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 •
CVSS: 5.5EPSS: 0%CPEs: 7EXPL: 0CVE-2024-35950 – drm/client: Fully protect modes[] with dev->mode_config.mutex
https://notcve.org/view.php?id=CVE-2024-35950
In the Linux kernel, the following vulnerability has been resolved: drm/client: Fully protect modes[] with dev->mode_config.mutex The modes[] array contains pointers to modes on the connectors' mode lists, which are protected by dev->mode_config.mutex. Thus we need to extend modes[] the same protection or by the time we use it the elements may already be pointing to freed/reused memory. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/client: Protege completamente los modos[] con dev->mode_config.mutex. La matriz modes[] contiene punteros a los modos en las listas de modos de los conectores, que están protegidos por dev- >mode_config.mutex. Por lo tanto, necesitamos extender modes[] la misma protección o, cuando la usemos, es posible que los elementos ya estén apuntando a la memoria liberada/reutilizada. • https://git.kernel.org/stable/c/5a2f957e3c4553bbb100504a1acfeaeb33f4ca4e https://git.kernel.org/stable/c/41586487769eede64ab1aa6c65c74cbf76c12ef0 https://git.kernel.org/stable/c/d2dc6600d4e3e1453e3b1fb233e9f97e2a1ae949 https://git.kernel.org/stable/c/18c8cc6680ce938d0458859b6a08b4d34f7d8055 https://git.kernel.org/stable/c/04e018bd913d3d3336ab7d21c2ad31a9175fe984 https://git.kernel.org/stable/c/8ceb873d816786a7c8058f50d903574aff8d3764 https://git.kernel.org/stable/c/3eadd887dbac1df8f25f701e5d404d1b90fd0fea https://lists.debian.org/debian-lts-announce/2024/06/ •
