CVE-2026-98653 KVM: s390: Fix _gaccess_shadow_fault()

In the Linux kernel, the following vulnerability has been resolved: KVM: s390: Fix gaccessshadowfault In some circumstances, it is possible that the page of nested guest memory that is being shadowed is not present at all in the parent guest gmap. datentrywalk will not find any leaf entry and...

CVE-2026-98653

The Linux kernel contains a vulnerability within the KVM s390 subsystem. Specifically, in certain circumstances, a page of nested guest memory being shadowed may be missing from the parent guest gmap . This causes dat_entry_walk() to fail to find a leaf entry and return -ENOENT , which is then er...

CVE-2026-98650

The Linux kernel contains a vulnerability in the KVM: s390 component due to potential races in dat skey functions . Specifically, a race window exists between dat_entry_walk() and large_crste_to_phys() where a large page could be split concurrently. This can cause large_crste_to_phys() to be call...

CVE-2026-98650 KVM: s390: Fix potential races in dat skey functions

In the Linux kernel, the following vulnerability has been resolved: KVM: s390: Fix potential races in dat skey functions When datcondsetstoragekey finds a large page, it will conditionally set the storage key in absolute memory using largecrstetophys to get the absolute address. There is a race...
