CVE-2026-93202

CVE-2026-93202 is a deadlock vulnerability in the Linux kernel i3c master driver. The function i3c_master_register_new_i3c_devs() calls device_register() while holding i3c_bus_normaluse_lock() (a read-side rwsem). The resulting device probe callback may invoke I3C helpers that re-acquire the same...

CVE-2026-89446

CVE-2026-89446 affects the Linux kernel iommufd subsystem. The root cause is in the error-handling path of iommufd_take_all_iova_rwsem(): when xa_store() fails to insert the current IOAS into the ioas_list xarray, the subsequent call to iommufd_release_all_iova_rwsem() only unwinds entries alread...

CVE-2026-80856

CVE-2026-80856 is a lock leak in the Linux kernel FUSE subsystem. In fuse_do_setattr(), the function acquires filemap_invalidate_lock() for a DAX truncate but fails to release it when write_inode_now() returns an error (e.g., the FUSE daemon returns -EIO ). The leaked rwsem causes any subsequent ...
