UBUNTU-CVE-2024-36971: High severity ubuntu/linux-azure vulnerability

Q: What level of access does an attacker need to exploit this issue?

The reported CVSS vector requires local access and low privileges. No user interaction is required.

Q: What is the potential impact if exploitation succeeds?

The vulnerability can result in use-after-free behavior and is rated as having high confidentiality, integrity, and availability impact.

Q: Which Ubuntu kernel package families are listed as affected?

The listed software includes ubuntu/linux, ubuntu/linux-fips, ubuntu/linux-azure, ubuntu/linux-aws-fips, ubuntu/linux-azure-fips, ubuntu/linux-gcp-fips, ubuntu/linux-gcp, and ubuntu/linux-oracle.

Q: Is network reachability alone sufficient for exploitation?

No. The provided CVSS vector identifies the attack vector as local, rather than network-based.

Updated

In the Linux kernel, the following vulnerability has been resolved: net: fix dstnegativeadvice() race dstnegativeadvice() does not enforce proper RCU rules when sk->dstcache must be cleared, leading to possible UAF. RCU rules are that we must first clear sk->skdstcache, then call dstrelease(olddst). Note that skdstreset(sk) is implementing this protocol correctly, while dstnegativeadvice() uses the wrong order. Given that ip6negativeadvice() has special logic against RTFCACHE, this means each of the three ->negativeadvice() existing methods must perform the skdstreset() themselves. Note the check against NULL dst is centralized in dstnegativeadvice(), there is no need to duplicate it in various callbacks. Many thanks to Clement Lecigne for tracking this issue. This old bug became visible after the blamed commit, using UDP sockets.

Frequently Asked Questions

What level of access does an attacker need to exploit this issue?

The reported CVSS vector requires local access and low privileges. No user interaction is required.

What is the potential impact if exploitation succeeds?

The vulnerability can result in use-after-free behavior and is rated as having high confidentiality, integrity, and availability impact.

Which Ubuntu kernel package families are listed as affected?

The listed software includes ubuntu/linux, ubuntu/linux-fips, ubuntu/linux-azure, ubuntu/linux-aws-fips, ubuntu/linux-azure-fips, ubuntu/linux-gcp-fips, ubuntu/linux-gcp, and ubuntu/linux-oracle.

Is network reachability alone sufficient for exploitation?
