CVE-2026-80663

CVE-2026-80663 affects the Linux kernel's tools/power/x86/intel-speed-select daemon. The vulnerability is a symlink-based pidfile clobbering flaw: the daemon uses a fixed pidfile path under /tmp and opens it without O_NOFOLLOW, allowing a local unprivileged user to pre-create a symlink at that pa...

CVE-2026-80662

CVE-2026-80662 affects the Linux kernel's CXL (Compute Express Link) RAS subsystem . The CXL_HEADERLOG_SIZE constant was defined as 512 bytes , eight times the actual 64-byte on-device Header Log in the CXL r4.0 RAS Capability Structure. This causes header_log_copy() to overrun the 88-byte iomap ...
