CVE-2025-39686

CVE-2025-39686: In the Linux kernel comedi subsystem, insn_rw_emulate_bits() incorrectly emulated INSN_READ/WRITE for subdevices that support INSN_BITS, handling only a single sample instead of insn->n samples. The fix is to make the function process all n samples or return an error to conform...

CVE-2025-39685

Summary (CVE-2025-39685) : In the Linux kernel, the comedi pcl726 driver could trigger an out-of-bounds when an excessively large IRQ number was passed (example 0x80008000). The fix adds an interrupt number check to prevent passing an IRQ number that is too large. It notes that if it->options[...
