CVE-2026-68154

The CVE-2026-68154 vulnerability affects the Linux kernel’s libceph component, where CRUSH map decoding accepts bucket type 0 (reserved for devices) can let a malformed map cause a negative bucket ID to index the OSD weight array, leading to denial of service. The issue is fixed by rejecting zero...

CVE-2026-68154 libceph: reject zero bucket types in crush_decode

In the Linux kernel, the following vulnerability has been resolved: libceph: reject zero bucket types in crushdecode CRUSH bucket type 0 is reserved for devices. The mapper relies on that invariant and uses type 0 to identify leaf devices. If crushdecode accepts a bucket with type 0, a malformed...
