SUSE CVE-2020-27675

An issue was discovered in the Linux kernel through 5.9.1, as used with Xen through 4.14.x. drivers/xen/events/eventsbase.c allows event-channel removal during the event-handling loop a race condition. This can cause a use-after-free or NULL pointer dereference, as demonstrated by a dom0 crash vi...

SUSE CVE-2021-28039

An issue was discovered in the Linux kernel 5.9.x through 5.11.3, as used with Xen. In some less-common configurations, an x86 PV guest OS user can crash a Dom0 or driver domain via a large amount of I/O activity. The issue relates to misuse of guest physical addresses when a configuration has...

An issue was discovered in the Linux kernel through 5.10.1 as used with Xen through 4.14.x. The Linux kernel PV block backend expects the kernel thread handler to reset ring->xenblkd to NULL when stopped. However the handler may not have time to run if the frontend quickly toggles between the states connect and disconnect. As a consequence the block backend may re-use a pointer after it was freed. A misbehaving guest can trigger a dom0 crash by continuously connecting / disconnecting a block frontend. Privilege escalation and information leaks cannot be ruled out. This only affects systems with a Linux blkback.
