CVE-2026-74610

CVE-2026-74610 is a kernel NULL pointer dereference in the Linux kernel's TLS ULP (Upper Layer Protocol) implementation. The root cause is in tls_sw_sendmsg_locked(): when the copy path fills the plaintext sk_msg ring, the full_record flag is not set, leaving the record unpushed. A subsequent spl...

CVE-2026-74607 KVM: SVM: Serialize accesses to the owner and mirror list with separate lock

In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Serialize accesses to the owner and mirror list with separate lock Interaction between KVMCAPVMMOVEENCCONTEXTFROM and KVMCAPVMCOPYENCCONTEXTFROM can cause two separate issues: - in sevmigratefrom, when the destination K...

CVE-2026-74607

A race condition in the Linux kernel's KVM SVM (Secure Virtual Machine) module affects the management of encrypted VM owner and mirror lists. When KVM_CAP_VM_MOVE_ENC_CONTEXT_FROM and KVM_CAP_VM_COPY_ENC_CONTEXT_FROM interact concurrently, sev_migrate_from() can corrupt the owner's mirror list by...

CVE-2026-74606

CVE-2026-74606 is a use-after-free vulnerability in the Linux kernel's eventfs component, specifically in eventfs_remove_rec(). When this function recursively removes a child entry, it subsequently reads list.next from that child via list_for_each_entry(). If free_ei() drops the final reference a...
