CVE-2025-38516

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> pinctrl: qcom: msm: mark certain pins as invalid for interrupts<br /> <br /> On some platforms, the UFS-reset pin has no interrupt logic in TLMM but<br /> is nevertheless registered as a GPIO in the kernel. This enables the<br /> user-space to trigger a BUG() in the pinctrl-msm driver by running, for<br /> example: `gpiomon -c 0 113` on RB2.<br /> <br /> The exact culprit is requesting pins whose intr_detection_width setting<br /> is not 1 or 2 for interrupts. This hits a BUG() in<br /> msm_gpio_irq_set_type(). Potentially crashing the kernel due to an<br /> invalid request from user-space is not optimal, so let&amp;#39;s go through the<br /> pins and mark those that would fail the check as invalid for the irq chip<br /> as we should not even register them as available irqs.<br /> <br /> This function can be extended if we determine that there are more<br /> corner-cases like this.
