CVE-2026-89656
CVE-2026-89656 is an out-of-bounds write in the libceph subsystem of the Linux kernel . The crush_decode() function stores bucket data by array slot, but a malformed CRUSH map can cause one bucket to alias another's workspace by encoding a mismatched id. When a larger source bucket's permutation ...
