Races in the grant table unmap code

ISSUE DESCRIPTION We have discovered two bugs in the code unmapping grant references. When a grant had been mapped twice by a backend domain, and then unmapped by two concurrent unmap calls, the frontend may be informed that the page had no further mappings when the first call completed rather th...

Kernel: mm: try_to_unmap_cluster() should lock_page() before mlocking

It was found that the trytounmapcluster function in the Linux kernel's Memory Managment subsystem did not properly handle page locking in certain cases, which could potentially trigger the BUGON macro in the mlockvmapage function. A local, unprivileged user could use this flaw to crash the system...

security flaw

The ELF loader in Linux kernel 2.4 before 2.4.25 allows local users to cause a denial of service crash via a crafted ELF file with an interpreter with an invalid arch architecture, which triggers a BUG when an invalid VMA is unmapped...
