Common Weakness Enumeration

CWE-416

Weakness Allowed

Use After Free

Abstraction: Variant · Status: Stable

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Mapping guidance

This CWE entry is at the Variant level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.

Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.

Fuzzing

Fuzz testing (fuzzing) is a powerful technique for generating large numbers of diverse inputs - either randomly or algorithmically - and dynamically invoking the code with those inputs. Even with random inputs, it is often capable of generating unexpected results such as crashes, memory corruption, or resource consumption. Fuzzing effectively produces repeatable test cases that clearly indicate bugs, which helps developers to diagnose the issues.

Effectiveness: High

Automated Static Analysis

Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)

Effectiveness: High

Automated Dynamic Analysis

Use tools that are integrated during compilation to insert runtime error-checking mechanisms related to memory safety errors, such as AddressSanitizer (ASan) for C/C++ [REF-1518].

Effectiveness: Moderate

Crafted inputs are necessary to reach the code containing the error, such as generated by fuzzers. Also, these tools may reduce performance, and they only report the error condition - not the original mistake that led to the error.

CVE-2026-125704 (GCVE-0-2026-125704)

Vulnerability from cvelistv5 – Published: 2026-11-10 10:43 – Updated: 2026-11-10 11:45
VLAI
Title
Gstreamer: gstreamer: use-after-free in gstreamer core buffer value deserialization
Summary
A use-after-free flaw was found in GStreamer core buffer value deserialization. When crafted serialized buffer data contains an invalid character, an error path frees a mapped buffer before unmapping it. An application that parses untrusted caps or structure data could crash; a network-facing GStreamer Data Protocol receiver can process such data without user interaction. Further impact has not been established.

Title
Ettercap through 0.8.4.1 Use-After-Free via PCRE2 Filter Substitution
Summary
Ettercap through 0.8.4.1 contains a use-after-free vulnerability in func_pcre() in src/ec_filter.c that reads the PCRE2 ovector after freeing match data. Network-adjacent attackers can send packets matching a loaded pcre_regex() substitution filter to corrupt memory and potentially execute code as root.

Title
FreeRDP before 3.33.0 Use-After-Free via Stale Brush Cache Pointer
Summary
FreeRDP before 3.33.0 contains a heap use-after-free vulnerability in update_gdi_patblt(), update_gdi_polygon_cb() and update_gdi_mem3blt() that retain stale brush cache pointers. A malicious RDP server can resend CACHE_BRUSH to the same slot then send PATBLT, causing clients to read freed heap memory, disclosing data or crashing.

Title
FFmpeg through 9.0.2 Use-After-Free via NVDEC Stale Bitstream Pointer
Summary
FFmpeg through 9.0.2 contains a use-after-free vulnerability in libavcodec/nvdec.c because ff_nvdec_start_frame() fails to reset ctx->bitstream after slice errors. Attackers can supply crafted video that abandons a picture before end_frame, causing cuvidDecodePicture() to read freed heap memory, crashing applications or exposing stale heap contents.

Title
FFmpeg through 9.0.2 Use-After-Free in MJPEG Hardware-Accelerated Decoding
Summary
FFmpeg through 9.0.2 contains a use after free vulnerability in libavcodec/mjpegdec.c that allows attackers to trigger freed buffer reads by sending a SOF marker without a preceding SOI. Attackers can supply crafted MJPEG streams causing ff_mjpeg_decode_sof() to pass a stale raw_image_buffer pointer to hwaccel decoders like NVDEC, crashing applications or leaking heap contents.

Title
Fraunhofer HHI VVdeC before 3.2.1 Use-After-Free via DecLibRecon::createSubPicRefBufs
Summary
Fraunhofer HHI VVdeC before 3.2.1 contains a heap use-after-free vulnerability in DecLibRecon::createSubPicRefBufs because decompressPicture clears m_subPicExtTasks without waiting for pending tasks. Attackers can supply a crafted multi-subpicture VVC bitstream to decoders using two or more threads, causing heap memory corruption or a decoder crash.

CVE-2026-124307 (GCVE-0-2026-124307)

Title
Fraunhofer HHI VVdeC before 3.2.1 Heap Use-After-Free via ALF APS Redefinition
Summary
Fraunhofer HHI VVdeC before 3.2.1 contains a heap use-after-free vulnerability that allows attackers to corrupt memory by redefining an ALF adaptation parameter set id still referenced by slices. Attackers can supply a crafted VVC bitstream that, with multithreaded decoding, makes worker threads dereference freed APS objects in CABACReader::readAlf() and AdaptiveLoopFilter::reconstructCoeff(), causing crashes or heap corruption.

Title
CivetWeb through 1.16 HTTP/2 Use-After-Free via Stale Pseudo-Header State
Summary
CivetWeb through 1.16, when built with USE_HTTP2 and enable_http2 on, contains a use-after-free vulnerability in handle_http2() that retains freed :method and :path pointers. Unauthenticated remote attackers can send a later HEADERS frame omitting these pseudo-headers to influence request method or path seen by access rules, or crash the server.

Title
FreeRDP before 3.32.2 Use-After-Free in Smartcard Emulation ReleaseContext
Summary
FreeRDP before 3.32.2 contains a use-after-free vulnerability in Emulate_SCardReleaseContext that frees the emulated SCardContext before its worker thread is cancelled and joined. A malicious server can send ESTABLISHCONTEXT, a long-timeout GETSTATUSCHANGE, then RELEASECONTEXT smartcard IRPs to corrupt heap memory or crash clients using smartcard emulation.

Strategy: Attack Surface Reduction

When freeing pointers, be sure to set them to NULL once they are freed. However, the utilization of multiple or complex data structures may lower the usefulness of this strategy.
