| 2025-02-26 | CVE-2022-49438 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: Input: sparcspkr - fix refcount leak in bbc_beep_probe of_find_node_by_path() calls of_find_node_opts_by_path(), which returns a node pointer with refcount incremented, we should use of_node_put() on it when done. Add missing of_node_put() to avoid refcount leak. | 5.5 |
| 2025-02-26 | CVE-2022-49447 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ARM: hisi: Add missing of_node_put after of_find_compatible_node of_find_compatible_node will increment the refcount of the returned device_node. | 5.5 |
| 2025-02-26 | CVE-2022-49449 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: pinctrl: renesas: rzn1: Fix possible null-ptr-deref in sh_pfc_map_resources() It will cause null-ptr-deref when using 'res', if platform_get_resource() returns NULL, so move using 'res' after devm_ioremap_resource() that will check it to avoid null-ptr-deref. And use devm_platform_get_and_ioremap_resource() to simplify code. | 5.5 |
| 2025-02-26 | CVE-2022-49453 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: soc: ti: ti_sci_pm_domains: Check for null return of devm_kcalloc The allocation funciton devm_kcalloc may fail and return a null pointer, which would cause a null-pointer dereference later. It might be better to check it and directly return -ENOMEM just like the usage of devm_kcalloc in previous code. | 5.5 |
| 2025-02-26 | CVE-2022-49457 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ARM: versatile: Add missing of_node_put in dcscb_init The device_node pointer is returned by of_find_compatible_node with refcount incremented. | 5.5 |
| 2025-02-26 | CVE-2022-49471 | Improper Validation of Array Index vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: rtw89: cfo: check mac_id to avoid out-of-bounds Somehow, hardware reports incorrect mac_id and pollute memory. | 7.8 |
| 2025-02-26 | CVE-2022-49472 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: phy: micrel: Allow probing without .driver_data Currently, if the .probe element is present in the phy_driver structure and the .driver_data is not, a NULL pointer dereference happens. Allow passing .probe without .driver_data by inserting NULL checks for priv->type. | 5.5 |
| 2025-02-26 | CVE-2022-49478 | Improper Validation of Array Index vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: media: pvrusb2: fix array-index-out-of-bounds in pvr2_i2c_core_init Syzbot reported that -1 is used as array index. | 7.8 |
