      <title>CVE-2026-61495 — TinyUSB 0.21.0 Out-of-Bounds Write via mtp_container_get_string()</title>
      <link>https://db.gcve.eu/vuln/cve-2026-61495</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; hathach TinyUSB&lt;/p&gt;
&lt;p&gt;TinyUSB through 0.21.0, fixed in commit e85c2b8, contains an out-of-bounds write vulnerability in the MTP device class helper mtp_container_get_string() in src/class/mtp/mtp.h that allows a malicious USB host to corrupt adjacent memory by supplying a crafted MTP string with an unbounded character count. Attackers can exploit the unchecked memcpy operation copying up to 510 bytes into a fixed-size destination buffer to achieve code execution or cause a denial of service on the TinyUSB MTP device.&lt;/p&gt;</description>
