CVE-2026-98861

The Linux kernel contains a vulnerability in the fprobe mechanism used by BPF kprobe-multi . The issue arises because unregister_fprobe() and unregister_fprobe_async() rely on standard RCU grace periods (synchronize_rcu() and call_rcu()) to wait for in-flight handlers. If a handler executes while...

CVE-2026-98860 HID: bpf: cast size to ssize_t when checking hid_bpf_hw_request

In the Linux kernel, the following vulnerability has been resolved: HID: bpf: cast size to ssizet when checking hidbpfhwrequest As reported by Sashiko: If a transport driver encounters a hardware error and returns a negative error code such as -EPIPE, ret is implicitly promoted to sizet when...

CVE-2026-98860

The Linux kernel contains a vulnerability in the HID BPF subsystem related to how hid_bpf_hw_request handles hardware errors. When a transport driver returns a negative error code (e.g., -EPIPE ), the return value is implicitly promoted to size_t, causing a comparison against size to evaluate as ...

CVE-2026-98859

The Linux kernel contains a vulnerability in the HID multitouch subsystem where the mt_remove() function fails to properly prevent the sticky-finger timer from being rearmed during hardware removal. While timer_delete_sync() is used to quiesce the timer, it does not prevent the transport layer fr...

CVE-2026-98858

The Linux kernel contains a use-after-free vulnerability within the io_uring subsystem involving SQPOLL . The issue occurs because the sqpoll thread processes task_work off its own list, allowing io_ring_exit_work() to free the context (ctx) and tctx while io_req_normal_work_add() is still access...
