CVE-2021-28715

CVE-2021-28715 concerns the Linux kernel netback driver in Xen guests. The Xen netback path buffers incoming guest data until the guest processes it, and although there are safeguards to limit buffering, an attacker running in a guest can bypass them. Specifically, when using UDP on a fast interf...

Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 5.17-rc1 Description: The issue is related to an information leak flaw in the Linux kernel's TIPC protocol subsystem. This flaw occurs due to uninitialized memory when a user sends a TIPC datagram to one or more...

Privilege Escalation

linux-azure:hirsute is vulnerable to privilege escalation. aspeedlpcctrlmmap in drivers/soc/aspeed/aspeed-lpc-ctrl.c allows an attacker to access the Aspeed LPC control interface and to overwrite memory in the kernel and potentially execute privileges, aka CID-b49a0e69a7b1. This occurs because a...
