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...

CVE-2022-49395

CVE-2022-49395 concerns the Linux kernel, where an out-of-bounds read occurs in LDT setup due to syscall_stub_data() treating data_count as bytes instead of longs. This yields a 128-byte read on the stack (local to swapper/1) and is triggered during LDT entry initialization. Public advisories fro...
