AZL-66953 CVE-2025-39684 affecting package kernel for versions less than 6.6.104.2-1

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...

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...

Linux Kernel Security Vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel, which stems from the use of uninitialized memory by the comedi module in doinsnioctl and doinsnlistioctl...

DEBIAN-CVE-2025-38478

In the Linux kernel, the following vulnerability has been resolved: comedi: Fix initialization of data for instructions that write to subdevice Some Comedi subdevice instruction handlers are known to access instruction data elements beyond the first insn-n elements in some cases. The doinsnioctl...
