CVE-2026-53151

CVE-2026-53151 concerns the Linux kernel AF_RXRPC subsystem, where legacy parsing of the SACK table could trigger an invalid buffer access when processing fragmented UDP packets. The fix updates rxrpc_input_soft_acks() and rxrpc_input_ack() logic so that SACK contents are not copied into a flat b...
