  "details": "In the Linux kernel, the following vulnerability has been resolved:  cpuidle: Skip governor when only one idle state is available  On certain platforms (PowerNV systems without a power-mgt DT node), cpuidle may register only a single idle state. In cases where that single state is a polling state (state 0), the ladder governor may incorrectly treat state 1 as the first usable state and pass an out-of-bounds index. This can lead to a NULL enter callback being invoked, ultimately resulting in a system crash.  [   13.342636] cpuidle-powernv : Only Snooze is available [   13.351854] Faulting instruction address: 0x00000000 [   13.376489] NIP [0000000000000000] 0x0 [   13.378351] LR  [c000000001e01974] cpuidle_enter_state+0x2c4/0x668  Fix this by adding a bail-out in cpuidle_select() that returns state 0 directly when state_count \u003c= 1, bypassing the governor and keeping the tick running.",
