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 •
CVSS: 9.1EPSS: 0%CPEs: 8EXPL: 0CVE-2024-35960 – net/mlx5: Properly link new fs rules into the tree
https://notcve.org/view.php?id=CVE-2024-35960
In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Properly link new fs rules into the tree Previously, add_rule_fg would only add newly created rules from the handle into the tree when they had a refcount of 1. On the other hand, create_flow_handle tries hard to find and reference already existing identical rules instead of creating new ones. These two behaviors can result in a situation where create_flow_handle 1) creates a new rule and references it, then 2) in a subsequent step during the same handle creation references it again, resulting in a rule with a refcount of 2 that is not linked into the tree, will have a NULL parent and root and will result in a crash when the flow group is deleted because del_sw_hw_rule, invoked on rule deletion, assumes node->parent is != NULL. This happened in the wild, due to another bug related to incorrect handling of duplicate pkt_reformat ids, which lead to the code in create_flow_handle incorrectly referencing a just-added rule in the same flow handle, resulting in the problem described above. Full details are at [1]. This patch changes add_rule_fg to add new rules without parents into the tree, properly initializing them and avoiding the crash. This makes it more consistent with how rules are added to an FTE in create_flow_handle. • https://git.kernel.org/stable/c/74491de937125d0c98c9b9c9208b4105717a3caa https://git.kernel.org/stable/c/de0139719cdda82806a47580ca0df06fc85e0bd2 https://git.kernel.org/stable/c/1263b0b26077b1183c3c45a0a2479573a351d423 https://git.kernel.org/stable/c/3d90ca9145f6b97b38d0c2b6b30f6ca6af9c1801 https://git.kernel.org/stable/c/7aaee12b804c5e0374e7b132b6ec2158ff33dd64 https://git.kernel.org/stable/c/2e8dc5cffc844dacfa79f056dea88002312f253f https://git.kernel.org/stable/c/5cf5337ef701830f173b4eec00a4f984adeb57a0 https://git.kernel.org/stable/c/adf67a03af39095f05d82050f15813d6f • CWE-476: NULL Pointer Dereference •
