CVE-2026-45922

In CVE-2026-45922, the Linux kernel RDMA/mlx5 GET_DATA_DIRECT_SYSFS_PATH handler leaks memory: it allocates device-path memory with kobject_get_path() and, if the path length exceeds the output buffer, returns -ENOSPC without freeing, causing a memory leak. The fix adds a kfree() in the error pat...
