CVE-2023-3640

A possible unauthorized memory access flaw was found in the Linux kernel's cpuentryarea mapping of X86 CPU data to memory, where a user may guess the location of exception stacks or other important data. Based on the previous CVE-2023-0597, the 'Randomize per-cpu entry area' feature was implement...

CVE-2023-3640

CVE-2023-3640 – summary (Linux kernel x86 per-CPU entry area leak) A local memory leakage flaw was identified in the Linux kernel’s cpu_entry_area mapping for X86, enabling a local user to infer addresses of exception stacks and other kernel data. The vulnerability stems from partial randomness o...
