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...

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]
