CVE-2026-64127

CVE-2026-64127 affects the Linux kernel Bluetooth L2CAP handling. The root cause, after a patch, was an incorrect use of DEFINE_RAW_FLEX() in l2cap_ecred_reconfigure(): the on-stack PDU size and source pointer were not adjusted, causing 8-byte data being copied from the stack instead of the inten...
