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-2026-46175

A flaw was found in the Linux kernel's f2fs filesystem. During Foreground Garbage Collection FGGC of node blocks, the system fails to properly clear internal metadata marks. This can lead to filesystem inconsistencies, where the fsck utility may misinterpret the state of migrated data. A local us...

CVE-2026-46220

A flaw was found in the Linux kernel's AMDGPU graphics driver drm/amdgpu/sdma4. An unprivileged local user could exploit this vulnerability by submitting specially crafted DRMIOCTLAMDGPUCS commands with misaligned fence writeback addresses. This could trigger a BUGON assertion, leading to a fatal...

CVE-2026-46132

A flaw was found in the Linux kernel's rtnetlink component. The rtnlfillvfinfo function declares a structure on the stack without full initialization. When processing RTMGETLINK requests with a specific attribute, an unprivileged local process can exploit this to read up to 26 bytes of...
