### [CVE-2015-3636](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-3636) ![](https://img.shields.io/static/v1?label=Product&message=n%2Fa&color=blue) ![](https://img.shields.io/static/v1?label=Version&message=n%2Fa&color=blue) ![](https://img.shields.io/static/v1?label=Vulnerability&message=n%2Fa&color=brighgreen) ### Description The ping_unhash function in net/ipv4/ping.c in the Linux kernel before 4.0.3 does not initialize a certain list data structure during an unhash operation, which allows local users to gain privileges or cause a denial of service (use-after-free and system crash) by leveraging the ability to make a SOCK_DGRAM socket system call for the IPPROTO_ICMP or IPPROTO_ICMPV6 protocol, and then making a connect system call after a disconnect. ### POC #### Reference - http://www.oracle.com/technetwork/topics/security/linuxbulletinjan2016-2867209.html - http://www.ubuntu.com/usn/USN-2632-1 #### Github - https://github.com/ARPSyndicate/cvemon - https://github.com/CVEDB/PoC-List - https://github.com/CVEDB/awesome-cve-repo - https://github.com/CVEDB/top - https://github.com/GhostTroops/TOP - https://github.com/JERRY123S/all-poc - https://github.com/R0B1NL1N/linux-kernel-exploitation - https://github.com/SmllXzBZ/AEGPaper - https://github.com/Technoashofficial/kernel-exploitation-linux - https://github.com/a7vinx/CVE-2015-3636 - https://github.com/ambynotcoder/C-libraries - https://github.com/android-rooting-tools/libpingpong_exploit - https://github.com/askk/libping_unhash_exploit_POC - https://github.com/betalphafai/cve-2015-3636_crash - https://github.com/cyberanand1337x/bug-bounty-2022 - https://github.com/debugfan/rattle_root - https://github.com/fi01/CVE-2015-3636 - https://github.com/hktalent/TOP - https://github.com/idhyt/androotzf - https://github.com/jbmihoub/all-poc - https://github.com/kdn111/linux-kernel-exploitation - https://github.com/khanhdn111/linux-kernel-exploitation - https://github.com/khanhdz-06/linux-kernel-exploitation - https://github.com/khanhdz191/linux-kernel-exploitation - https://github.com/khanhhdz/linux-kernel-exploitation - https://github.com/khanhhdz06/linux-kernel-exploitation - https://github.com/khanhnd123/linux-kernel-exploitation - https://github.com/knd06/linux-kernel-exploitation - https://github.com/ludongxu/cve-2015-3636 - https://github.com/ndk191/linux-kernel-exploitation - https://github.com/ne2der/AKLab - https://github.com/skbasava/Linux-Kernel-exploit - https://github.com/ssr-111/linux-kernel-exploitation - https://github.com/tangsilian/android-vuln - https://github.com/weeka10/-hktalent-TOP - https://github.com/xairy/linux-kernel-exploitation
