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 use of a mutex lock to protect a context list in a hard IRQ context, which could result in a scheduler...

CVE-2022-49090

The CVE-2022-49090 entry concerns Linux kernel arch/arm64: Fix topology initialization for core scheduling. The issue arises when store_cpu_topology() does not call update_siblings_masks() before notify_cpu_starting(), causing core scheduling data structures to reflect an incorrect topology. If s...
