CVE-2026-23868 1 Giflib 1 Giflib 2026-04-17 5.1 Medium
Giflib contains a double-free vulnerability that is the result of a shallow copy in GifMakeSavedImage and incorrect error handling. The conditions needed to trigger this vulnerability are difficult but may be possible.
CVE-2026-32873 1 Vshakitskiy 1 Ewe 2026-04-17 7.5 High
ewe is a Gleam web server. Versions 0.8.0 through 3.0.4 contain a bug in the handle_trailers function where rejected trailer headers (forbidden or undeclared) cause an infinite loop. When handle_trailers encounters such a trailer, three code paths (lines 520, 523, 526) recurse with the original buffer (rest) instead of advancing past the rejected header (Buffer(header_rest, 0)), causing decoder.decode_packet to re-parse the same header on every iteration. The resulting loop has no timeout or escape — the BEAM process permanently wedges at 100% CPU. Any application that calls ewe.read_body on chunked requests is affected, and this is exploitable by any unauthenticated remote client before control returns to application code, making an application-level workaround impossible. This issue is fixed in version 3.0.5.
CVE-2026-39316 1 Openprinting 1 Cups 2026-04-16 4 Medium
OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In versions 2.4.16 and prior, a use-after-free vulnerability exists in the CUPS scheduler (cupsd) when temporary printers are automatically deleted. cupsdDeleteTemporaryPrinters() in scheduler/printers.c calls cupsdDeletePrinter() without first expiring subscriptions that reference the printer, leaving cupsd_subscription_t.dest as a dangling pointer to freed heap memory. The dangling pointer is subsequently dereferenced at multiple code sites, causing a crash (denial of service) of the cupsd daemon. With heap grooming, this can be leveraged for code execution.
CVE-2026-5883 4 Apple, Google, Linux and 1 more 4 Macos, Chrome, Linux Kernel and 1 more 2026-04-16 8.8 High

CVE-2026-26983 1 Imagemagick 1 Imagemagick 2026-04-16 5.3 Medium
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, the MSL interpreter crashes when processing a invalid `<map>` element that causes it to use an image after it has been freed. Versions 7.1.2-15 and 6.9.13-40 contain a patch.
CVE-2026-28799 1 Pjsip 2 Pjproject, Pjsip 2026-04-16 7.5 High
PJSIP is a free and open source multimedia communication library written in C. Prior to version 2.17, a heap use-after-free vulnerability exists in PJSIP's event subscription framework (evsub.c) that is triggered during presence unsubscription (SUBSCRIBE with Expires=0). This issue has been patched in version 2.17.
CVE-2026-28687 1 Imagemagick 1 Imagemagick 2026-04-16 5.3 Medium
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, a heap use-after-free vulnerability in ImageMagick's MSL decoder allows an attacker to trigger access to freed memory by crafting an MSL file. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41.
CVE-2026-30978 2 Color, Internationalcolorconsortium 2 Iccdev, Iccdev 2026-04-16 7.8 High
iccDEV provides a set of libraries and tools for working with ICC color management profiles. Prior to 2.3.1.5, there is a heap-use-after-free in CIccCmm::AddXform() causing invalid vptr dereference and crash. This vulnerability is fixed in 2.3.1.5.
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-2026-34988 1 Bytecodealliance 1 Wasmtime 2026-04-15 6.3 Medium
Wasmtime is a runtime for WebAssembly. From 28.0.0 to before 36.0.7, 42.0.2, and 43.0.1, Wasmtime's implementation of its pooling allocator contains a bug where in certain configurations the contents of linear memory can be leaked from one instance to the next. The implementation of resetting the virtual memory permissions for linear memory used the wrong predicate to determine if resetting was necessary, where the compilation process used a different predicate. This divergence meant that the pooling allocator incorrectly deduced at runtime that resetting virtual memory permissions was not necessary while compile-time determine that virtual memory could be relied upon. The pooling allocator must be in use, Config::memory_guard_size configuration option must be 0, Config::memory_reservation configuration must be less than 4GiB, and pooling allocator must be configured with max_memory_size the same as the memory_reservation value in order to exploit this vulnerability. If all of these conditions are applicable then when a linear memory is reused the VM permissions of the previous iteration are not reset. This means that the compiled code, which is assuming out-of-bounds loads will segfault, will not actually segfault and can read the previous contents of linear memory if it was previously mapped. This represents a data leakage vulnerability between guest WebAssembly instances which breaks WebAssembly's semantics and additionally breaks the sandbox that Wasmtime provides. Wasmtime is not vulnerable to this issue with its default settings, nor with the default settings of the pooling allocator, but embeddings are still allowed to configure these values to cause this vulnerability. This vulnerability is fixed in 36.0.7, 42.0.2, and 43.0.1.
CVE-2025-61664 1 Redhat 2 Enterprise Linux, Openshift 2026-04-15 4.9 Medium
A vulnerability in the GRUB2 bootloader has been identified in the normal module. This flaw, a memory Use After Free issue, occurs because the normal_exit command is not properly unregistered when its related module is unloaded. An attacker can exploit this condition by invoking the command after the module has been removed, causing the system to improperly access a previously freed memory location. This leads to a system crash or possible impacts in data confidentiality and integrity.
CVE-2025-54770 1 Redhat 2 Enterprise Linux, Openshift 2026-04-15 4.9 Medium
A vulnerability has been identified in the GRUB2 bootloader's network module that poses an immediate Denial of Service (DoS) risk. This flaw is a Use-after-Free issue, caused because the net_set_vlan command is not properly unregistered when the network module is unloaded from memory. An attacker who can execute this command can force the system to access memory locations that are no longer valid. Successful exploitation leads directly to system instability, which can result in a complete crash and halt system availability
CVE-2025-54771 1 Redhat 2 Enterprise Linux, Openshift 2026-04-15 4.9 Medium
A use-after-free vulnerability has been identified in the GNU GRUB (Grand Unified Bootloader). The flaw occurs because the file-closing process incorrectly retains a memory pointer, leaving an invalid reference to a file system structure. An attacker could exploit this vulnerability to cause grub to crash, leading to a Denial of Service. Possible data integrity or confidentiality compromise is not discarded.
