Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: A Local Privilege Escalation (LPE) flaw in the Linux kernel's `futex_requeue` function.β¦
π **Privileges**: Escalates from **User** to **Root** (UID 0). π **Data Access**: Full read/write access to all system files, memory, and configurations. π΅οΈ **Impact**: Complete compromise of the host system.
Q5Is exploitation threshold high? (Auth/Config)
β‘ **Threshold**: **LOW**. π **Auth**: Requires **Local** access only (no remote exploit). π **Config**: No special configuration needed; just execute the exploit binary with user-level permissions. π
Q6Is there a public Exp? (PoC/Wild Exploitation)
π₯ **Public Exp**: **YES**. π§Ά **Famous Exploit**: **Towelroot** (widely known). π **PoCs**: Available on GitHub (e.g., `timwr/CVE-2014-3153`, `geekben/towelroot`). π± **Platforms**: Tested on x86 and ARM architectures.
Q7How to self-check? (Features/Scanning)
π **Check**: Scan for Linux Kernel version **β€ 3.14.5**. π **Indicator**: Presence of vulnerable `futex` implementation. π οΈ **Tool**: Use kernel version detection tools or check `uname -r`.β¦
π§ **Workaround**: If patching is impossible, **restrict local user access**. π **Mitigation**: Disable unnecessary local accounts, use AppArmor/SELinux to limit capabilities, and monitor for suspicious root processes.β¦
