Arm guests can cause Dom0 DoS via PV devices When mapping pages of guests on Arm dom0 is using an rbtree to keep track of the foreign mappings. Updating of that rbtree is not always done completely with the related lock held resulting in a small race window which can be used by unprivileged guests via PV devices to cause inconsistencies of the rbtree. These inconsistencies can lead to Denial of Service (DoS) of dom0 e.g. by causing crashes or the inability to perform further mappings of other guests' memory pages.

CVE-2021-36710

ToaruOS 1.99.2 is affected by incorrect access control via the kernel. Improper MMU management and having a low GDT address allows it to be mapped in userland. A call gate can then be written to escalate to CPL 0...

CVE-2021-26368

CVE-2021-26368 is an AMD firmware/Trusted OS issue where insufficient process-type checking can allow a less-privileged process to unmap memory owned by a higher-privileged process, causing denial of service. The AMD advisory (AMD-SB-1027) and related CVE table map this to multiple AMD Ryzen plat...

kernel: possible leak or coruption of data residing on hugetlbfs

A memory leak flaw in the Linux kernel's hugetlbfs memory usage was found in the way the user maps some regions of memory twice using shmget which are aligned to PUD alignment with the fault of some of the memory pages. A local user could use this flaw to get unauthorized access to some data...
