CVSS: 5.5EPSS: 0%CPEs: 6EXPL: 0CVE-2024-27431 – cpumap: Zero-initialise xdp_rxq_info struct before running XDP program
https://notcve.org/view.php?id=CVE-2024-27431
In the Linux kernel, the following vulnerability has been resolved: cpumap: Zero-initialise xdp_rxq_info struct before running XDP program When running an XDP program that is attached to a cpumap entry, we don't initialise the xdp_rxq_info data structure being used in the xdp_buff that backs the XDP program invocation. Tobias noticed that this leads to random values being returned as the xdp_md->rx_queue_index value for XDP programs running in a cpumap. This means we're basically returning the contents of the uninitialised memory, which is bad. Fix this by zero-initialising the rxq data structure before running the XDP program. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: cpumap: Inicializa a cero la estructura xdp_rxq_info antes de ejecutar el programa XDP Cuando ejecutas un programa XDP que está adjunto a una entrada de cpumap, no inicializamos la estructura de datos xdp_rxq_info que se utiliza en xdp_buff que respalda la invocación del programa XDP. Tobias notó que esto lleva a que se devuelvan valores aleatorios como el valor xdp_md->rx_queue_index para programas XDP que se ejecutan en un cpumap. • https://git.kernel.org/stable/c/9216477449f33cdbc9c9a99d49f500b7fbb81702 https://git.kernel.org/stable/c/5f4e51abfbe6eb444fa91906a5cd083044278297 https://git.kernel.org/stable/c/f0363af9619c77730764f10360e36c6445c12f7b https://git.kernel.org/stable/c/3420b3ff1ff489c177ea1cb7bd9fbbc4e9a0be95 https://git.kernel.org/stable/c/f562e4c4aab00986dde3093c4be919c3f2b85a4a https://git.kernel.org/stable/c/eaa7cb836659ced2d9f814ac32aa3ec193803ed6 https://git.kernel.org/stable/c/2487007aa3b9fafbd2cb14068f49791ce1d7ede5 https://lists.debian.org/debian-lts-announce/2024/06/ • CWE-908: Use of Uninitialized Resource •

https://notcve.org/view.php?id=CVE-2024-27418
In the Linux kernel, the following vulnerability has been resolved: net: mctp: take ownership of skb in mctp_local_output Currently, mctp_local_output only takes ownership of skb on success, and we may leak an skb if mctp_local_output fails in specific states; the skb ownership isn't transferred until the actual output routing occurs. Instead, make mctp_local_output free the skb on all error paths up to the route action, so it always consumes the passed skb. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: net: mctp: toma posesión de skb en mctp_local_output Actualmente, mctp_local_output solo toma propiedad de skb en caso de éxito, y podemos filtrar un fallo skb si mctp_local_output en estados específicos; la propiedad del skb no se transfiere hasta que se produce el enrutamiento de salida real. En su lugar, haga que mctp_local_output libere el skb en todas las rutas de error hasta la acción de ruta, de modo que siempre consuma el skb pasado. • https://git.kernel.org/stable/c/833ef3b91de692ef33b800bca6b1569c39dece74 https://git.kernel.org/stable/c/a3c8fa54e904b0ddb52a08cc2d8ac239054f61fd https://git.kernel.org/stable/c/cbebc55ceacef1fc0651e80e0103cc184552fc68 https://git.kernel.org/stable/c/a639441c880ac479495e5ab37e3c29f21ae5771b https://git.kernel.org/stable/c/3773d65ae5154ed7df404b050fd7387a36ab5ef3 •
