 are not affected by this issue. | ||||
| CVE-2024-4418 | 1 Redhat | 3 Advanced Virtualization, Enterprise Linux, Rhel Eus | 2026-04-15 | 6.2 Medium |
| A race condition leading to a stack use-after-free flaw was found in libvirt. Due to a bad assumption in the virNetClientIOEventLoop() method, the `data` pointer to a stack-allocated virNetClientIOEventData structure ended up being used in the virNetClientIOEventFD callback while the data pointer's stack frame was concurrently being "freed" when returning from virNetClientIOEventLoop(). The 'virtproxyd' daemon can be used to trigger requests. If libvirt is configured with fine-grained access control, this issue, in theory, allows a user to escape their otherwise limited access. This flaw allows a local, unprivileged user to access virtproxyd without authenticating. Remote users would need to authenticate before they could access it. | ||||
| CVE-2024-38920 | 1 Open Robotics | 2 Nav2 Humble, Ros2 | 2026-04-15 | 9.1 Critical |
| Open Robotics Robotic Operating System 2 (ROS2) and Nav2 humble versions were discovered to contain a use-after-free via the nav2_amcl process. This vulnerability is triggerd via remotely sending a request for change the value of dynamic-parameter`/amcl max_beams` . | ||||

| Open Robotics Robotic Operating System 2 (ROS2) and Nav2 humble version was discovered to contain a use-after-free in the nav2_amcl process. This vulnerability is triggered via sending a request to change dynamic parameters. | ||||
| CVE-2025-11677 | 1 Warmcat | 1 Libwebsockets | 2026-04-15 | 3.7 Low |
| Use After Free in WebSocket server implementation in lws_handshake_server in warmcat libwebsockets may allow an attacker, in specific configurations where the user provides a callback function that handles LWS_CALLBACK_HTTP_CONFIRM_UPGRADE, to achieve denial of service. | ||||
