      <title>CVE-2025-38701 — ext4: do not BUG when INLINE_DATA_FL lacks system.data xattr</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2025-38701</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Linux, Siemens SIMATIC CN 4100, 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;ext4: do not BUG when INLINE_DATA_FL lacks system.data xattr&lt;/p&gt;
&lt;p&gt;A syzbot fuzzed image triggered a BUG_ON in ext4_update_inline_data()
when an inode had the INLINE_DATA_FL flag set but was missing the
system.data extended attribute.&lt;/p&gt;
&lt;p&gt;Since this can happen due to a maiciouly fuzzed file system, we
shouldn&amp;#39;t BUG, but rather, report it as a corrupted file system.&lt;/p&gt;
&lt;p&gt;Add similar replacements of BUG_ON with EXT4_ERROR_INODE() ii
ext4_create_inline_data() and ext4_inline_data_truncate().&lt;/p&gt;</description>
