QEMU: net: e1000e: use-after-free while sending packets

A use-after-free flaw was found in the INTEL 82574 NIC e1000e emulator of the QEMU. The issue happens while sending packets if the guest user has set the packet data address to the e1000e's MMIO address. This flaw allows a guest user or process to crash the QEMU process on the host, resulting in ...

QEMU: reachable assertion failure in net_tx_pkt_add_raw_fragment() in hw/net/net_tx_pkt.c

An assertion failure flaw was found in QEMU in the network packet processing component. This issue affects the "e1000e" and "vmxnet3" network devices. This flaw allows a malicious guest user or process to abort the QEMU process on the host, resulting in a denial of service...

QEMU: infinite loop in e1000e_write_packet_to_guest() in hw/net/e1000e_core.c

An infinite loop flaw was found in the e1000e NIC emulation code of QEMU. This issue occurs in the e1000ewritepackettoguest routine while processing bogus RX descriptor data transmitted by the guest. This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a...

QEMU: e1000e: infinite loop scenario in case of null packet descriptor

An infinite loop flaw was found in the e1000e device emulator in QEMU. This issue could occur while receiving packets via the e1000ewritepackettoguest routine, if the receiveRX descriptor has a NULL buffer address. This flaw allows a privileged guest user to cause a denial of service. The highest...
