kernel: wifi: mac80211: drop stray 'static' from fast-RX rx_result

A flaw was found in the Linux kernel's Wi-Fi mac80211 subsystem. The ieee80211invokefastrx function uses a static variable for rxresult, which is shared across concurrent calls. This can lead to incorrect processing of Wi-Fi packets, where a packet might be mishandled or its status incorrectly...

kernel: Bluetooth: hci_event: Fix UAF in hci_acl_create_conn_sync

A flaw was found in the Linux kernel’s Bluetooth subsystem HCI. Specifically, in the function hciaclcreateconnsync and related path hcilecreateconnsync, a connection object in state BTOPEN that is still pending command submission may be freed prematurely, leading to a use-after-free condition. An...

USN-8575-2: Linux kernel vulnerabilities

Maxim Suhanov discovered that the NTFS file system implementation in the Linux kernel did not properly validate file name length in certain situations, leading to an out-of-bounds read. An attacker could use this to construct a malicious NTFS image that, when mounted and operated on, could expose...
