kernel security update
The Linux Kernel, the operating system core itself.
Security Fix(es):
A flaw in the Linux Kernel found. Fail if no bound addresses can be used for a given scope. A type confusion can happen in inet_diag_msg_sctpasoc_fill() in net/sctp/diag.c, which uses a type confused pointer to return information to userspace when issuing a list_entry() on asoc->base.bind_addr.address_list.next when the list is empty.

A flaw was found in the Linux kernel. A use-after-free may be triggered in asus_kbd_backlight_set when plugging/disconnecting in a malicious USB device, which advertises itself as an Asus device.
Similarly to the previous known CVE-2023-25012, but in asus devices, the work_struct may be scheduled by the LED controller while the device is disconnecting, triggering a use-after-free on the struct asus_kbd_leds *led structure. A malicious USB device may exploit the issue to cause memory corruption with controlled data.

A flaw found in the Linux Kernel. The missing check causes a type confusion when issuing a list_entry()
on an empty report_list. The problem is caused by the assumption that the device must have valid report_list. While this will be true for all normal HID devices, a suitably malicious device can violate the assumption.
