CVE-2026-89571
This is an out-of-bounds read in the Linux kernel's CXL (Compute Express Link) features subsystem. The fwctl_cmd_rpc() function copies user-supplied data into a fixed-size buffer, but the downstream cxlctl_set_feature() callback validates the user-controlled op_size only from below, never against...

CVE-2026-80640
CVE-2026-80640 affects the CXL firmware control (fwctl) subsystem of the Linux kernel . The root cause is in cxlctl_get_supported_features(), where num_entries is not initialized early enough, causing the kernel's Fortify runtime protection to detect a potential 48-byte write to a zero-size buffe...

CVE-2026-64101
A flaw was found in the Linux kernel's fwctl component. Insufficient validation of the Remote Procedure Call RPC input buffer size in the pdsfcfwrpc function can lead to an out-of-bounds read. A local attacker could exploit this vulnerability by providing a specially crafted RPC input, potentiall...
