https://notcve.org/view.php?id=CVE-2024-35962
In the Linux kernel, the following vulnerability has been resolved: netfilter: complete validation of user input In my recent commit, I missed that do_replace() handlers use copy_from_sockptr() (which I fixed), followed by unsafe copy_from_sockptr_offset() calls. In all functions, we can perform the @optlen validation before even calling xt_alloc_table_info() with the following check: if ((u64)optlen < (u64)tmp.size + sizeof(tmp)) return -EINVAL; En el kernel de Linux, se resolvió la siguiente vulnerabilidad: netfilter: validación completa de la entrada del usuario En mi confirmación reciente, omití que los controladores do_replace() usan copy_from_sockptr() (que arreglé), seguido de llamadas inseguras copy_from_sockptr_offset(). En todas las funciones, podemos realizar la validación @optlen incluso antes de llamar a xt_alloc_table_info() con la siguiente comprobación: if ((u64)optlen < (u64)tmp.size + sizeof(tmp)) return -EINVAL; • https://git.kernel.org/stable/c/0f038242b77ddfc505bf4163d4904c1abd2e74d6 https://git.kernel.org/stable/c/440e948cf0eff32cfe322dcbca3f2525354b159b https://git.kernel.org/stable/c/18aae2cb87e5faa9c5bd865260ceadac60d5a6c5 https://git.kernel.org/stable/c/81d51b9b7c95e791ba3c1a2dd77920a9d3b3f525 https://git.kernel.org/stable/c/58f2bfb789e6bd3bc24a2c9c1580f3c67aec3018 https://git.kernel.org/stable/c/cf4bc359b76144a3dd55d7c09464ef4c5f2b2b05 https://git.kernel.org/stable/c/97dab36e57c64106e1c8ebd66cbf0d2d1e52d6b7 https://git.kernel.org/stable/c/c760089aa98289b4b88a7ff5a62dd9284 •

https://notcve.org/view.php?id=CVE-2024-35961
In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Register devlink first under devlink lock In case device is having a non fatal FW error during probe, the driver will report the error to user via devlink. This will trigger a WARN_ON, since mlx5 is calling devlink_register() last. In order to avoid the WARN_ON[1], change mlx5 to invoke devl_register() first under devlink lock.
