CVE-2026-46161

In the Linux kernel, the following vulnerability has been resolved: md/raid10: fix divide-by-zero in setupgeo with zero farcopies setupgeo extracts nearcopies nc and farcopies fc from the user-provided layout parameter without checking for zero. When fc=0 with the "improved" far set layout...

CVE-2026-46161

CVE-2026-46161 affects the Linux kernel md/raid10 code: setup_geo() may divide by zero when fc (far copies) is 0, since it derives geo->far_set_size from disks/fc without validating zero. The fix validates nc and fc after extraction and returns -1 if either is zero. Connected OSV entries show ...
