CVE-2026-79603

x86 PV guests can free memory pages while still keeping a stale TLB entry pointing to them. A TLB flush is only issued by Xen if needed when the page is re-used. Since it's possible for the page to be scrubbed ahead of the TLB flush, there's a window where a PV guest can modify an already scrubbe...

CVE-2026-79603

Xen hypervisor x86 PV (para-virtualized) guests can free memory pages while retaining a stale TLB entry pointing to them. Xen issues a TLB flush only when a freed page is re-used , not at the time of freeing. Because the page can be scrubbed (zeroed or reassigned) before that TLB flush occurs, a ...

kernel: unmap_mapping_range() race with munmap() on VM_PFNMAP mappings leads to stale TLB entry

A flaw was found in include/asm-generic/tlb.h in the Linux kernel due to a race condition unmapmappingrange versus munmap. This issue allows a device driver to free a page while it still has stale TLB entries...

SUSE CVE-2018-18281

Since Linux kernel version 3.2, the mremap syscall performs TLB flushes after dropping pagetable locks. If a syscall such as ftruncate removes entries from the pagetables of a task that is in the middle of mremap, a stale TLB entry can remain for a short time that permits access to a physical pag...
