kernel: xen/privcmd: fix double free via VMA splitting
A flaw was found in the Linux kernel's xen/privcmd module. A local user could exploit this by performing a partial unmapping of a privcmd memory region. This action causes a Virtual Memory Area VMA to split, leading to duplicated internal memory pointers. As a result, the same memory can be freed...
kernel: wifi: mac80211: remove station if connection prep fails
A flaw was found in the Linux kernel's mac80211 Wi-Fi subsystem. When Multi-Link Operation MLO connection preparation fails, the system may not correctly remove the associated station. This can lead to a use-after-free or double-free vulnerability in the debugfs component, potentially causing...
kernel: exit: prevent preemption of oopsing TASK_DEAD task
