| 2024-10-29 | CVE-2024-50070 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: pinctrl: stm32: check devm_kasprintf() returned value devm_kasprintf() can return a NULL pointer on failure but this returned value is not checked. | 5.5 |
| 2024-10-25 | CVE-2024-44101 | NULL Pointer Dereference vulnerability in Google Android there is a possible Null Pointer Dereference (modem crash) due to improper input validation. | 7.5 |
| 2024-10-23 | CVE-2024-10280 | NULL Pointer Dereference vulnerability in Tenda products A vulnerability was found in Tenda AC6, AC7, AC8, AC9, AC10, AC10U, AC15, AC18, AC500 and AC1206 up to 20241022. | 7.5 |
| 2024-10-22 | CVE-2024-40493 | NULL Pointer Dereference vulnerability in Keith-Cullen Freecoap 1.0 Null Pointer Dereference in `coap_client_exchange_blockwise2` function in Keith Cullen FreeCoAP 1.0 allows remote attackers to cause a denial of service and potentially execute arbitrary code via a specially crafted CoAP packet that causes `coap_msg_get_payload(resp)` to return a null pointer, which is then dereferenced in a call to `memcpy`. | 9.8 |
| 2024-10-22 | CVE-2023-52918 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: media: pci: cx23885: check cx23885_vdev_init() return cx23885_vdev_init() can return a NULL pointer, but that pointer is used in the next line without a check. Add a NULL pointer check and go to the error unwind if it is NULL. | 5.5 |
| 2024-10-22 | CVE-2023-52919 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: nfc: nci: fix possible NULL pointer dereference in send_acknowledge() Handle memory allocation failure from nci_skb_alloc() (calling alloc_skb()) to avoid possible NULL pointer dereference. | 5.5 |
| 2024-10-21 | CVE-2022-48953 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: rtc: cmos: Fix event handler registration ordering issue Because acpi_install_fixed_event_handler() enables the event automatically on success, it is incorrect to call it before the handler routine passed to it is ready to handle events. Unfortunately, the rtc-cmos driver does exactly the incorrect thing by calling cmos_wake_setup(), which passes rtc_handler() to acpi_install_fixed_event_handler(), before cmos_do_probe(), because rtc_handler() uses dev_get_drvdata() to get to the cmos object pointer and the driver data pointer is only populated in cmos_do_probe(). This leads to a NULL pointer dereference in rtc_handler() on boot if the RTC fixed event happens to be active at the init time. To address this issue, change the initialization ordering of the driver so that cmos_wake_setup() is always called after a successful cmos_do_probe() call. While at it, change cmos_pnp_probe() to call cmos_do_probe() after the initial if () statement used for computing the IRQ argument to be passed to cmos_do_probe() which is cleaner than calling it in each branch of that if () (local variable "irq" can be of type int, because it is passed to that function as an argument of type int). Note that commit 6492fed7d8c9 ("rtc: rtc-cmos: Do not check ACPI_FADT_LOW_POWER_S0") caused this issue to affect a larger number of systems, because previously it only affected systems with ACPI_FADT_LOW_POWER_S0 set, but it is present regardless of that commit. | 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 |
