| 2024-10-21 | CVE-2022-48959 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: dsa: sja1105: fix memory leak in sja1105_setup_devlink_regions() When dsa_devlink_region_create failed in sja1105_setup_devlink_regions(), priv->regions is not released. | 5.5 |
| 2024-10-21 | CVE-2022-48961 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: mdio: fix unbalanced fwnode reference count in mdio_device_release() There is warning report about of_node refcount leak while probing mdio device: OF: ERROR: memory leak, expected refcount 1 instead of 2, of_node_get()/of_node_put() unbalanced - destroy cset entry: attach overlay node /spi/soc@0/mdio@710700c0/ethernet@4 In of_mdiobus_register_device(), we increase fwnode refcount by fwnode_handle_get() before associating the of_node with mdio device, but it has never been decreased in normal path. Since that, in mdio_device_release(), it needs to call fwnode_handle_put() in addition instead of calling kfree() directly. After above, just calling mdio_device_free() in the error handle path of of_mdiobus_register_device() is enough to keep the refcount balanced. | 5.5 |
| 2024-10-21 | CVE-2022-48963 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: wwan: iosm: fix memory leak in ipc_mux_init() When failed to alloc ipc_mux->ul_adb.pp_qlt in ipc_mux_init(), ipc_mux is not released. | 5.5 |
| 2024-10-21 | CVE-2022-48965 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: gpio/rockchip: fix refcount leak in rockchip_gpiolib_register() The node returned by of_get_parent() with refcount incremented, of_node_put() needs be called when finish using it. | 5.5 |
| 2024-10-21 | CVE-2022-48968 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: octeontx2-pf: Fix potential memory leak in otx2_init_tc() In otx2_init_tc(), if rhashtable_init() failed, it does not free tc->tc_entries_bitmap which is allocated in otx2_tc_alloc_ent_bitmap(). | 5.5 |
| 2024-10-21 | CVE-2022-48969 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: xen-netfront: Fix NULL sring after live migration A NAPI is setup for each network sring to poll data to kernel The sring with source host is destroyed before live migration and new sring with target host is setup after live migration. The NAPI for the old sring is not deleted until setup new sring with target host after migration. | 5.5 |
| 2024-10-21 | CVE-2022-48970 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: af_unix: Get user_ns from in_skb in unix_diag_get_exact(). Wei Chen reported a NULL deref in sk_user_ns() [0][1], and Paolo diagnosed the root cause: in unix_diag_get_exact(), the newly allocated skb does not have sk. | 5.5 |
| 2024-10-21 | CVE-2022-48971 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: Bluetooth: Fix not cleanup led when bt_init fails bt_init() calls bt_leds_init() to register led, but if it fails later, bt_leds_cleanup() is not called to unregister it. This can cause panic if the argument "bluetooth-power" in text is freed and then another led_trigger_register() tries to access it: BUG: unable to handle page fault for address: ffffffffc06d3bc0 RIP: 0010:strcmp+0xc/0x30 Call Trace: <TASK> led_trigger_register+0x10d/0x4f0 led_trigger_register_simple+0x7d/0x100 bt_init+0x39/0xf7 [bluetooth] do_one_initcall+0xd0/0x4e0 | 5.5 |
| 2024-10-21 | CVE-2022-48972 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mac802154: fix missing INIT_LIST_HEAD in ieee802154_if_add() Kernel fault injection test reports null-ptr-deref as follows: BUG: kernel NULL pointer dereference, address: 0000000000000008 RIP: 0010:cfg802154_netdev_notifier_call+0x120/0x310 include/linux/list.h:114 Call Trace: <TASK> raw_notifier_call_chain+0x6d/0xa0 kernel/notifier.c:87 call_netdevice_notifiers_info+0x6e/0xc0 net/core/dev.c:1944 unregister_netdevice_many_notify+0x60d/0xcb0 net/core/dev.c:1982 unregister_netdevice_queue+0x154/0x1a0 net/core/dev.c:10879 register_netdevice+0x9a8/0xb90 net/core/dev.c:10083 ieee802154_if_add+0x6ed/0x7e0 net/mac802154/iface.c:659 ieee802154_register_hw+0x29c/0x330 net/mac802154/main.c:229 mcr20a_probe+0xaaa/0xcb1 drivers/net/ieee802154/mcr20a.c:1316 ieee802154_if_add() allocates wpan_dev as netdev's private data, but not init the list in struct wpan_dev. | 5.5 |
