In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Ignore -EBUSY when checking nested events from vcpu_block() Ignore -EBUSY when checking nested events after exiting a blocking state while L2 is active, as exiting to userspace will generate a spurious userspace exit, usually with KVM_EXIT_UNKNOWN, and likely lead to the VM's demise. Continuing with the wakeup isn't perfect either, as *something* has gone sideways if a vCPU is awakened in L2 with an injected event (or worse, a nested run pending), but continuing on gives the VM a decent chance of surviving without any major side effects. As explained in the Fixes commits, it _should_ be impossible for a vCPU to be put into a blocking state with an already-injected event (exception, IRQ, or NMI). Unfortunately, userspace can stuff MP_STATE and/or injected events, and thus put the vCPU into what should be an impossible state. Don't bother trying to preserve the WARN, e.g. with an anti-syzkaller Kconfig, as WARNs can (hopefully) be added in paths where _KVM_ would be violating x86 architecture, e.g. by WARNing if KVM attempts to inject an exception or interrupt while the vCPU isn't running.

An update of the linux package has been released.

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - KVM: x86: Ignore -EBUSY when checking nested events from vcpu_block() Ignore -EBUSY when checking nested     events after exiting a blocking state while L2 is active, as exiting to userspace will generate a spurious     userspace exit, usually with KVM_EXIT_UNKNOWN, and likely lead to the VM's demise. Continuing with the     wakeup isn't perfect either, as *something* has gone sideways if a vCPU is awakened in L2 with an injected     event (or worse, a nested run pending), but continuing on gives the VM a decent chance of surviving     without any major side effects. As explained in the Fixes commits, it _should_ be impossible for a vCPU to     be put into a blocking state with an already-injected event (exception, IRQ, or NMI). Unfortunately,     userspace can stuff MP_STATE and/or injected events, and thus put the vCPU into what should be an     impossible state. Don't bother trying to preserve the WARN, e.g. with an anti-syzkaller Kconfig, as WARNs     can (hopefully) be added in paths where _KVM_ would be violating x86 architecture, e.g. by WARNing if KVM     attempts to inject an exception or interrupt while the vCPU isn't running. (CVE-2026-43265)

Note that Nessus relies on the presence of the package as reported by the vendor.
