CVE-2026-90358

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter x86 trampoline. When processing 128-bit arguments, the system incorrectly calculates the required stack size for saving registers. This under-allocation leads to memory corruption by overwriting adjacent stack slots. A local attack...

CVE-2026-90358

In the Linux kernel, the following vulnerability has been resolved: bpf, x86: Fix trampoline stack size for 128-bit arguments btfdistillfuncproto accepts a function argument up to 16 bytes, so a 128-bit scalar such as int128 reaches the x86 trampoline with argsize == 16. But the current...
