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

  - binder: cache secctx size before release zeroes it binder_transaction() bounds the scatter-gather buffer     area with sg_buf_end_offset and subtracts the aligned LSM context size because the secctx is written at     the tail of that area. The subtraction reads lsmctx.len, but that field has already been cleared by the     time the line runs: security_secid_to_secctx(secid, &lsmctx) /* lsmctx.len set */ lsmctx_aligned_size =     ALIGN(lsmctx.len, sizeof(u64)) extra_buffers_size += lsmctx_aligned_size ...
    security_release_secctx(&lsmctx) /* memset zeroes len */ ... sg_buf_end_offset = sg_buf_offset +     extra_buffers_size - ALIGN(lsmctx.len, sizeof(u64)) /* ALIGN(0,8) */ security_release_secctx() does     memset(cp, 0, sizeof(*cp)), so lsmctx.len reads back as 0 and the subtraction contributes nothing, leaving     sg_buf_end_offset too large by the aligned secctx size on every transaction to a txn_security_ctx node.
    Each BINDER_TYPE_PTR object then derives buf_left = sg_buf_end_offset - sg_buf_offset as the sole upper     bound on its copy, so the inflated end offset lets the copy run into the bytes that already hold the     secctx. The aligned size must therefore be cached before release rather than re-read from the now-cleared     field. Fix by caching it in lsmctx_aligned_size at function scope when it is first computed and     subtracting lsmctx_aligned_size instead of re-reading lsmctx.len after release. Reuse the same value for     the earlier buf_offset computation. (CVE-2026-68458)

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