Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from the failure to protect dstdev access with an RCU, which could lead to reuse after release...

The vulnerability of the rcu_preempt_deferred_qs_handler() function in the kernel/rcu/tree_plugin.h file of the Linux operating system allows a attacker to trigger a service failure.

The vulnerability of the rcupreemptdeferredqshandler function in the kernel/rcu/treeplugin.h header file of the Linux operating system is related to the simultaneous execution using shared resources with incorrect synchronization. Exploiting this vulnerability allows an attacker to trigger a...
