CVE-2026-64192

CVE-2026-64192 affects the Linux kernel (BPF inode storage maps). When CONFIG_BPF_LSM=y and the BPF LSM is not enabled at boot, lsm_prepare() doesn’t run, so the BPF LSM blob size (lbs_inode) remains at the compiled default (8 bytes) instead of a larger offset. This lets a privileged user create/...
