| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 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-2022-49450 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix listen() setting the bar too high for the prealloc rings AF_RXRPC's listen() handler lets you set the backlog up to 32 (if you bump up the sysctl), but whilst the preallocation circular buffers have 32 slots in them, one of them has to be a dead slot because we're using CIRC_CNT(). This means that listen(rxrpc_sock, 32) will cause an oops when the socket is closed because rxrpc_service_prealloc_one() allocated one too many calls and rxrpc_discard_prealloc() won't then be able to get rid of them because it'll think the ring is empty. | 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-2022-49467 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm: msm: fix possible memory leak in mdp5_crtc_cursor_set() drm_gem_object_lookup will call drm_gem_object_get inside. | 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 |
| 2025-02-26 | CVE-2022-49481 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: regulator: pfuze100: Fix refcount leak in pfuze_parse_regulators_dt of_node_get() returns a node with refcount incremented. Calling of_node_put() to drop the reference when not needed anymore. | 5.5 |
| 2025-02-26 | CVE-2022-49482 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ASoC: mxs-saif: Fix refcount leak in mxs_saif_probe of_parse_phandle() returns a node pointer with refcount incremented, we should use of_node_put() on it when done. | 5.5 |
