CVE-2026-43087

In the Linux kernel, the following vulnerability has been resolved: pinctrl: mcp23s08: Disable all pin interrupts during probe A chip being probed may have the interrupt-on-change feature enabled on some of its pins, for example after a reboot. This can cause the chip to generate interrupts for...

CVE-2026-43087

The CVE-2026-43087 issue affects the Linux kernel’s pinctrl/mcp23s08 driver. Root cause: during probe, reg_defaults were removed from the regmap, causing the MCP_GPINTEN value to be read from the chip (possibly non-zero) and trigger a nested IRQ handler that may not exist, leading to a kernel cra...

Linux kernel 安全漏洞

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the mcp23s08 chip not disabling all pin interrupts during detection. This could lead to interrupts bein...
