CVE-2026-45968

The CVE-2026-45968 issue is in the Linux kernel cpuidle: when only a single idle state is available (e.g., certain PowerNV platforms), the ladder governor can select an out-of-bounds state. The fix adds a bail-out in cpuidle_select() to return state 0 directly when state_count <= 1, bypassing ...

CVE-2026-45968

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 sta...
