Overview
CVE-2026-90128 is a known-severity vulnerability. It was published on September 17, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
vdpa/mlx5: fix wrong list iterated in add_direct_chain error path
In add_direct_chain(), newly allocated direct MR entries are added to
the local list 'tmp', which is spliced into mr->head only on success.
On the error path, the cleanup loop was incorrectly iterating over
mr->head instead of tmp.
Fix by iterating over 'tmp' in the err_alloc cleanup path.
