{"id":"DEBIAN-CVE-2022-50012","details":"In the Linux kernel, the following vulnerability has been resolved:  powerpc/64: Init jump labels before parse_early_param()  On 64-bit, calling jump_label_init() in setup_feature_keys() is too late because static keys may be used in subroutines of parse_early_param() which is again subroutine of early_init_devtree().  For example booting with \"threadirqs\":    static_key_enable_cpuslocked(): static key '0xc000000002953260' used before call to jump_label_init()   WARNING: CPU: 0 PID: 0 at kernel/jump_label.c:166 static_key_enable_cpuslocked+0xfc/0x120   ...
