CVE-2022-23087

The CVE-2022-23087 issue affects the e1000 device emulation in bhyve on FreeBSD, where the device model uses an on‑stack buffer to modify transmitted packets. When checksum offload is requested, a guest‑provided checksum offset is accepted without validation for certain packet types, enabling a m...

CVE-2022-23087 Bhyve e82545 device emulation out-of-bounds write

The e1000 network adapters permit a variety of modifications to an Ethernet packet when it is being transmitted. These include the insertion of IP and TCP checksums, insertion of an Ethernet VLAN header, and TCP segmentation offload "TSO". The e1000 device model uses an on-stack buffer to generat...

Low: qemu

Issue Overview: An infinite loop flaw was found in the e1000 NIC emulator of the QEMU. This issue occurs while processing transmits tx descriptors in processtxdesc if various descriptor fields are initialized with invalid values. This flaw allows a guest to consume CPU cycles on the host, resulti...

An infinite loop flaw was found in the e1000 NIC emulator of the QEMU. This issue occurs while processing transmits (tx) descriptors in process_tx_desc if various descriptor fields are initialized with invalid values. This flaw allows a guest to consume CPU cycles on the host resulting in a denial of service. The highest threat from this vulnerability is to system availability.

SUSE CVE-2004-0535

The e1000 driver for Linux kernel 2.4.26 and earlier does not properly initialize memory before using it, which allows local users to read portions of kernel memory. NOTE: this issue was originally incorrectly reported as a "buffer overflow" by some sources...

SUSE CVE-2009-1385

Integer underflow in the e1000cleanrxirq function in drivers/net/e1000/e1000main.c in the e1000 driver in the Linux kernel before 2.6.30-rc8, the e1000e driver in the Linux kernel, and Intel Wired Ethernet aka e1000 before 7.5.5 allows remote attackers to cause a denial of service panic via a...

SUSE CVE-2009-4536

drivers/net/e1000/e1000main.c in the e1000 driver in the Linux kernel 2.6.32.3 and earlier handles Ethernet frames that exceed the MTU by processing certain trailing payload data as if it were a complete frame, which allows remote attackers to bypass packet filters via a large packet with a craft...

SUSE CVE-2012-0029

Heap-based buffer overflow in the processtxdesc function in the e1000 emulation hw/e1000.c in qemu-kvm 0.12, and possibly other versions, allows guest OS users to cause a denial of service QEMU crash and possibly execute arbitrary code via crafted legacy mode packets...

SUSE CVE-2012-6075

Buffer overflow in the e1000receive function in the e1000 device driver hw/e1000.c in QEMU 1.3.0-rc2 and other versions, when the SBP and LPE flags are disabled, allows remote attackers to cause a denial of service guest OS crash and possibly execute arbitrary guest code via a large packet...

SUSE CVE-2015-6815

The processtxdesc function in hw/net/e1000.c in QEMU before 2.4.0.1 does not properly process transmit descriptor data when sending a network packet, which allows attackers to cause a denial of service infinite loop and guest crash via unspecified vectors...
