kernel: x86: fix user address masking non-canonical speculation issue
A flaw was found in the Linux kernel's handling of user address masking on x86 architectures. This vulnerability, similar to "Meltdown Lite," allows for speculative execution a CPU optimization technique to be exploited due to incorrect handling of non-canonical memory accesses in kernel space. A...

AZL-52590 CVE-2024-50102 affecting package kernel 6.6.150.1-1
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-2024-50102
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...
