      <title>CVE-2026-95818 — AT_SECURE program buffer overflow via $ORIGIN processing</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-95818</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; The GNU C Library glibc&lt;/p&gt;
&lt;p&gt;A stack-based buffer overflow in the dynamic loader (ld.so) of the GNU C Library (glibc) versions 2.14 through 2.44 allows a local attacker to crash or corrupt the memory of setuid/setgid (AT_SECURE) programs.&lt;/p&gt;
&lt;p&gt;When such a program&amp;#39;s DT_RPATH or DT_RUNPATH begins with $ORIGIN and is followed by NUL or &amp;#39;/&amp;#39; the loader both reads past the end of the path buffer and writes past the end of a stack-allocated internal buffer. The corrupted loader stack can lead to a loader crash (denial of service) and limited disclosure of process memory.&lt;/p&gt;</description>
