      <title>CVE-2026-90266 — btrfs: zoned: don't force read-only on transient -EAGAIN from reloc merge</title>
      <link>https://db.gcve.eu/vuln/cve-2026-90266</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;btrfs: zoned: don&amp;#39;t force read-only on transient -EAGAIN from reloc merge&lt;/p&gt;
&lt;p&gt;On a zoned FS, btrfs_delayed_refs_rsv_refill() returns -EAGAIN whenever
the over-committed metadata plus the zone_unusable bytes exceeds the
usable size in a metadata block-group to avoid heavy over-commit of
metadata and early ENOSPC in one transaction.&lt;/p&gt;
&lt;p&gt;If this happens while doing reclaim, the transaction is getting aborted.&lt;/p&gt;
&lt;p&gt;Treat -EAGAIN as a soft, retryable condition in case of block-group
reclaim.&lt;/p&gt;</description>
