https://notcve.org/view.php?id=CVE-2022-49932
02 May 2025 — In the Linux kernel, the following vulnerability has been resolved: KVM: VMX: Do _all_ initialization before exposing /dev/kvm to userspace Call kvm_init() only after _all_ setup is complete, as kvm_init() exposes /dev/kvm to userspace and thus allows userspace to create VMs (and call other ioctls). E.g. KVM will encounter a NULL pointer when attempting to add a vCPU to the per-CPU loaded_vmcss_on_cpu list if userspace is able to create a VM before vmx_init() configures said list.

02 May 2025 — In the Linux kernel, the following vulnerability has been resolved: net_sched: hfsc: Fix a UAF vulnerability in class handling This patch fixes a Use-After-Free vulnerability in the HFSC qdisc class handling. The issue occurs due to a time-of-check/time-of-use condition in hfsc_change_class() when working with certain child qdiscs like netem or codel. The vulnerability works as follows: 1. hfsc_change_class() checks if a class has packets (q.qlen != 0) 2. It then calls qdisc_peek_len(), which for certain qd... • https://git.kernel.org/stable/c/21f4d5cc25ec0e6e8eb8420dd2c399e6d2fc7d14 •

Indeed another concurrent vif schedule_and_wake_txq call could cause those packets to be dequeued (see ieee80211_handle_wake_tx_queue()) without checking the sdata current state. Because vif.drv_priv is now cleared in this function, this could lead to driver crash.
