CVE-2025-37778

CVE-2025-37778 is a Linux kernel vulnerability in ksmbd’s krb_authenticate path. The root cause is a use-after-free: krb_authenticate frees sess->user and may not NULL it; if ksmbd_krb5_authenticate does not reinitialize sess->user, smb2_sess_setup may later access freed memory. Several adv...

CVE-2025-37778 ksmbd: Fix dangling pointer in krb_authenticate

In the Linux kernel, the following vulnerability has been resolved: ksmbd: Fix dangling pointer in krbauthenticate krbauthenticate frees sess-user and does not set the pointer to NULL. It calls ksmbdkrb5authenticate to reinitialise sess-user but that function may return without doing so. If that...

CVE-2025-23141 KVM: x86: Acquire SRCU in KVM_GET_MP_STATE to protect guest memory accesses

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Acquire SRCU in KVMGETMPSTATE to protect guest memory accesses Acquire a lock on kvm-srcu when userspace is getting MP state to handle a rather extreme edge case where "accepting" APIC events, i.e. processing pending IN...

CVE-2025-23141

CVE-2025-23141: In the Linux kernel KVM x86, acquiring the SRCU lock when retrieving MP state (KVM_GET_MP_STATE) can trigger a nested VM-Exit and potentially access guest memory in edge cases (e.g., L2 with INIT and pending TRIPLE_FAULT). The issue arises when the vCPU handling of MP state intera...
