In the Linux kernel, the following vulnerability has been resolved:
cfi: Fix __cfi_slowpath_diag RCU usage with cpuidle
RCU_NONIDLE usage during __cfi_slowpath_diag can result in an invalid
RCU state in the cpuidle code path:
WARNING: CPU: 1 PID: 0 at kernel/rcu/tree.c:613 rcu_eqs_enter+0xe4/0x138
...
Call trace:
rcu_eqs_enter+0xe4/0x138
rcu_idle_enter+0xa8/0x100
cpuidle_enter_state+0x154/0x3a8
cpuidle_enter+0x3c/0x58
do_idle.llvm.6590768638138871020+0x1f4/0x2ec
cpu_startup_entry+0x28/0x2c
secondary_start_kernel+0x1b8/0x220
__secondary_switched+0x94/0x98
Instead, call rcu_irq_enter/exit to wake up RCU only when needed and
disable interrupts for the entire CFI shadow/module check when we do.Verknüpft mit AI von unstrukturierten Daten zu bestehenden CPE der NVD
