CVE-2025-38392

CVE-2025-38392 (Linux kernel) describes a concurrency issue in the idpf driver where a control queue mutex (cq_lock) is held across operations that may sleep, triggering warnings during module load when VIRTCHNL2_CAP_MACFILTER is ON. The fix converts cq_lock from a mutex to a spinlock to avoid sl...

CVE-2025-38388

CVE-2025-38388 concerns the Linux kernel’s ARM Firmware Framework for ARMv8-A (FFA). The issue stems from using a mutex to protect the notifier hashtable accesses, which could sleep in atomic context and trigger warnings like “sleeping function called from invalid context.” Connected documents co...

CVE-2025-38388
