CVE-2024-50102

CVE-2024-50102 : The connected advisories indicate a Linux kernel x86 issue where using the high address bit to classify user vs. kernel space enabled a speculative-execution leak for non-canonical addresses. The root cause involves non-canonical address handling and an evolving AC/bit behavior a...

CVE-2024-50102 x86: fix user address masking non-canonical speculation issue

In the Linux kernel, the following vulnerability has been resolved: x86: fix user address masking non-canonical speculation issue It turns out that AMD has a "Meltdown Litetm" issue with non-canonical accesses in kernel space. And so using just the high bit to decide whether an access is in user...

CVE-2024-50112: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: x86/lam: Disable ADDRESSMASKING in most cases Linear Address Masking LAM has a weakness related to transient execution as described in the SLAM paper1. Unless Linear Address Space Separation LASS is enabled this weakness may be...
