| 2024-09-18 | CVE-2024-46760 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: wifi: rtw88: usb: schedule rx work after everything is set up Right now it's possible to hit NULL pointer dereference in rtw_rx_fill_rx_status on hw object and/or its fields because initialization routine can start getting USB replies before rtw_dev is fully setup. The stack trace looks like this: rtw_rx_fill_rx_status rtw8821c_query_rx_desc rtw_usb_rx_handler ... queue_work rtw_usb_read_port_complete ... usb_submit_urb rtw_usb_rx_resubmit rtw_usb_init_rx rtw_usb_probe So while we do the async stuff rtw_usb_probe continues and calls rtw_register_hw, which does all kinds of initialization (e.g. via ieee80211_register_hw) that rtw_rx_fill_rx_status relies on. Fix this by moving the first usb_submit_urb after everything is set up. For me, this bug manifested as: [ 8.893177] rtw_8821cu 1-1:1.2: band wrong, packet dropped [ 8.910904] rtw_8821cu 1-1:1.2: hw->conf.chandef.chan NULL in rtw_rx_fill_rx_status because I'm using Larry's backport of rtw88 driver with the NULL checks in rtw_rx_fill_rx_status. | 5.5 |
| 2024-09-18 | CVE-2024-46761 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: pci/hotplug/pnv_php: Fix hotplug driver crash on Powernv The hotplug driver for powerpc (pci/hotplug/pnv_php.c) causes a kernel crash when we try to hot-unplug/disable the PCIe switch/bridge from the PHB. The crash occurs because although the MSI data structure has been released during disable/hot-unplug path and it has been assigned with NULL, still during unregistration the code was again trying to explicitly disable the MSI which causes the NULL pointer dereference and kernel crash. The patch fixes the check during unregistration path to prevent invoking pci_disable_msi/msix() since its data structure is already freed. | 5.5 |
| 2024-09-18 | CVE-2024-46762 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: xen: privcmd: Fix possible access to a freed kirqfd instance Nothing prevents simultaneous ioctl calls to privcmd_irqfd_assign() and privcmd_irqfd_deassign(). | 5.5 |
| 2024-09-18 | CVE-2024-46763 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: fou: Fix null-ptr-deref in GRO. We observed a null-ptr-deref in fou_gro_receive() while shutting down a host. | 5.5 |
| 2024-09-18 | CVE-2024-46765 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ice: protect XDP configuration with a mutex The main threat to data consistency in ice_xdp() is a possible asynchronous PF reset. | 5.5 |
| 2024-09-18 | CVE-2024-46766 | Out-of-bounds Write vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ice: move netif_queue_set_napi to rtnl-protected sections Currently, netif_queue_set_napi() is called from ice_vsi_rebuild() that is not rtnl-locked when called from the reset. | 7.8 |
| 2024-09-18 | CVE-2024-46768 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: hwmon: (hp-wmi-sensors) Check if WMI event data exists The BIOS can choose to return no event data in response to a WMI event, so the ACPI object passed to the WMI notify handler can be NULL. Check for such a situation and ignore the event in such a case. | 5.5 |
| 2024-09-18 | CVE-2024-46769 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: spi: intel: Add check devm_kasprintf() returned value intel_spi_populate_chip() use devm_kasprintf() to set pdata->name. This can return a NULL pointer on failure but this returned value is not checked. | 5.5 |
| 2024-09-18 | CVE-2024-46770 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ice: Add netif_device_attach/detach into PF reset flow Ethtool callbacks can be executed while reset is in progress and try to access deleted resources, e.g. | 5.5 |
| 2024-09-18 | CVE-2024-46771 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: can: bcm: Remove proc entry when dev is unregistered. syzkaller reported a warning in bcm_connect() below. | 5.5 |
