      <title>CVE-2026-43365 — xfs: fix undersized l_iclog_roundoff values</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-43365</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;xfs: fix undersized l_iclog_roundoff values&lt;/p&gt;
&lt;p&gt;If the superblock doesn&amp;#39;t list a log stripe unit, we set the incore log
roundoff value to 512.  This leads to corrupt logs and unmountable
filesystems in generic/617 on a disk with 4k physical sectors...&lt;/p&gt;
&lt;p&gt;XFS (sda1): Mounting V5 Filesystem ff3121ca-26e6-4b77-b742-aaff9a449e1c
XFS (sda1): Torn write (CRC failure) detected at log block 0x318e. Truncating head block from 0x3197.
XFS (sda1): failed to locate log tail
XFS (sda1): log mount/recovery failed: error -74
XFS (sda1): log mount failed
XFS (sda1): Mounting V5 Filesystem ff3121ca-26e6-4b77-b742-aaff9a449e1c
XFS (sda1): Ending clean mount&lt;/p&gt;
&lt;p&gt;...on the current xfsprogs for-next which has a broken mkfs.  xfs_info
shows this...&lt;/p&gt;
