https://notcve.org/view.php?id=CVE-2024-26752
In the Linux kernel, the following vulnerability has been resolved: l2tp: pass correct message length to ip6_append_data l2tp_ip6_sendmsg needs to avoid accounting for the transport header twice when splicing more data into an already partially-occupied skbuff. To manage this, we check whether the skbuff contains data using skb_queue_empty when deciding how much data to append using ip6_append_data. However, the code which performed the calculation was incorrect: ulen = len + skb_queue_empty(&sk->sk_write_queue) ? transhdrlen : 0; ...due to C operator precedence, this ends up setting ulen to transhdrlen for messages with a non-zero length, which results in corrupted packets on the wire. Add parentheses to correct the calculation in line with the original intent. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: l2tp: pasa la longitud correcta del mensaje a ip6_append_data l2tp_ip6_sendmsg necesita evitar tener en cuenta el encabezado de transporte dos veces al unir más datos en un skbuff ya parcialmente ocupado. Para gestionar esto, verificamos si skbuff contiene datos usando skb_queue_empty al decidir cuántos datos agregar usando ip6_append_data. Sin embargo, el código que realizó el cálculo era incorrecto: ulen = len + skb_queue_empty(&sk->sk_write_queue)? • https://git.kernel.org/stable/c/559d697c5d072593d22b3e0bd8b8081108aeaf59 https://git.kernel.org/stable/c/1fc793d68d50dee4782ef2e808913d5dd880bcc6 https://git.kernel.org/stable/c/96b2e1090397217839fcd6c9b6d8f5d439e705ed https://git.kernel.org/stable/c/cd1189956393bf850b2e275e37411855d3bd86bb https://git.kernel.org/stable/c/f6a7182179c0ed788e3755ee2ed18c888ddcc33f https://git.kernel.org/stable/c/9d4c75800f61e5d75c1659ba201b6c0c7ead3070 https://git.kernel.org/stable/c/7626b9fed53092aa2147978070e610ecb61af844 https://git.kernel.org/stable/c/fe80658c08e3001c80c5533cd41abfbb0 •

In the Linux kernel, the following vulnerability has been resolved: usb: roles: fix NULL pointer issue when put module's reference In current design, usb role class driver will get usb_role_switch parent's module reference after the user get usb_role_switch device and put the reference after the user put the usb_role_switch device. However, the parent device of usb_role_switch may be removed before the user put the usb_role_switch. If so, then, NULL pointer issue will be met when the user put the parent module's reference. This will save the module pointer in structure of usb_role_switch. Then, we don't need to find module by iterating long relations.
