UBUNTU-CVE-2023-0597
A flaw possibility of memory leak in the Linux kernel cpu_entry_area mapping of X86 CPU data to memory was found in the way user can guess location of exception stack(s) or other important data. A local user could use this flaw to get access to some important data with expected location in memory.
