CVE-2026-46161

A flaw was found in the Linux kernel's md/raid10 module. This vulnerability allows a local user to trigger a divide-by-zero error within the setupgeo function by supplying a malformed layout parameter where the farcopies value is set to zero. Successful exploitation of this flaw can lead to a...

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 ...

SUSE CVE-2026-46050

In the Linux kernel, the following vulnerability has been resolved: md/raid10: fix deadlock with check operation and nowait requests When an array check is running it will raise the barrier at which point normal requests will become blocked and increment the nrpending value to signal there is wor...

Linux kernel 安全漏洞

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the setupgeo function in md raid10 not verifying that farcopies is zero, potentially leading to a zero...

PT-2026-44284

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A divide-by-zero error exists in the setup geo function within the md/raid10 module. The issue occurs when the setup geo function extracts near copies nc and far copies fc from the...

CVE-2026-46050

A flaw was found in the Linux kernel's md/raid10 component. A local user performing a check operation while an application is doing nowait I/O Input/Output on the same array can trigger a deadlock. This occurs because the nrpending value underflows, causing the md resync thread to become stuck...
