Remote Code Execution via UI Designer Form File in Safe Mode

In JetBrains IntelliJ IDEA before 2026.3 code execution was possible in Safe Mode via UI Designer form file

In multiple locations, there is a possible out of bounds write due to an integer overflow. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

Unprompted URL Opening via Remote Development Port Forwarding

In JetBrains IntelliJ IDEA before 2026.3 opening arbitrary URLs without confirmation was possible via the Remote Development port forwarding model

Incorrect default permissions on session transcripts and prompt history in Kiro CLI

Incorrect default file permissions in Kiro CLI (formerly Amazon Q Developer CLI) before version 2.27.0 on macOS and Linux might allow other local users on the same host to read a user's session transcripts and prompt history, including any credentials or source code they contain. The CLI created its local session storage files with permissions that made them readable by all local users. To remediate this issue, users should upgrade to Kiro CLI version 2.27.0 or later and launch it once. Users who ran Amazon Q Developer CLI 1.16.0 through 1.19.x should also delete the ~/.aws/amazonq/.cli_bash_history file or restrict it to the owner.

Double free in kvm_vfio_pviommu_attach allows local privilege escalation

In kvm_vfio_pviommu_attach of vfio.c, there is a possible double free due to a logic error in the code. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

Local Privilege Escalation in Android NFC Service Through Permission Check Bypass

In multiple functions of NfcService.java, there is a possible permission bypass due to a missing permission check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

The vulnerability is a Use-After-Free (UAF) in the EVS AIDL HAL, arising from a data race on an unsynchronized `std::weak_ptr` within `EvsEnumerator::openCamera()`. Specifically, concurrent calls from a privileged UID (e.g., `AID_AUTOMOTIVE_EVS`) can cause a torn `weak_ptr` state, leading to a virtual call through a freed object's vtable at `cameraObj->getCameraInfo(&desc)`. This allows for potential arbitrary code execution within the `hal_evs_default` process.

An unprivileged application can exploit a lack of package/signature validation in SystemUI's `RemoteQCController` when resolving a hardcoded `content://` URI. This allows the attacker to squat on a specific authority if the legitimate package is absent, inject spoofed UI elements into the trusted SystemUI Quick Controls panel, and gain a Background Activity Launch (BAL) grant from SystemUI when the user interacts with the spoofed element.

In is_valid_header of timed_cache_item.c, there is a possible out-of-bounds write due to a missing bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.
