CVSS v3.1 |
| A ThreadX module allocates the control blocks of its kernel objects from the Module Manager's object pool, and can ask for that memory back by address with `txm_module_object_deallocate`. The manager released it whatever was in it, including a control block the kernel was still using. Deallocation is not deletion: the object stays on the created list for its type, a thread stays wherever it was on the ready or suspension lists and stays schedulable, and an active timer stays on the timer list. The byte pool is meanwhile free to hand those same bytes to the next allocation. |
| When an FTP wildcard `LIST` operation fails, libcurl omits the restoration
path meant for successful listings, leaving the write callback set to the
internal listing parser and the write callback data pointing directly to the
easy handle. Subsequent reuse of this handle triggers an immediate crash, and
cloning it via `curl_easy_duphandle()` copies this corrupted state into the
duplicate. If the original handle is subsequently freed, executing a transfer
on the cloned handle causes a heap use-after-free read against the dangling
handle reference; alternatively, reusing the original or cloned handle while
changing only `CURLOPT_WRITEDATA` (and omitting `CURLOPT_WRITEFUNCTION`)
results in type confusion, forcing the internal parser to interpret incoming
server response bytes into memory at the application-supplied write data
pointer. |
| During an upload, curl mishandles HTTP/2 `RST_STREAM` received from the server
(with reason `HTTP_1_1_REQUIRED` or `REFUSED_STREAM`) leading to a use after
free of a `struct Curl_easy` object. |
| Use after free in Microsoft Windows Media Foundation allows an authorized attacker to elevate privileges locally. |
| A use after free issue was addressed with improved memory management. This issue is fixed in iOS 26.7 and iPadOS 26.7, iOS 27 and iPadOS 27, macOS Golden Gate 27, macOS Sequoia 15.8, macOS Tahoe 26.7, tvOS 27, visionOS 27, watchOS 27. Processing a maliciously crafted media file may lead to unexpected app termination or corrupt process memory. |
| Use after free in Windows Win32 Kernel Subsystem allows an authorized attacker to elevate privileges locally. |
| Use after free in Windows Virtualization-Based Security (VBS) Enclave allows an authorized attacker to elevate privileges locally. |
| Use after free in Windows Installer allows an authorized attacker to elevate privileges locally. |
| Use after free in Windows Broadcast DVR User Service allows an authorized attacker to elevate privileges locally. |
| Use after free in Windows Broadcast DVR User Service allows an authorized attacker to elevate privileges locally. |
| 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. |
