CVE-2026-90359

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. When BPF programs are attached to functions that return 16-byte values using specific trampoline types such as fexit, fmodret, fsession, or structops, the BPF trampoline incorrectly preserves only 8 bytes of the return...

CVE-2026-90359

CVE-2026-90359 affects the Linux kernel BPF subsystem. The btf_distill_func_proto() function, which builds the function model for fentry/fexit/fmod_ret/fsession trampolines and struct_ops , has accepted 16-byte __int128 return values since the trampoline was introduced. However, the BPF trampolin...

Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel version 5.5. It arises because BPF trampolines retain only 8 bytes of return values, while btfdistillfuncproto expects a 16-byte int128 return value. For target return types such as fexit, fmodret, fsession, and its variants like multi, as well as...
