      <title>CVE-2025-38083 — net_sched: prio: fix a race in prio_tune()</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2025-38083</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Linux, Siemens SIMATIC S7-1500 CPU 1518-4 PN/DP MFP, Siemens SIMATIC S7-1500 CPU 1518F-4 PN/DP MFP, Siemens SIPLUS S7-1500 CPU 1518-4 PN/DP MFP&lt;/p&gt;
&lt;p&gt;In the Linux kernel, the following vulnerability has been resolved:&lt;/p&gt;
&lt;p&gt;net_sched: prio: fix a race in prio_tune()&lt;/p&gt;
&lt;p&gt;Gerrard Tai reported a race condition in PRIO, whenever SFQ perturb timer
fires at the wrong time.&lt;/p&gt;
&lt;p&gt;The race is as follows:&lt;/p&gt;
&lt;p&gt;CPU 0                                 CPU 1
[1]: lock root
[2]: qdisc_tree_flush_backlog()
[3]: unlock root
 |
 |                                    [5]: lock root
 |                                    [6]: rehash
 |                                    [7]: qdisc_tree_reduce_backlog()
 |
[4]: qdisc_put()&lt;/p&gt;
&lt;p&gt;This can be abused to underflow a parent&amp;#39;s qlen.&lt;/p&gt;
&lt;p&gt;Calling qdisc_purge_queue() instead of qdisc_tree_flush_backlog()
should fix the race, because all packets will be purged from the qdisc
before releasing the lock.&lt;/p&gt;</description>

&lt;p&gt;Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
