Title
NexTOR_IP_CHANGER has PATH Injection Leading to Arbitrary Command Execution
Summary
NexTor IP Changer is a command-line tool that leverages the Tor network to periodically rotate a user's IP address. Versions prior to 2.0.0 have a command execution vulnerability due to unsafe use of `shell=True` with commands that rely on executable resolution through the `PATH` environment variable. An attacker controlling the execution environment can place malicious executables such as sudo earlier in the `PATH`, resulting in execution of attacker-controlled code. Version 2.0.0 fixes the issue.

Title
pam_usb: Thread-unsafe static pointer in log.c causes data race under concurrent PAM authentication
Summary
pam_usb provides hardware authentication for Linux using ordinary removable media. Prior to 0.9.1, src/log.c contains a process-wide static pointer that is written on every PAM invocation with the address of a stack-local variable. This violates the PAM re-entrancy requirement and creates a data race when the PAM stack is invoked concurrently from multiple threads. This vulnerability is fixed in 0.9.1.

Title
Incus has a Nil-Pointer Dereference Panic via Instance Backup Import (volume omitted)
Summary
Incus is a system container and virtual machine manager. Prior to version 7.1.0, `(*backend).CreateInstanceFromBackup` in `internal/server/storage/backend.go` contains a nil-pointer dereference that an authenticated user with permission to create instances in any project can trigger remotely by uploading a crafted backup tarball. The Incus daemon panics and the process crashes, causing denial of service to every project on that cluster member. This is a sibling of `GHSA-fwj8-62r8-8p8m`, `GHSA-r7w7-mmxr-47r9`, and `GHSA-x5r6-jr56-89pv` (all assigned 2026-05-04). Those patches added guards on adjacent fields of the same `backup/config.Config` struct; the `Volume` field on the instance-import path was missed. Version 7.1.0 contains an updated patch.

CVE-2026-47709 (GCVE-0-2026-47709)

Title
libheif has a NULL pointer dereference in heif_image_handle_get_image_tiling for malformed unci image missing ispe
Summary
libheif is a HEIF and AVIF file format decoder and encoder. Versions prior to 1.22.0 crashes in the public C API `heif_image_handle_get_image_tiling()` when a malformed uncompressed HEIF image item has an associated `uncC` property but no associated `ispe` property. In debug builds this trips the `ispe && uncC` assertion in `ImageItem_uncompressed::get_heif_image_tiling()`. In a release/NDEBUG ASan build, the same file causes a null pointer read at address `0xa8`. Version 1.22.0 fixes the issue.

Mitigation MIT-56
Implementation
For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].
Mitigation
Requirements
Select a programming language that is not susceptible to these issues.
Mitigation
Implementation
Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
Mitigation
Architecture and Design
Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.
Mitigation
Implementation
Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
