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

  - In the Linux kernel, the following vulnerability has been resolved: SUNRPC: auth_gss: fix memory leaks in     XDR decoding error paths The gssx_dec_ctx(), gssx_dec_status(), and gssx_dec_name() functions allocate     memory via gssx_dec_buffer(), which calls kmemdup(). When a subsequent decode operation fails, these     functions return immediately without freeing previously allocated buffers, causing memory leaks. The leak     in gssx_dec_ctx() is particularly relevant because the caller (gssp_accept_sec_context_upcall) initializes     several buffer length fields to non-zero values, resulting in memory allocation: struct gssx_ctx rctxh = {     .exported_context_token.len = GSSX_max_output_handle_sz, .mech.len = GSS_OID_MAX_LEN,     .src_name.display_name.len = GSSX_max_princ_sz, .targ_name.display_name.len = GSSX_max_princ_sz }; If, for     example, gssx_dec_name() succeeds for src_name but fails for targ_name, the memory allocated for     exported_context_token, mech, and src_name.display_name remains unreferenced and cannot be reclaimed. Add     error handling with goto-based cleanup to free any previously allocated buffers before returning an error.
    (CVE-2026-45870)
