      <title>CVE-2026-64370 — posix-cpu-timers: Fix pid refcount leak in do_cpu_nanosleep() error path</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-64370</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;posix-cpu-timers: Fix pid refcount leak in do_cpu_nanosleep() error path&lt;/p&gt;
&lt;p&gt;In do_cpu_nanosleep(), posix_cpu_timer_create() takes a pid reference
via get_pid() and stores it in timer.it.cpu.pid. If the subsequent
posix_cpu_timer_set() call fails, the function returns immediately
without calling posix_cpu_timer_del() to release the pid reference,
causing a leak.&lt;/p&gt;
&lt;p&gt;Fix it by calling posix_cpu_timer_del() before the unlock-and-return
on the error path, consistent with the other exit paths in the same
function.&lt;/p&gt;</description>
