CVE-2023-53119

CVE-2023-53119 : In the Linux kernel, the pn533 NFC driver (pn533_out_arg) uses a temporary context for out_urb that is not fully initialized; the uninitialized field ‘phy’ may be dereferenced in error paths inside pn533_out_complete(), causing a general protection fault and a KASAN null-deref. T...

CVE-2023-53102 ice: xsk: disable txq irq before flushing hw

In the Linux kernel, the following vulnerability has been resolved: ice: xsk: disable txq irq before flushing hw iceqpdis intends to stop a given queue pair that is a target of xsk pool attach/detach. One of the steps is to disable interrupts on these queues. It currently is broken in a way that...

CVE-2023-53102

Summary of CVE-2023-53102 (Linux kernel ice driver, AF_XDP/XSK): The issue arises in ice_qp_dis() when stopping a queue pair used by xsk pool attach/detach. TXQ interrupts were not reliably disabled before the hardware flush, allowing NAPI to run and freeing xdp_buff pointers prematurely, which c...

CVE-2023-53071

CVE-2023-53071 affects the Linux kernel WiFi driver mt76. The root cause was calling ieee80211_unregister_hw unconditionally when probing a mt7921e PCI card without firmware, which could lead to a NULL pointer dereference on driver removal. The fix ensures mt76_unregister_device is invoked only f...

CVE-2023-53071 wifi: mt76: do not run mt76_unregister_device() on unregistered hw

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: do not run mt76unregisterdevice on unregistered hw Trying to probe a mt7921e pci card without firmware results in a successful probe where ieee80211registerhw hasn't been called. When removing the driver,...
