kernel: nvme-tcp: fix potential memory corruption in nvme_tcp_recv_pdu()

An unchecked buffer bounds flaw was found in the Linux kernel's NVMe TCP Fabrics driver. An attacker with the ability to send a crafted packet to an affected NVMe host could exploit this flaw to alter kernel memory, leading to an escalation of privileges or a compromise of system integrity or...

QEMU: virtio-net: stack buffer overflow in virtio_net_flush_tx()

A stack based buffer overflow was found in the virtio-net device of QEMU. This issue occurs when flushing TX in the virtionetflushtx function if guest features VIRTIONETFHASHREPORT, VIRTIOFVERSION1 and VIRTIONETFMRGRXBUF are enabled. This could allow a malicious user to overwrite local variables...

The vulnerability of the sev_receive_start() function in the arch/x86/kvm/svm/sev.c module of the virtualization subsystem on the x86 kernel of the Linux operating system allows a attacker to compromise the integrity and accessibility of the protected information.

The vulnerability of the sevreceivestart function in the arch/x86/kvm/svm/sev.c module of the virtualization subsystem on the Linux kernel-based x86 platform is related to the failure to release resources after their useful life has ended. Exploiting this vulnerability could allow an attacker to...
