CVE-2025-38529

CVE-2025-38529 relates to the Linux kernel Comedi driver (aio_iiro_16) where an unchecked userspace-derived value in it->options[1] could cause a shift out of bounds or negative shift; the fix adds a bounds check on it->options[1] before evaluating the (1 <options[1]) & 0xdcfc test. Affe...

UBUNTU-CVE-2025-38482

In the Linux kernel, the following vulnerability has been resolved: comedi: das6402: Fix bit shift out of bounds When checking for a supported IRQ number, the following test is used: / IRQs 2,3,5,6,7, 10,11,15 are valid for "enhanced" mode / if 1 options1 & 0x8cec However, it-optionsi is an...

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->...

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...
