Common Weakness Enumeration

CWE-416

Allowed

Use After Free

Abstraction: Variant · Status: Stable

API response cwe.mitre.org

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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

12226 vulnerabilities reference this CWE, most recent first.

Title
netty-tcnative 2.0.66.Final before 2.0.84.Final Use-After-Free in Session Ticket Callback
Summary
netty-tcnative 2.0.66.Final before 2.0.84.Final built against OpenSSL 3.x contains a use-after-free vulnerability in ssl_tlsext_ticket_key_cb during session ticket key rotation. Remote clients performing TLS handshakes while setSessionTicketKeys0 frees the shared key array cause OpenSSL to read freed HMAC keys, crashing or corrupting ticket processing.

CVE-2026-115379 (GCVE-0-2026-115379)

Title
Wasmtime 47.0.0 before 48.0.4 and 49.0.0 before 49.0.2 GC Heap Corruption via try_call
Summary
Wasmtime 47.0.0 before 48.0.4 and 49.0.0 before 49.0.2 contains a missing GC rooting vulnerability that leaves references live across try_call unrooted when compiling Wasm modules. Attackers can supply Wasm modules whose callee triggers garbage collection, leaving stale or dangling references that cause GC heap corruption or incorrect execution.

Title
Sharp before 0.35.5 RCE via librsvg Dependency Memory Vulnerability
Summary
sharp before 0.35.5 bundles a librsvg dependency affected by a memory-related vulnerability (CVE-2026-96889) that, under certain runtime-specific conditions, can lead to code execution on glibc-based Linux. An attacker can supply a crafted SVG image that, when decoded by sharp through librsvg, may result in arbitrary code execution.

Title
FreeRDP 3.32.0 Use-After-Free via drdynvc Virtual Channel PDU
Summary
FreeRDP 3.32.0 contains a use-after-free vulnerability in the drdynvc channel that frees a pool-owned stream with the owned-stream deallocator when totalLength is smaller than the chunk size. A malicious RDP server can send a single well-formed Virtual Channel PDU to trigger the free and crash the client during teardown.

CVE-2026-112402 (GCVE-0-2026-112402)

Title
Pillow: Double free in ImagingScaleAffine on calloc failure via Image.transform
Summary
Pillow is a Python imaging library. Prior to 13.0.0, Pillow can double free image memory when ImagingScaleAffine encounters a selective allocation failure. The affected fast path handles Transform.EXTENT or pure scale-and-translate Transform.AFFINE operations with the default NEAREST resampling. The output image allocation must succeed while the additional per-column lookup allocation fails, after which the error path deletes image storage that later cleanup releases again. An attacker who can drive such a large Image.transform() operation under memory pressure may trigger the failure. This can crash the process and may corrupt memory. This issue is fixed in version 13.0.0.
Severity
8.7 (High)

CVE-2026-112396 (GCVE-0-2026-112396)

Vulnerability from cvelistv5 – Published: 2026-10-19 21:02 – Updated: 2026-10-20 16:09

Title
Pillow: Heap use-after-free when encoding TIFF to an in-memory buffer
Summary
Pillow is a Python imaging library. From 11.3.0 until 13.0.0, Pillow has a heap use-after-free when libtiff rejects a tag while encoding TIFF data to an in-memory buffer. When an application saves attacker-influenced TIFF tags to BytesIO, libtiff can reject a tag during encoding in ImagingLibTiffEncode; the error path then frees the output buffer without closing or clearing the TIFF handle, and later cleanup flushes through the write callback into freed memory, which can crash the process and may enable code execution. This issue is fixed in version 13.0.0.
Severity
5.9 (Medium)

Gimp: gimp: use-after-free in xcf loader via prop_selected_path
Summary
A flaw was found in GIMP. Opening a crafted XCF that selects a path and then fails to load that path can cause a use-after-free in the main process, leading to a crash and potentially arbitrary code execution.

CVE-2026-112258 (GCVE-0-2026-112258)

Vulnerability from cvelistv5 – Published: 2026-10-19 21:37 – Updated: 2026-10-21 20:45

Title
Gimp: gimp: use-after-free in xcf loader via prop_linked and prop_selection on channels
Summary
A flaw was found in GIMP. The XCF loader can leave a dangling pointer in the linked-channels list when a linked channel is later destroyed via a selection property. Opening a crafted XCF file can cause a use-after-free in the main GIMP process, leading to a crash and potentially arbitrary code execution.

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.
