The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - tee: shm: fix shm leak in register_shm_helper() register_shm_helper() allocates shm before calling     iov_iter_npages(). If iov_iter_npages() returns 0, the function jumps to err_ctx_put and leaks shm. This     can be triggered by TEE_IOC_SHM_REGISTER with struct tee_ioctl_shm_register_data where length is 0. Jump     to err_free_shm instead. (CVE-2026-53210)

Note that Nessus relies on the presence of the package as reported by the vendor.
