https://notcve.org/view.php?id=CVE-2024-27021
In the Linux kernel, the following vulnerability has been resolved: r8169: fix LED-related deadlock on module removal Binding devm_led_classdev_register() to the netdev is problematic because on module removal we get a RTNL-related deadlock. Fix this by avoiding the device-managed LED functions. Note: We can safely call led_classdev_unregister() for a LED even if registering it failed, because led_classdev_unregister() detects this and is a no-op in this case. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: r8169: corrige el punto muerto relacionado con el LED al eliminar el módulo. Vincular devm_led_classdev_register() al netdev es problemático porque al eliminar el módulo obtenemos un punto muerto relacionado con RTNL. Solucione este problema evitando las funciones LED administradas por el dispositivo. • https://git.kernel.org/stable/c/18764b883e157e28126b54e7d4ba9dd487d5bf54 https://git.kernel.org/stable/c/53d986f39acd8ea11c9e460732bfa5add66360d9 https://git.kernel.org/stable/c/19fa4f2a85d777a8052e869c1b892a2f7556569d • CWE-667: Improper Locking •

In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: Fix potential data-race in __nft_expr_type_get() nft_unregister_expr() can concurrent with __nft_expr_type_get(), and there is not any protection when iterate over nf_tables_expressions list in __nft_expr_type_get(). Therefore, there is potential data-race of nf_tables_expressions list entry. Use list_for_each_entry_rcu() to iterate over nf_tables_expressions list in __nft_expr_type_get(), and use rcu_read_lock() in the caller nft_expr_type_get() to protect the entire type query process. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: netfilter: nf_tables: corrige una posible ejecución de datos en __nft_expr_type_get() nft_unregister_expr() puede concurrente con __nft_expr_type_get(), y no hay ninguna protección cuando se itera sobre la lista nf_tables_expressions en __nft_expr_type_get() . Por lo tanto, existe una posible ejecución de datos en la entrada de la lista nf_tables_expressions. Utilice list_for_each_entry_rcu() para iterar sobre la lista nf_tables_expressions en __nft_expr_type_get() y utilice rcu_read_lock() en el llamador nft_expr_type_get() para proteger todo el proceso de consulta de tipos. • https://git.kernel.org/stable/c/ef1f7df9170dbd875ce198ba84e6ab80f6fc139e https://git.kernel.org/stable/c/939109c0a8e2a006a6cc8209e262d25065f4403a https://git.kernel.org/stable/c/b38a133d37fa421c8447b383d788c9cc6f5cb34c https://git.kernel.org/stable/c/934e66e231cff2b18faa2c8aad0b8cec13957e05 https://git.kernel.org/stable/c/0b6de00206adbbfc6373b3ae38d2a6f197987907 https://git.kernel.org/stable/c/8d56bad42ac4c43c6c72ddd6a654a2628bf839c5 https://git.kernel.org/stable/c/a9ebf340d123ae12582210407f879d6a5a1bc25b https://git.kernel.org/stable/c/01f1a678b05ade4b1248019c2dcca773a • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
