kernel: um: Fix out-of-bounds read in LDT setup

A vulnerability was found in the Linux kernel's user mode um subsystem, specifically within the Local Descriptor Table LDT setup functionality. The issue arises from the syscallstubdata function misinterpreting the datacount parameter as a byte count rather than a count of longs, leading to an...
