Title
ImageMagick 7.1.2-30 before 7.1.2-32 Use After Free in WBINFO Decoder
Summary
ImageMagick 7.1.2-30 before 7.1.2-32 contains a use after free vulnerability in the WBINFO decoder that occurs when a memory allocation fails during image decoding. Attackers can supply a crafted image that, when decoded under memory allocation failure conditions, causes freed memory to be reused, crashing the application.

Title
FreeRDP before 3.32.0 Double Free via NSCodec plane growth failure
Summary
FreeRDP before 3.32.0 contains a double-free vulnerability in nsc_context_initialize_encode() that leaves dangling plane pointers after a partial buffer growth failure. Attackers using a crafted RDP client can negotiate NSCodec with a large desktop geometry to trigger allocation failure, crashing the server during context teardown.

Xerial snappy-java 1.1.7.4 before 1.1.10.10 Double Release of Pooled Buffers in SnappyFramedInputStream
Summary
Xerial snappy-java from 1.1.7.4 before 1.1.10.10 contains a double release vulnerability in SnappyFramedInputStream that returns pooled buffers twice when replacement allocation fails. Attackers can supply framed data with a large declared chunk length to trigger OutOfMemoryError, causing shared backing arrays that expose or overwrite other streams' decompressed data.

Summary
OpenPrinting CUPS before 2.4.20 contains a double-free in printer-class management. When CUPS-Add-Modify-Class replaces an existing class member list, add_class() frees pclass->printers without clearing the pointer. If subsequent validation fails, the class retains the dangling pointer; CUPS-Delete-Class subsequently frees the same allocation in cupsdDeletePrinter(). A client authorized to modify and delete classes can cause scheduler-wide denial of service. The default policy requires @SYSTEM privileges.

ImageMagick: Use-After-Free in RSVG decoder that is build without cairo support
Summary
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-30 and 6.9.13-55, when ImageMagick is built without Cairo support, a crafted RSVG image that reaches a resource limit can cause the RSVG decoder to free image state twice and then use freed memory, crashing the process. This issue is fixed in versions 7.1.2-30 and 6.9.13-55.

Title
Double free in OmniOS and SmartOS ipmgmtd allows local users to crash the daemon
Summary
A double free in the IP management daemon (ipmgmtd) of OmniOS and SmartOS allows a local user to crash the daemon. When authorizing a door request that modifies interface configuration, ipmgmt_handler() in usr/src/cmd/cmd-inet/lib/ipmgmtd/ipmgmt_door.c frees the caller's credential with ucred_free() immediately after reading the user ID, and frees it a second time on the error path if the authorization check fails. An unprivileged local user who does not hold the solaris.network.interface.config authorization can send such a request, for example IPMGMT_CMD_RESETIF, to the ipmgmtd door, causing ipmgmtd to abort; repeated requests place the svc:/network/ip-interface-management service into maintenance, preventing IP interface configuration. The early free was introduced in 2014 to support lx-branded zones (OmniOS commit 4c170900) and is not present in upstream illumos-gate. It affects OmniOS r151020 and later, and SmartOS, prior to the fix.

Title
Code Execution in Host Sentry Process via Double Free in gVisor VFS MemoryFile
Summary
Use-after-free vulnerability in VFS in Google gVisor prior to release 20260831.0 on all platforms allows a local attacker with standard container privileges to achieve code execution in the host sentry process by double-freeing the backing MemoryFile from an in-sandbox overlay filesystem. The sentry process remains confined by host-level Linux seccomp and namespace boundaries.

Double Free in GitLab
Summary
GitLab has remediated an issue in GitLab CE/EE affecting all versions from 19.2 before 19.2.7, 19.3 before 19.3.3, and 19.4 before 19.4.1 that under certain conditions could have allowed an authenticated user to execute arbitrary code on the GitLab server due to a double free issue when parsing a specially crafted regular expression in a CI/CD configuration.

Mitigation
Architecture and Design
Choose a language that provides automatic memory management.
Mitigation
Implementation
Ensure that each allocation is freed only once. After freeing a chunk, set the pointer to NULL to ensure the pointer cannot be freed again. In complicated error conditions, be sure that clean-up routines respect the state of allocation properly. If the language is object oriented, ensure that object destructors delete each chunk of memory only once.
Mitigation
Implementation
Use a static analysis tool to find double free instances.
