https://notcve.org/view.php?id=CVE-2024-50094
In the Linux kernel, the following vulnerability has been resolved: sfc: Don't invoke xdp_do_flush() from netpoll. Yury reported a crash in the sfc driver originated from netpoll_send_udp(). The netconsole sends a message and then netpoll invokes the driver's NAPI function with a budget of zero. It is dedicated to allow driver to free TX resources, that it may have used while sending the packet. In the netpoll case the driver invokes xdp_do_flush() unconditionally, leading to crash because bpf_net_context was never assigned. Invoke xdp_do_flush() only if budget is not zero. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: sfc: No invoque xdp_do_flush() desde netpoll. Yury informó de un fallo en el controlador sfc originado desde netpoll_send_udp(). • https://git.kernel.org/stable/c/401cb7dae8130fd34eb84648e02ab4c506df7d5e https://git.kernel.org/stable/c/65d4fc76d75c136744e67754d20feda609e7b793 https://git.kernel.org/stable/c/55e802468e1d38dec8e25a2fdb6078d45b647e8c •

https://notcve.org/view.php?id=CVE-2024-50093
In the Linux kernel, the following vulnerability has been resolved: thermal: intel: int340x: processor: Fix warning during module unload The processor_thermal driver uses pcim_device_enable() to enable a PCI device, which means the device will be automatically disabled on driver detach. Thus there is no need to call pci_disable_device() again on it. With recent PCI device resource management improvements, e.g. commit f748a07a0b64 ("PCI: Remove legacy pcim_release()"), this problem is exposed and triggers the warining below.

In the Linux kernel, the following vulnerability has been resolved: net: netconsole: fix wrong warning A warning is triggered when there is insufficient space in the buffer for userdata. However, this is not an issue since userdata will be sent in the next iteration.

In the Linux kernel, the following vulnerability has been resolved: dm vdo: don't refer to dedupe_context after releasing it Clear the dedupe_context pointer in a data_vio whenever ownership of the context is lost, so that vdo can't examine it accidentally. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: dm vdo: no hacer referencia a dedupe_context después de liberarlo. Borre el puntero dedupe_context en un data_vio siempre que se pierda la propiedad del contexto, de modo que vdo no pueda examinarlo accidentalmente. • https://git.kernel.org/stable/c/63ef073084c67878d7a92e15ad055172da3f05a3 https://git.kernel.org/stable/c/0808ebf2f80b962e75741a41ced372a7116f1e26 •
