CVE-2026-98465 RISC-V: KVM: Serialize IMSIC attributes with vCPU migration

In the Linux kernel, the following vulnerability has been resolved: RISC-V: KVM: Serialize IMSIC attributes with vCPU migration KVM device ioctls are not serialized against KVMRUN. As a result, kvmriscvaiaimsicrwattr can snapshot the physical CPU and HGEI of an IMSIC VS-file before a concurrent...

CVE-2026-98465

The Linux kernel contains a vulnerability in the RISC-V KVM implementation where KVM device ioctls are not serialized against KVM_RUN . This allows kvm_riscv_aia_imsic_rw_attr() to snapshot the physical CPU and HGEI of an IMSIC VS-file before a concurrent vCPU migration releases it. Consequently,...

CVE-2026-98464

The Linux kernel contains a race condition in the RISC-V KVM implementation where a non-Sstc hrtimer callback clears next_set before its final use of the enclosing vCPU . If teardown occurs simultaneously, kvm_riscv_vcpu_timer_cancel() may skip hrtimer_cancel(), allowing kvm_destroy_vcpus() to fr...

CVE-2026-98463 sched_ext: Derive SCX_RQ_IN_WAKEUP from the core enqueue flags

In the Linux kernel, the following vulnerability has been resolved: schedext: Derive SCXRQINWAKEUP from the core enqueue flags scheduledeferredlocked skips scheduling a deferred action while SCXRQINWAKEUP is set and relies on the taskwokenscx call that follows a wakeup enqueue to run it...

CVE-2026-98463

The Linux kernel contains a vulnerability within the sched_ext framework where SCX_RQ_IN_WAKEUP is incorrectly derived from merged enqueue flags. Specifically, move_remote_task_to_local_dsq() sets this flag without a subsequent task_woken_scx() call, causing deferred actions to remain pending. Th...

CVE-2026-98462

The Linux kernel Bluetooth stack contains a flaw in how CIS hold ownership is handled during reuse. Specifically, the functions hci_bind_cis() and hci_connect_cis() may fail to correctly manage ISO layer holds. In hci_bind_cis(), holds are currently taken only after CIS configuration, leading to ...
