CVE-2024-29786Network attack vector

Unauthenticated code execution via unchecked packet address write

Published Jun 13, 2024 · Updated Aug 2, 2024

Out-of-bounds write in Android's CPIF component before the 2024-06-05 patch level allows remote attackers to execute code. pktproc_fill_data_addr_without_bm in link_rx_pktproc.c fills a packet-processing data address without checking destination bounds, permitting an out-of-range write. Network reachability is sufficient; exploitation requires neither authentication nor user interaction.
