Linux kernel security vulnerabilities

Linux kernel is the kernel used by the Linux Foundation's open source operating system Linux. A security vulnerability exists in the Linux kernel that stems from the use of spinlock instead of rawspinlock by the dropmonitor component. spinlock uses a sleep lock, which can cause problems in...
