CVE-2024-46797 powerpc/qspinlock: Fix deadlock in MCS queue
In the Linux kernel, the following vulnerability has been resolved: powerpc/qspinlock: Fix deadlock in MCS queue If an interrupt occurs in queuedspinlockslowpath after we increment qnodesp-count and before node-lock is initialized, another CPU might see stale lock values in gettailqnode. If the...
CVE-2024-46797
CVE-2024-46797 : In the Linux kernel (PowerPC/MCS qspinlock), a deadlock can occur when an interrupt happens in queued_spin_lock_slowpath() after qnodesp->count is incremented but before node->lock is initialized. This can allow a CPU to see stale lock values and write the wrong qnode’s nex...
