CVE-2025-38482

CVE-2025-38482 : In the Linux kernel, the comedi das6402 IRQ check used an unchecked user-supplied value for the shift amount, allowing a negative or out-of-range shift. The test now requires it->options[1] to be within bounds before applying the test, with valid IRQ values in [1,15] and 0 dis...

CVE-2025-38483

CVE-2025-38483 concerns the Linux kernel’s comedi das16m1 IRQ validation. The test for valid IRQs uses a bitmask check on (1 <options[1]), but it->options[i] is an unchecked int from userspace, allowing the shift amount to be negative or out of bounds. The fix adds a bounds check on it->...
