CVE-2026-46081

In the Linux kernel, the following vulnerability has been resolved: crypto: acomp - fix wrong pointer stored by acomp_save_req() acomp_save_req() stores &req->chain in req->base.data.

Since data points to the chain member, all subsequent field accesses are at a wrong offset, resulting in memory corruption. The issue occurs when an asynchrono
