      <title>CVE-2026-90417 — RDMA/cxgb4: Fix dereg_skb leak and double free in write_tpt_entry()</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-90417</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Linux&lt;/p&gt;
&lt;p&gt;In the Linux kernel, the following vulnerability has been resolved:&lt;/p&gt;
&lt;p&gt;RDMA/cxgb4: Fix dereg_skb leak and double free in write_tpt_entry()&lt;/p&gt;
&lt;p&gt;When the device is in the fatal error state, write_tpt_entry() returns -EIO
before handing the caller&amp;#39;s preallocated skb to the transmit path; its
allocation-failure returns do the same. c4iw_dereg_mr() ignores the error
and frees mhp, leaking mhp-&amp;gt;dereg_skb. c4iw_get_dma_mr() instead frees the
skb a second time after dereg_mem() already consumed it, a double free.&lt;/p&gt;
&lt;p&gt;Make write_tpt_entry() the sole owner of a non-NULL skb, freeing it on
every return preceding handoff to c4iw_ofld_send(): fatal error, tpt and
stag allocation failure. c4iw_ofld_send() consumes the skb on success and
error alike, so drop the redundant kfree_skb() in c4iw_get_dma_mr() after
dereg_mem().&lt;/p&gt;</description>
