About this tag
CVE-2025-68233 is a Linux kernel vulnerability affecting the Tegra DRM driver. It involves a PID reference leak in the host1x_memory_context_alloc function, where a call to get_task_pid was not matched with a corresponding put_pid. This oversight can cause kernel PID references to accumulate over time, potentially leading to resource exhaustion on systems using NVIDIA Tegra hardware. The fix, a one-line patch adding the missing put_pid call, was published in mid-December 2025. This tag covers discussions about the vulnerability, its impact on Linux kernel stability, and the patch that resolves it.

    CVE-2025-68233: Tegra DRM PID Leak Fixed in Linux Kernel

    A small but important Linux kernel fix published in mid‑December 2025 addresses a resource‑leak in the Tegra DRM driver by adding a missing call to put_pid, closing a PID ownership gap in host1x_memory_context_alloc that could otherwise accumulate kernel PID references over time and lead to...
