Concurrent removals of certain anonymous shared memory mappings by using the UMTX_SHM_DESTROY sub-request of UMTX_OP_SHM can lead to decreasing the reference count of the object representing the mapping too many times, causing it to be freed too early.

A malicious code exercizing the UMTX_SHM_DESTROY sub-request in parallel can panic the kernel or enable further Use-After-Free attacks, potentially including code execution or Capsicum sandbox escape.

The ctl_report_supported_opcodes function did not sufficiently validate a field provided by userspace, allowing an arbitrary write to a limited amount of kernel help memory.

Malicious software running in a guest VM that exposes virtio_scsi can exploit the vulnerabilities to achieve code execution on the host in the bhyve userspace process, which typically runs as root. Note that bhyve runs in a Capsicum sandbox, so malicious code is constrained by the capabilities available to the bhyve process. A malicious iSCSI initiator could achieve remote code execution on the iSCSI target host.

An insufficient boundary validation in the USB code could lead to an out-of-bounds write on the heap, with data controlled by the caller.

A malicious, privileged software running in a guest VM can exploit the vulnerability to achieve code execution on the host in the bhyve userspace process, which typically runs as root. Note that bhyve runs in a Capsicum sandbox, so malicious code is constrained by the capabilities available to the bhyve process.

The Chatbot with ChatGPT WordPress plugin before 2.4.5 does not validate access on some REST routes, allowing for an unauthenticated user to purge error and chat logs

The Ivory Search – WordPress Search Plugin plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 5.5.6 via the ajax_load_posts function. This makes it possible for unauthenticated attackers to extract text data from password-protected posts using the boolean-based attack on the AJAX search form

The Bit File Manager plugin for WordPress is vulnerable to Remote Code Execution in versions 6.0 to 6.5.5 via the 'checkSyntax' function. This is due to writing a temporary file to a publicly accessible directory before performing file validation. This makes it possible for unauthenticated attackers to execute code on the server if an administrator has allowed Guest User read permissions.

Malicious software running in a guest VM can exploit the buffer overflow to achieve code execution on the host in the bhyve userspace process, which typically runs as root. Note that bhyve runs in a Capsicum sandbox, so malicious code is constrained by the capabilities available to the bhyve process.

A missing null-termination character in the last element of an nvlist array string can lead to writing outside the allocated buffer.

A malicious value of size in a structure of packed libnv can cause an integer overflow, leading to the allocation of a smaller buffer than required for the parsed data.

Webmin before 2.202 and Virtualmin before 7.20.2 allow a network traffic loop via spoofed UDP packets on port 10000.
