CVE-2025-40106

In the Linux kernel, the following vulnerability has been resolved: comedi: fix divide-by-zero in comedibufmunge The comedibufmunge function performs a modulo operation async-mungechan %= async-cmd.chanlistlen without first checking if chanlistlen is zero. If a user program submits a command with...

CVE-2025-40106

In CVE-2025-40106, the Linux kernel’s comedi_buf_munge() could divide by zero when chanlist_len is zero, since it performed async->munge_chan %= async->cmd.chanlist_len without a prior check. The fix adds an explicit zero-check at the start of comedi_buf_munge(), mirrors existing checks for...
