| CVE-2022-49029 | 2024-10-21 | N/A | N/A | ||
| In the Linux kernel, the following vulnerability has been resolved: hwmon: (ibmpex) Fix possible UAF when ibmpex_register_bmc() fails Smatch report warning as follows: drivers/hwmon/ibmpex.c:509 ibmpex_register_bmc() warn: '&data->list' not removed from list If ibmpex_find_sensors() fails in ibmpex_register_bmc(), data will be freed, but data->list will not be removed from driver_data.bmc_data, then list traversal may cause UAF. Fix by removeing it from driver_data.bmc_data before free(). | |||||
| CVE-2022-49028 | 2024-10-21 | N/A | N/A | ||
| In the Linux kernel, the following vulnerability has been resolved: ixgbevf: Fix resource leak in ixgbevf_init_module() ixgbevf_init_module() won't destroy the workqueue created by create_singlethread_workqueue() when pci_register_driver() failed. Add destroy_workqueue() in fail path to prevent the resource leak. Similar to the handling of u132_hcd_init in commit f276e002793c ("usb: u132-hcd: fix resource leak") | |||||
| CVE-2022-49027 | 2024-10-21 | N/A | N/A | ||
| In the Linux kernel, the following vulnerability has been resolved: iavf: Fix error handling in iavf_init_module() The iavf_init_module() won't destroy workqueue when pci_register_driver() failed. Call destroy_workqueue() when pci_register_driver() failed to prevent the resource leak. Similar to the handling of u132_hcd_init in commit f276e002793c ("usb: u132-hcd: fix resource leak") | |||||
| CVE-2022-49026 | 2024-10-21 | N/A | N/A | ||
| In the Linux kernel, the following vulnerability has been resolved: e100: Fix possible use after free in e100_xmit_prepare In e100_xmit_prepare(), if we can't map the skb, then return -ENOMEM, so e100_xmit_frame() will return NETDEV_TX_BUSY and the upper layer will resend the skb. But the skb is already freed, which will cause UAF bug when the upper layer resends the skb. Remove the harmful free. | |||||

| In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix use-after-free when reverting termination table When having multiple dests with termination tables and second one or afterwards fails the driver reverts usage of term tables but doesn't reset the assignment in attr->dests[num_vport_dests].termtbl which case a use-after-free when releasing the rule. Fix by resetting the assignment of termtbl to null. | |||||

| CVE-2022-49020 | 2024-10-21 | N/A | N/A | ||
| In the Linux kernel, the following vulnerability has been resolved: net/9p: Fix a potential socket leak in p9_socket_open Both p9_fd_create_tcp() and p9_fd_create_unix() will call p9_socket_open(). If the creation of p9_trans_fd fails, p9_fd_create_tcp() and p9_fd_create_unix() will return an error directly instead of releasing the cscoket, which will result in a socket leak. This patch adds sock_release() to fix the leak issue. | |||||

So call fwnode_handle_put() in phy_device_release() to avoid leak. If it's an acpi node, it has never been get, but it's put in the error path, so call fwnode_handle_get() before phy_device_register() to keep get/put operation balanced. | |||||
