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

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 s390/uv: Prevent potential out-of-bounds read

In the Linux kernel, the following vulnerability has been resolved: s390/uv: Prevent potential out-of-bounds read When the system has more than 85 secrets, the uvsecretlist struct array only holds up to 85 items per page, resulting in an out of bounds read in findsecretinpage if the targeted secr...

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...

CVE-2026-98646

The Linux kernel contains a vulnerability where bpf_sock_destroy() runs from the tcp iterator under rcu_read_lock() . If a socket is a listener with children in its accept queue, tcp_abort() triggers inet_csk_listen_stop(). The cond_resched() call within that path trips a debug check because it a...

CVE-2026-98645

The Linux kernel contains a use-after-free and double free vulnerability in the HID: winwing driver. The issue occurs because winwing_init_ff() passes private data allocated via devm_kzalloc() to input_ff_create_memless(), which then incorrectly frees the pointer using kfree() during teardown. Th...
