About this tag
The coresight tag on WindowsForum.com covers Linux kernel security vulnerabilities and fixes related to the CoreSight subsystem, which is used for CPU tracing and hardware debug on ARM platforms. Recent discussions include CVE-2025-38131, a race condition in CoreSight configfs handling that could cause a use-after-free and local denial-of-service, and CVE-2023-53261, a memory leak in the CoreSight ACPI parsing path that can degrade system availability. These threads provide technical details on the defects, their impact, and the targeted patches applied by vendors and distributions. The content is relevant for system administrators, kernel developers, and IT professionals managing ARM-based systems or custom kernels that expose CoreSight trace device nodes.

    Linux CoreSight CVE-2025-38131: Fix for Configfs race causing use-after-free

    The Linux kernel has received a targeted fix for CVE-2025-38131 — a race-condition in the CoreSight configfs handling that could allow an active trace configuration to be deactivated while it is being enabled, producing a reliable use‑after‑free (UAF) and a local denial‑of‑service condition...

    Kernel CoreSight ACPI Memory Leak Fixed CVE-2023-53261

    A small, targeted kernel fix patched a creeping memory leak inside the CoreSight ACPI parsing path — a defect that doesn’t expose secrets but can steadily erode system availability by leaking ACPI buffer memory allocated through acpi_buffer->pointer until a service or host runs out of memory...
