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-2026-31053 1 Rizin 1 Rizin 2026-04-15 6.2 Medium
A double free vulnerability exists in librz/bin/format/le/le.c in the function le_load_fixup_record(). When processing malformed or circular LE fixup chains, relocation entries may be freed multiple times during error handling. A specially crafted LE binary can trigger heap corruption and cause the application to crash, resulting in a denial-of-service condition. An attacker with a crafted binary could cause a denial of service when the tool is integrated on a service pipeline.
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-2026-34446 2 Linuxfoundation, Onnx 2 Onnx, Onnx 2026-04-15 4.7 Medium
Open Neural Network Exchange (ONNX) is an open standard for machine learning interoperability. Prior to version 1.21.0, there is an issue in onnx.load, the code checks for symlinks to prevent path traversal, but completely misses hardlinks because a hardlink looks exactly like a regular file on the filesystem. This issue has been patched in version 1.21.0.
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-2025-9449 1 Dassault 1 Edrawings 2026-04-15 7.8 High
A Use After Free vulnerability affecting the PAR file reading procedure in SOLIDWORKS eDrawings on Release SOLIDWORKS Desktop 2025 could allow an attacker to execute arbitrary code while opening a specially crafted PAR file.
CVE-2022-49737 1 X.org 1 X Server 2026-04-15 7.7 High
In X.Org X server 20.11 through 21.1.16, when a client application uses easystroke for mouse gestures, the main thread modifies various data structures used by the input thread without acquiring a lock, aka a race condition. In particular, AttachDevice in dix/devices.c does not acquire an input lock.
CVE-2024-36353 2026-04-15 6.5 Medium
Insufficient clearing of GPU global memory could allow a malicious process running on the same GPU to read left over memory values potentially leading to loss of confidentiality.
CVE-2011-10034 1 Irai 1 Automgen 2026-04-15 N/A
AUTOMGEN versions up to and including 8.0.0.7 (also referenced as 8.022) contain a vulnerability in that project file handling frees an object and subsequently dereferences the stale pointer when processing certain malformed fields. The dangling-pointer use enables an attacker to influence an indirect call through attacker-controlled memory, resulting in denial-of-service. In some conditions, remote code execution may be possible.
CVE-2025-23281 1 Nvidia 1 Gpu Display Driver 2026-04-15 7 High
NVIDIA GPU Display Driver for Windows contains a vulnerability where an attacker with local unprivileged access that can win a race condition might be able to trigger a use-after-free error. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, data tampering, denial of service, or information disclosure.
CVE-2024-3299 2026-04-15 7.8 High
Out-Of-Bounds Write, Use of Uninitialized Resource and Use-After-Free vulnerabilities exist in the file reading procedure in eDrawings from Release SOLIDWORKS 2023 through Release SOLIDWORKS 2024. These vulnerabilities could allow an attacker to execute arbitrary code while opening a specially crafted SLDDRW or SLDPRT file. NOTE: this vulnerability was SPLIT from CVE-2024-1847.
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.
