Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: cpuidle: Skip the 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 stat...

CVE-2026-45968

A flaw was found in the Linux kernel's cpuidle subsystem. On certain PowerNV systems, when only a single idle state is available, the cpuidle ladder governor may incorrectly treat state 1 as usable. This can lead to an out-of-bounds index being passed, causing a NULL enter callback to be invoked...

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 ...
