CVE-2026-74429: Linux

Описание

Оригинално описание

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix the reception of a reply packet before data transmission Fix rxrpc_receiving_reply() to handle the reception of an apparent reply DATA packet before rxrpc has had a chance to send any request DATA packets on a client call by checking to see if the call has been exposed yet by sending the first packet. Without this, rxrpc_rotate_tx_window() might oops. Also fix rxrpc_rotate_tx_window() to handle the Tx queue being empty by changing the do...while loop into a while loop, just in case a call is abnormally terminated by an early reply before the last request packet is transmitted.
