https://notcve.org/view.php?id=CVE-2024-46761
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. • https://git.kernel.org/stable/c/4eb4085c1346d19d4a05c55246eb93e74e671048 https://git.kernel.org/stable/c/c4c681999d385e28f84808bbf3a85ea8e982da55 https://git.kernel.org/stable/c/bc1faed19db95abf0933b104910a3fb01b138f59 https://git.kernel.org/stable/c/c0d8094dc740cfacf3775bbc6a1c4720459e8de4 https://git.kernel.org/stable/c/438d522227374042b5c8798f8ce83bbe479dca4d https://git.kernel.org/stable/c/b82d4d5c736f4fd2ed224c35f554f50d1953d21e https://git.kernel.org/stable/c/bfc44075b19740d372f989f21dd03168bfda0689 https://git.kernel.org/stable/c/335e35b748527f0c06ded9eebb65387f6 •
CVSS: -EPSS: 0%CPEs: 3EXPL: 0CVE-2024-46760 – wifi: rtw88: usb: schedule rx work after everything is set up
https://notcve.org/view.php?id=CVE-2024-46760
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. • https://git.kernel.org/stable/c/c83d464b82a8ad62ec9077637f75d73fe955635a https://git.kernel.org/stable/c/25eaef533bf3ccc6fee5067aac16f41f280e343e https://git.kernel.org/stable/c/adc539784c98a7cc602cbf557debfc2e7b9be8b3 •
