This update is based on the upstream 5.6.8 kernel and fixes at least the following security issues:
usbsgcancel in drivers/usb/core/message.c in the Linux kernel before 5.6.8 has a use-after-free because a transfer occurs without a reference(CVE-2020-12464).
An issue was discovered in the Linux kernel before 5.6.7. xdpumemreg in net/xdp/xdpumem.c has an out-of-bounds write (by a user with the CAPNET_ADMIN capability) because of a lack of headroom validation (CVE-2020-12659).
Other fixes in this update: - printk: queue wakeupklogd irqwork only if per-CPU areas are ready - Fix use after free in gettreebdev() - propagateone(): mntsetmountpoint() needs mount_lock - iwlwifi: pcie: handle QuZ configs with killer NICs as well - Fix building out of tree modules on aarch64 (pterjan)
