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 HID: winwing: fix use-after-free in force feedback teardown

In the Linux kernel, the following vulnerability has been resolved: HID: winwing: fix use-after-free in force feedback teardown winwinginitff passes the driver's private data, allocated with devmkzalloc in winwingprobe, as the effect context to inputffcreatememless. The memoryless force-feedback...

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 bpf: Avoid soft lockup in __htab_map_lookup_and_delete_batch()

In the Linux kernel, the following vulnerability has been resolved: bpf: Avoid soft lockup in htabmaplookupanddeletebatch htabmaplookupanddeletebatch has no rescheduling point. The batch count bounds how many entries are copied out, not how many buckets are visited, so one BPFMAPLOOKUPBATCH call...

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...

CVE-2026-98643

The Linux kernel is vulnerable to an out-of-bounds read within the bpf subsystem. Specifically, a sockops program reading skops->rtt_min fails to verify the socket type. On the tcp_conn_request() path, sock_ops->sk is a request_sock (non-full), but the context rewrite incorrectly casts it t...
