CVE-2021-47553 sched/scs: Reset task stack state in bringup_cpu()

In the Linux kernel, the following vulnerability has been resolved: sched/scs: Reset task stack state in bringupcpu To hot unplug a CPU, the idle task on that CPU calls a few layers of C code before finally leaving the kernel. When KASAN is in use, poisoned shadow is left around for each of the...

CVE-2021-47553

The CVE describes a Linux kernel issue (CVE-2021-47553) in the SCS and KASAN shadow stack handling for the idle task during CPU hotplug (bringup_cpu). When a CPU is offline and brought back online, stale KASAN shadow and stale shadow call stack (SCS) state could lead to bogus warnings or leak por...
