CVE-2026-80951 i3c: master: svc: bound IBI payload to the requested max_payload_len

In the Linux kernel, the following vulnerability has been resolved: i3c: master: svc: bound IBI payload to the requested maxpayloadlen svci3cmasterhandleibi reads the IBI payload from the RX FIFO into the IBI slot. The loop is bounded by the hardware FIFO size SVCI3CFIFOSIZE, not by the slot size...

CVE-2026-80951

CVE-2026-80951 is an out-of-bounds write in the Linux kernel's i3c master svc driver. The function svc_i3c_master_handle_ibi() reads IBI payloads from the RX FIFO, but its loop is bounded by the hardware FIFO size rather than the per-slot max_payload_len . When a device sends more bytes than the ...

CVE-2026-80946

This Linux kernel vulnerability affects the FUSE-io-uring transport. The fuse_request slab cache (fuse_req_cachep) is created without a usercopy whitelist , so directly copying req->in.h to the ring or req->out.h back from the ring trips CONFIG_HARDENED_USERCOPY , triggering a kernel panic ...
