CVE-2024-26762

CVE-2024-26762 (Linux kernel) concerns CXL error handling. The fix addresses a crash: after unbinding the memory device (cxl_mem) following a RAS event, a later AER notification could access unmapped registers. The patch adds a check to verify memdev binding before reaping status register values,...

CVE-2024-26761

CVE-2024-26761 : Linux kernel fix in the cxl/pci HDM setup to prevent a system hang when the DVSEC CXL range is not found in a CFMWS window. If the Host Physical Address (HPA) is not a System Physical Address (SPA), the CXL range may not map to a CFMWS window, causing the HDM decoder to be disabl...

kernel: Linux kernel CXL driver: Use-after-free vulnerability leading to system instability or privilege escalation

A flaw was found in the Linux kernel's CXL driver. This vulnerability, a use-after-free, allows a local user to cause system instability or a denial of service. The issue arises when the cxlparsecfmws function attempts to use memory that has already been released. This could potentially lead to...
