CVE-2026-98652

The Linux kernel contains a vulnerability in the KVM subsystem specifically affecting the s390 architecture. The issue is caused by a missing srcu (or slots lock) in the kvm_s390_set_irq_state() function during the Store status operation, similar to the requirement in kvm_s390_inject_vcpu(). The ...

EUVD-2026-103565

In the Linux kernel, the following vulnerability has been resolved: KVM: s390: Properly handle NULL pointer in datcondsetstoragekey Some callers pass NULL as oldkey. Calling pagecondsetstoragekey will cause that NULL pointer to get dereferenced. Fix by checking for NULL and assigning the pointer ...

EUVD-2026-103564

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...

CVE-2026-98649 KVM: s390: Fix race in _destroy_pages_crste()

In the Linux kernel, the following vulnerability has been resolved: KVM: s390: Fix race in destroypagescrste Use READONCE in destroypagescrste to read the crste, avoid dereferencing the pointer multiple times...

CVE-2026-98649

The Linux kernel contains a race condition within the KVM s390 module in the _destroy_pages_crste() function. The underlying cause is the multiple dereferencing of a pointer, which can be mitigated by using READ_ONCE() to read the crste. No specific version numbers, impact details, or exploit inf...

CVE-2026-98648

The Linux kernel contains an out-of-bounds read vulnerability in the s390/uv component. The issue occurs when the system contains more than 85 secrets, as the uv_secret_list struct array only holds up to 85 items per page. This causes an out-of-bounds read in the find_secret_in_page function if t...

CVE-2026-98647

The Linux kernel contains a divide-by-zero vulnerability in the btf_struct_walk() function. The issue occurs when a BPF program access goes past a structure where the last member is a flexible array ; the function fails to verify that the element type has a non-zero size before performing a modul...
