      <title>CVE-2026-90143 — net: kcm: Hold RCU read lock while running BPF parser</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-90143</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;net: kcm: Hold RCU read lock while running BPF parser&lt;/p&gt;
&lt;p&gt;kcm_parse_func_strparser() calls bpf_prog_run_pin_on_cpu() which
prevents CPU migration, but does not establish an RCU read-side
critical section. Consequently, BPF map operations can trigger
WARN_ON_ONCE(!bpf_rcu_lock_held()) when called from the KCM strparser
program.&lt;/p&gt;
&lt;p&gt;Hold the RCU read lock while running the program.&lt;/p&gt;</description>
