How to fix?

Upgrade torvalds/linux to version 6.1.191, 6.6.130, 6.12.69, 6.18.8 or higher.

Overview

Affected versions of this package are vulnerable to Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') in the rxrpc_peer_keepalive_worker process due to lockless accesses to the last_tx_at field, which can result in data races and potential load/store tearing, especially on 32-bit architectures. An attacker can cause inconsistent state or unexpected behavior by triggering concurrent operations that access or modify the last_tx_at value.

Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
