Deno is a JavaScript, TypeScript, and WebAssembly runtime. In version 1.39.0, use of raw file descriptors in `op_node_ipc_pipe()` leads to premature close of arbitrary file descriptors, allowing standard input to be re-opened as a different resource resulting in permission prompt bypass. Node child_process IPC relies on the JS side to pass the raw IPC file descriptor to `op_node_ipc_pipe()`, which returns a `IpcJsonStreamResource` ID associated with the file descriptor. On closing the resource, the raw file descriptor is closed together. Use of raw file descriptors in `op_node_ipc_pipe()` leads to premature close of arbitrary file descriptors. This allow standard input (fd 0) to be closed and re-opened for a different resource, which allows a silent permission prompt bypass. This is exploitable by an attacker controlling the code executed inside a Deno runtime to obtain arbitrary code execution on the host machine regardless of permissions. This bug is known to be exploitable. There is a working exploit that achieves arbitrary code execution by bypassing prompts from zero permissions, additionally abusing the fact that Cache API lacks filesystem permission checks. The attack can be conducted silently as stderr can also be closed, suppressing all prompt outputs. Version 1.39.1 fixes the bug.

ESXi, Workstation, Fusion, VMRC and Horizon Client contain a use-after-free vulnerability in the virtual sound device. VMware has evaluated the severity of this issue to be in the Important severity range with a maximum CVSSv3 base score of 8.5.

A race condition exists in a driver potentially leading to a use-after-free condition.

A use-after-free issue was addressed with improved memory management. This issue is fixed in iOS 18.1 and iPadOS 18.1, watchOS 11.1, visionOS 2.1, tvOS 18.1. An app may be able to cause unexpected system termination or corrupt kernel memory.

A use-after-free flaw was found in cgroup1_parse_param in kernel/cgroup/cgroup-v1.c in the Linux kernel's cgroup v1 parser. A local attacker with a user privilege could cause a privilege escalation by exploiting the fsconfig syscall parameter leading to a container breakout and a denial of service on the system.

The function ctl_write_buffer incorrectly set a flag which resulted in a kernel Use-After-Free when a command finished processing. 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.

win32k.sys in the kernel-mode drivers in Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows Server 2012, and Windows RT does not properly handle objects in memory, which allows local users to gain privileges via a crafted application, aka "Win32k Dereference Vulnerability."

In TBD of TBD, there is a possible use after free due to a race condition. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

In TBD of TBD, there is a possible use-after-free due to a logic error in the code. This could lead to local escalation of privilege in the kernel with no additional execution privileges needed. User interaction is not needed for exploitation.

in OpenHarmony v4.1.0 and prior versions allow a local attacker cause the common permission is upgraded to root and sensitive information leak through use after free.

Improper handling of multiple session supported by PVM backend can lead to use after free in Snapdragon Auto, Snapdragon Mobile

Memory corruption while processing user packets to generate page faults.

An issue in assimp v.5.4.3 allows a local attacker to execute arbitrary code via the CallbackToLogRedirector function within the Assimp library.

In the Linux kernel, the following vulnerability has been resolved: smb: client: guarantee refcounted children from parent session Avoid potential use-after-free bugs when walking DFS referrals, mounting and performing DFS failover by ensuring that all children from parent @tcon->ses are also refcounted. They're all needed across the entire DFS mount. Get rid of @tcon->dfs_ses_list while we're at it, too.

Possible use after free due to lack of null check of DRM file status after file structure is freed in Snapdragon Auto, Snapdragon Compute, Snapdragon Connectivity, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Voice & Music, Snapdragon Wearables

In _DevmemXReservationPageAddress of devicemem_server.c, there is a possible use-after-free due to improper casting. This could lead to local escalation of privilege in the kernel with no additional execution privileges needed. User interaction is not needed for exploitation.

Possible use after free when process shell memory is freed using IOCTL call and process initialization is in progress in Snapdragon Auto, Snapdragon Compute, Snapdragon Connectivity, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Voice & Music, Snapdragon Wearables, Snapdragon Wired Infrastructure and Networking

Memory corruption while creating a fence to wait on timeline events, and simultaneously signal timeline events.

Memory corruption when two threads try to map and unmap a single node simultaneously.

Memory corruption as fence object may still be accessed in timeline destruct after isync fence is released.

Memory corruption can occur if VBOs hold outdated or invalid GPU SMMU mappings, especially when the binding and reclaiming of memory buffers are performed at the same time.

An issue was discovered in Samsung Mobile Processor and Wearable Processor Exynos 850, Exynos 1080, Exynos 2100, Exynos 1280, Exynos 1380, Exynos 1330, Exynos W920, Exynos W930. The mobile processor lacks proper memory deallocation checking, which can result in a UAF (Use-After-Free) vulnerability.

Use-after-free vulnerability in win32k.sys in the kernel-mode drivers in Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP1 and SP2, Windows Server 2008 Gold, SP2, R2, and R2 SP1, and Windows 7 Gold and SP1 allows local users to gain privileges via a crafted application that leverages incorrect driver object management, a different vulnerability than other "Vulnerability Type 1" CVEs listed in MS11-034, aka "Win32k Use After Free Vulnerability."
