LSN-120-1: Kernel Live Patch Security Notice

In the Linux kernel, the following vulnerability has been
resolved: KVM: arm64: Tear down vGIC on failed vCPU creation If
kvm_arch_vcpu_create() fails to share the vCPU page with the hypervisor, we
propagate the error back to the ioctl but leave the vGIC vCPU data
initialised.

In the Linux kernel, the following vulnerability has been
resolved: nvmet-tcp: add bounds checks in nvmet_tcp_build_pdu_iovec
nvmet_tcp_build_pdu_iovec() could walk past cmd->req.sg when a PDU length
or offset exceeds sg_cnt and then use bogus sg->length/offset values,
leading to _copy_to_iter() GPF/KASAN.

It was discovered that the Linux kernel algif_aead module did not properly
handle in-place cryptographic operations. This flaw is known as Copy Fail.
A local attacker could use this to escalate privileges, or possibly escape
a container.)(CVE-2026-31431)
