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...

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix divide-by-zero in btfstructwalk When an access goes past the struct and the last member is a flexible array, btfstructwalk folds the offset back into a single element with off - moff % t-size, but never checks that the...

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 tcp: Skip cond_resched() in inet_csk_listen_stop() under BPF context

In the Linux kernel, the following vulnerability has been resolved: tcp: Skip condresched in inetcsklistenstop under BPF context bpfsockdestroy runs from the tcp iterator, under rcureadlock. If the sock is a listener that still has children in its accept queue, tcpabort ends up in inetcsklistenst...

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...

CVE-2026-98644

The Linux kernel contains a vulnerability in the BPF subsystem within the __htab_map_lookup_and_delete_batch() function. The root cause is a lack of rescheduling points; a single BPF_MAP_LOOKUP_BATCH call can traverse a large hash map end-to-end, especially during consecutive empty bucket travers...
