cve-2018-4233

CVE-2018-4233 Exploit for CVE-2018-4233, a bug in the JIT compiler of WebKit. Tested on Safari 11.0.3 on macOS 10.13.3. For more details see https://saelo.github.io/presentations/blackhatus18attackingclientsidejitcompilers.pdf The exploit gains arbitrary memory read/write by constructing the addr...

CVE-2026-93135

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF. When the Just-In-Time JIT compiler is unavailable or fails, BPF programs that use inlined helper functions are processed by the interpreter with unpatched helper identifiers. This incorrect processing can lead to an instruction...

CVE-2026-92518

A flaw was found in the Linux kernel's RISC-V BPF JIT compiler. When Control-Flow Integrity CFI with Clang is enabled, an error in calculating the tail call jump offset can lead to kernel stack corruption. This issue causes the system to improperly adjust the stack pointer, which can result in...

CVE-2026-98572

A flaw was found in the Linux kernel's extended Berkeley Packet Filter eBPF Just-In-Time JIT compiler on 32-bit MIPS systems. An instruction generation error during 64-bit jump comparisons causes negative numeric constants to be incorrectly evaluated against a hardware register instead of the...

jitsploitation

jitsploitation iOS browser exploit for CVE-2020-9802, an old JIT bug. This is an exploit for a popular JIT compiler bug in the WebKit engine for macOS and iOS originally documented by Project Zero. I re-implemented the exploit for this bug as an exercise in learning browser exploitation. Video...

CVE-2026-90195

A flaw was found in the Linux kernel's RISC-V 64-bit RV64 Just-In-Time JIT compiler for Berkeley Packet Filter BPF programs. The RV64 JIT fails to perform proper sign-extension for signed 1-byte and 2-byte kernel function kfunc arguments. This oversight can lead to incorrect processing of data...

kernel: bpf: Support for hardening against JIT spraying

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF Just-In-Time JIT compiler. The BPF JIT allocator reuses memory space, and when new code is written, an indirect jump into the new program can reuse a branch prediction left behind by an old program. This could allow an attacker to...
