CVE-2025-38334 x86/sgx: Prevent attempts to reclaim poisoned pages
In the Linux kernel, the following vulnerability has been resolved: x86/sgx: Prevent attempts to reclaim poisoned pages TL;DR: SGX page reclaim touches the page to copy its contents to secondary storage. SGX instructions do not gracefully handle machine checks. Despite this, the existing SGX code...
Adaptive and Efficient Dynamic Memory Management for Hardware Enclaves
The second version of Intel Software Guard Extensions Intel SGX, or SGX2, adds dynamic management of enclave memory and threads. The first version required the address space and thread counts to be fixed before execution. The Enclave Dynamic Memory Management EDMM feature of SGX2 has the potentia...
CVE-2020-8936
An arbitrary memory overwrite vulnerability in Asylo versions up to 0.6.0 allows an attacker to make a host call to UntrustedCall. UntrustedCall failed to validate the buffer range within sgxparams and allowed the host to return a pointer that was an address within the enclave memory. This allowe...

CVE-2021-22552
An untrusted memory read vulnerability in Asylo versions up to 0.6.1 allows an untrusted attacker to pass a syscall number in MessageReader that is then used by sysno and can bypass validation. This can allow the attacker to read memory from within the secure enclave. We recommend updating to Asy...
