CVE-2026-80951

A flaw was found in the Linux kernel's I3C master driver. A malicious I3C device could exploit this by sending an In-Band Interrupt IBI payload that exceeds the allocated slot size. This can lead to an out-of-bounds write into the IBI pool, potentially causing memory corruption and system...

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 ...
