CVE-2025-39684
CVE-2025-39684 affects the Linux kernel Comedi subsystem. The vulnerability arises in do_insn_ioctl() and do_insnlist_ioctl() where a buffer of insn->n samples (unsigned int per sample) could copy back more data to userspace than was initialized, leaking kernel memory. Root cause: not all inst...
CVE-2025-39684 comedi: Fix use of uninitialized memory in do_insn_ioctl() and do_insnlist_ioctl()
In the Linux kernel, the following vulnerability has been resolved: comedi: Fix use of uninitialized memory in doinsnioctl and doinsnlistioctl syzbot reports a KMSAN kernel-infoleak in doinsnioctl. A kernel buffer is allocated to hold insn-n samples each of which is an unsigned int. For some...
