CVE-2026-74522

In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix use-after-free in closefiletableids A ksmbdfile can remain alive after logical close while another session holds a temporary reference obtained through ksmbdlookupfdinode. ksmbdclosefd currently marks the file closed a...

CVE-2026-74516

The CVE-2026-74516 issue affects the Linux kernel (KVM/SMV) where, if AVIC is inhibited while L2 is active, the host may run L1 with AVIC disabled and with x2APIC MSR intercepts also disabled. This allows L1 to access the host APIC state, trigger arbitrary interrupts, modify task priority, and co...
