Xen Hypervisor Memory Leak on Boot (XSA-235)

According to its self-reported version number, the Xen hypervisor installed on the remote host is affected by flaw within the pagealloc.c and asm-arm/numa.h due to not scrubbing the memory on boot. This could potentially leave sensitive information available to read after a reboot. This issue onl...

the linux kernel recursive vulnerability--translated from P0 of the article-vulnerability warning-the black bar safety net

Linux gives each user process is assigned a 8M the size of the stack, if the program runs out of this stack, such as with the infinite recursion, it will trigger the stack to the back of the page protection. But the Linux kernel stack is very different, especially in the processing of the system...
