https://notcve.org/view.php?id=CVE-2024-26828
In the Linux kernel, the following vulnerability has been resolved: cifs: fix underflow in parse_server_interfaces() In this loop, we step through the buffer and after each item we check if the size_left is greater than the minimum size we need. However, the problem is that "bytes_left" is type ssize_t while sizeof() is type size_t. That means that because of type promotion, the comparison is done as an unsigned and if we have negative bytes left the loop continues instead of ending. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: cifs: corrige el desbordamiento insuficiente en parse_server_interfaces() En este bucle, recorremos el búfer y después de cada elemento comprobamos si size_left es mayor que el tamaño mínimo que necesitamos. Sin embargo, el problema es que "bytes_left" es del tipo ssize_t mientras que sizeof() es del tipo size_t. • https://git.kernel.org/stable/c/fe856be475f7cf5ffcde57341d175ce9fd09434b https://git.kernel.org/stable/c/7190353835b4a219abb70f90b06cdcae97f11512 https://git.kernel.org/stable/c/f7ff1c89fb6e9610d2b01c1821727729e6609308 https://git.kernel.org/stable/c/df2af9fdbc4ddde18a3371c4ca1a86596e8be301 https://git.kernel.org/stable/c/cffe487026be13eaf37ea28b783d9638ab147204 https://access.redhat.com/security/cve/CVE-2024-26828 https://bugzilla.redhat.com/show_bug.cgi?id=2275600 • CWE-191: Integer Underflow (Wrap or Wraparound) •
CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-26825 – nfc: nci: free rx_data_reassembly skb on NCI device cleanup
https://notcve.org/view.php?id=CVE-2024-26825
In the Linux kernel, the following vulnerability has been resolved: nfc: nci: free rx_data_reassembly skb on NCI device cleanup rx_data_reassembly skb is stored during NCI data exchange for processing fragmented packets. It is dropped only when the last fragment is processed or when an NTF packet with NCI_OP_RF_DEACTIVATE_NTF opcode is received. However, the NCI device may be deallocated before that which leads to skb leak. As by design the rx_data_reassembly skb is bound to the NCI device and nothing prevents the device to be freed before the skb is processed in some way and cleaned, free it on the NCI device cleanup. Found by Linux Verification Center (linuxtesting.org) with Syzkaller. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: nfc: nci: rx_data_reassembly skb gratuito en la limpieza del dispositivo NCI rx_data_reassembly skb se almacena durante el intercambio de datos NCI para procesar paquetes fragmentados. Se elimina solo cuando se procesa el último fragmento o cuando se recibe un paquete NTF con el código de operación NCI_OP_RF_DEACTIVATE_NTF. Sin embargo, el dispositivo NCI puede desasignarse antes de lo que provoca una fuga de skb. • https://git.kernel.org/stable/c/6a2968aaf50c7a22fced77a5e24aa636281efca8 https://git.kernel.org/stable/c/7e9a8498658b398bf11b8e388005fa54e40aed81 https://git.kernel.org/stable/c/71349abe3aba7fedcab5b3fcd7aa82371fb5ccbf https://git.kernel.org/stable/c/2f6d16f0520d6505241629ee2f5c131b547d5f9d https://git.kernel.org/stable/c/471c9ede8061357b43a116fa692e70d91941ac23 https://git.kernel.org/stable/c/5c0c5ffaed73cbae6c317374dc32ba6cacc60895 https://git.kernel.org/stable/c/16d3f507b0fa70453dc54550df093d6e9ac630c1 https://git.kernel.org/stable/c/a3d90fb5c23f29ba59c04005ae76c5228 •
CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-26820 – hv_netvsc: Register VF in netvsc_probe if NET_DEVICE_REGISTER missed
https://notcve.org/view.php?id=CVE-2024-26820
In the Linux kernel, the following vulnerability has been resolved: hv_netvsc: Register VF in netvsc_probe if NET_DEVICE_REGISTER missed If hv_netvsc driver is unloaded and reloaded, the NET_DEVICE_REGISTER handler cannot perform VF register successfully as the register call is received before netvsc_probe is finished. This is because we register register_netdevice_notifier() very early( even before vmbus_driver_register()). To fix this, we try to register each such matching VF( if it is visible as a netdevice) at the end of netvsc_probe. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: hv_netvsc: registre VF en netvsc_probe si se perdió NET_DEVICE_REGISTER. Si el controlador hv_netvsc se descarga y se vuelve a cargar, el controlador NET_DEVICE_REGISTER no puede realizar el registro VF exitosamente ya que la llamada de registro se recibe antes de que finalice netvsc_probe. Esto se debe a que registramos Register_netdevice_notifier() muy temprano (incluso antes de vmbus_driver_register()). • https://git.kernel.org/stable/c/028aa21f9e92536038cabb834c15d08f5c894382 https://git.kernel.org/stable/c/997d895fa495fb3421983923219bba93f1a793ee https://git.kernel.org/stable/c/ff6c130e48a79c826cbc2427bd8b34a7592460cc https://git.kernel.org/stable/c/97683466e24c801ee4e865ce90ac7e355db2da59 https://git.kernel.org/stable/c/5dd83db613be8e5c5d30efed7f42780e9eb18380 https://git.kernel.org/stable/c/7350c460f7f48a8653a15c5c90fc9070aaa29535 https://git.kernel.org/stable/c/85520856466ed6bc3b1ccb013cddac70ceb437db https://git.kernel.org/stable/c/bcb7164258d0a9a8aa2e73ddccc2d78f6 •
