CVE-2023-0597 affects the Linux kernel on x86 systems before Linux 6.2. The per-CPU cpu_entry_area, which includes sensitive entry-related kernel data such as exception stacks and transition-state data, was mapped at a fixed, predictable kernel virtual-address location. A local attacker could use user-influenced data placed through the privilege-transition stack and saved register context at a predictable kernel-space address. This predictability can disclose or facilitate access to sensitive data and can aid construction of fake kernel structures or kernel ROP chains. Linux 6.2 introduced per-CPU entry-area offset randomization relative to the IDT when KASLR is enabled.
