26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: can: mcba_usb: properly check endpoint type Syzbot reported warning in usb_submit_urb() which is caused by wrong endpoint type. We should check that in endpoint is actually present to prevent this warning. Found pipes are now saved to struct mcba_priv and code uses them directly instead of making pipes in place.

26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix call timer start racing with call destruction The rxrpc_call struct has a timer used to handle various timed events relating to a call. This timer can get started from the packet input routines that are run in softirq mode with just the RCU read lock held. Unfortunately, because only the RCU read lock is held - and neither ref or other lock is taken - the call can start getting destroyed at the same time a packet comes in address... • https://git.kernel.org/stable/c/a158bdd3247b9656df36ba133235fff702e9fdc3 •

26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_event: Ignore multiple conn complete events When one of the three connection complete events is received multiple times for the same handle, the device is registered multiple times which leads to memory corruptions. Therefore, consequent events for a single connection are ignored. The conn->state can hold different values, therefore HCI_CONN_HANDLE_UNSET is introduced to identify new connections.
