CVE-2023-53070

CVE-2023-53070 affects the Linux kernel: when PPTT is absent, multiple CPUs could call acpi_get_pptt() in atomic context, risking a sleep waiting on a mutex and a kernel crash trace. The fix updates acpi_get_pptt() to return NULL if PPTT is not available, avoiding sleeps in atomic context and pre...
