# CVE-2024-36971: Android Kernel Remote Code Execution Vulnerability

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run Android Kernel. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2024-08-07, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2024-08-28 ; treat that as the outer limit, not the target.
- EPSS 2.7% , percentile 86: FIRST’s model estimates a 2.7% chance of exploitation activity in the next 30 days, higher than 86% of all scored CVEs (elevated). EPSS is a probability, not a verdict.
- Needs local access needed. Lower urgency for most teams unless an attacker could already run code on the machine.

## What it is

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.
