[local] Linux Kernel - Local Privilege Escalation

This local privilege escalation exploit chains two Linux kernel vulnerabilities, CVE-2026-43284 (CVSS 8.8) and CVE-2026-43500 (CVSS 7.8), to perform arbitrary writes to the page-cache and modify setuid binaries or sensitive files. The exploit affects Linux kernel versions from 4.11 up to but not including specific fixed versions, such as 5.10.255, 5.15.205, 6.1.171, 6.6.138, 6.12.87, 6.18.28, and 7.0.5 for CVE-2026-43284. The primary mitigation is to upgrade the kernel to the corresponding fixed version for each affected branch.

The vulnerability is not a single bug, but a strategic chain of two distinct flaws that allow an unprivileged attacker to bypass standard filesystem write protections. ### Vulnerability Chain: 1. **CVE-2026-43284 (xfrm-ESP):** A logic error in the ESP protocol implementation when Extended Sequence Numbers (ESN) are active. This flaw allows a local user to perform arbitrary 4-byte writes directly into the page-cache. 2. **CVE-2026-43500 (RxRPC):** A flaw in the RxRPC protocol that facilitates in-place decryption of data within page-cache pages. ### Impact Analysis: By chaining these vulnerabilities, an attacker can modify the memory-resident pages of setuid binaries (e.g., `/usr/bin/su` or `/usr/bin/sudo`) or sensitive system files (e.g., `/etc/passwd`). Because the modification occurs in the page-cache, the attacker effectively "poison" the execution environment. **Key Advantages for Attacker:** * **Stability:** No race conditions involved. * **Reliability:** Near 100% success rate on tested environments. * **Stealth:** Does not trigger kernel panics or system instability upon failure. * **Persistence:** Affects kernels spanning nearly 9 years (2017-01-17 to 2026-05-10). --- ## Affected Systems (Verified) The following distributions have been tested and confirmed vulnerable: * **Ubuntu:** 24.04.4 / 25.10 / 26.04 * **RHEL:** 10.1 * **openSUSE:** Tumbleweed * **CentOS Stream:** 10 * **AlmaLinux:** 10 * **Fedora:** 44 --- ## Proof of Concept (PoC) ### Execution Flow: ```bash # Compiling the exploit tool $ gcc -O2 kukurigu.c -o kukurigu_exploit # Running the exploit against a target binary $ ./kukurigu_exploit --target /usr/bin/su --method esp [+] Initializing Kukurigu LPE engine...
