CVE-2026-80640
A flaw was found in the Linux kernel's CXL subsystem firmware control cxl/fwctl. A buffer overflow vulnerability exists in the cxlctlgetsupportedfeatures function due to improper initialization of an array size. This could lead to a system crash, resulting in a denial of service DoS...
CVE-2026-80639
A flaw was found in the Linux kernel's cxl/test module. A buffer overflow vulnerability, a type of memory corruption, exists within the setupxormapping function. This flaw could allow a local user to trigger a runtime assertion failure, potentially leading to system instability or a denial of...
CVE-2026-80662
A flaw was found in the Linux kernel's Compute Express Link CXL subsystem. An incorrect definition of the CXLHEADERLOGSIZE led to an out-of-bounds read when processing RAS capability structures. This vulnerability allows a local attacker to read sensitive kernel stack memory, potentially leading ...
