Re: CVE-2024-36905: Linux kernel: Divide-by-zero on shutdown of TCP_SYN_RECV sockets

Posted by Solar Designer on Nov 12

NIST doesn't appear to provide their own CVSS vectors/scores lately.
However, they republish (with attribution) some third-party ones, this
time from CISA-ADP. The CISA-ADP CVSS vector for this vulnerability
specifies that it not only is network-reachable, but also that it has
High impact not only on Availability, but also on Confidentiality and
Integrity. This results in a CVSSv3.1 score of 9.8. Even merely
correcting the vector not to...

Hi,

I think the source for the CISA-ADP data is at [1]. For this specific CVE, the relevant file would be [2]. Their readme
has a section at the bottom, where they encourage feedback:

I’m aware of at last one prior case where a similar case of (IMHO) overblown CVSS scores was discussed in an issue on
this particular GitHub project [3].

Somebody seems to already have opened a ticket for this CVE, too: [4]

Re: Xen Security Advisory 464 v2 (CVE-2024-45819) - libxl leaks data to PVH guests via ACPI tables

Posted by Andrew Cooper on Nov 12

Data are leaked into the PVShim guest, but it is the shim Xen
(exclusively) which has access to the ACPI tables.

The guest which has been shim'd can't architecturally access the leaked
data.

Re: Xen Security Advisory 464 v2 (CVE-2024-45819) - libxl leaks data to PVH guests via ACPI tables

Posted by Demi Marie Obenour on Nov 12

Is this unconditional (perhaps because the relevant data gets zeroed out
by the shim), or does it only apply when the PV guest can't extract data
from the shim's memory? For instance, 32-bit PV guests aren't security
supported anymore, but the PV shim isn't supposed to rely on the
security of the shim itself, only of the rest of the system.
