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: 8.8EPSS: 0%CPEs: 11EXPL: 0CVE-2024-35955 – kprobes: Fix possible use-after-free issue on kprobe registration
https://notcve.org/view.php?id=CVE-2024-35955
In the Linux kernel, the following vulnerability has been resolved: kprobes: Fix possible use-after-free issue on kprobe registration When unloading a module, its state is changing MODULE_STATE_LIVE -> MODULE_STATE_GOING -> MODULE_STATE_UNFORMED. Each change will take a time. `is_module_text_address()` and `__module_text_address()` works with MODULE_STATE_LIVE and MODULE_STATE_GOING. If we use `is_module_text_address()` and `__module_text_address()` separately, there is a chance that the first one is succeeded but the next one is failed because module->state becomes MODULE_STATE_UNFORMED between those operations. In `check_kprobe_address_safe()`, if the second `__module_text_address()` is failed, that is ignored because it expected a kernel_text address. But it may have failed simply because module->state has been changed to MODULE_STATE_UNFORMED. In this case, arm_kprobe() will try to modify non-exist module text address (use-after-free). To fix this problem, we should not use separated `is_module_text_address()` and `__module_text_address()`, but use only `__module_text_address()` once and do `try_module_get(module)` which is only available with MODULE_STATE_LIVE. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: kprobes: soluciona un posible problema de use after free en el registro de kprobe Al descargar un módulo, su estado cambia MODULE_STATE_LIVE -> MODULE_STATE_GOING -> MODULE_STATE_UNFORMED. • https://git.kernel.org/stable/c/1c836bad43f3e2ff71cc397a6e6ccb4e7bd116f8 https://git.kernel.org/stable/c/6a119c1a584aa7a2c6216458f1f272bf1bc93a93 https://git.kernel.org/stable/c/2a49b025c36ae749cee7ccc4b7e456e02539cdc3 https://git.kernel.org/stable/c/a1edb85e60fdab1e14db63ae8af8db3f0d798fb6 https://git.kernel.org/stable/c/28f6c37a2910f565b4f5960df52b2eccae28c891 https://git.kernel.org/stable/c/4262b6eb057d86c7829168c541654fe0d48fdac8 https://git.kernel.org/stable/c/97e813e6a143edf4208e15c72199c495ed80cea5 https://git.kernel.org/stable/c/16a544f1e013ba0660612f3fe35393b14 • CWE-416: Use After Free •

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.
