CVE-2026-80768: HID: ft260: fix stack-use-after-return write in I2C read race

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.17% (FIRST EPSS).
  • Fixed version: Linux Linux 2b907001e8a83cdb71e899fd3d77ab51e2c03f10, 460514d46e8892189fc933a1b4433811cfa5c309, 5aa5a1b7cc4b4bec5497ad9ef113fdfe37b232f3.

Low priority for now. Upgrade to Linux Linux 2b907001e8a83cdb71e899fd3d77ab51e2c03f10, 460514d46e8892189fc933a1b4433811cfa5c309, 5aa5a1b7cc4b4bec5497ad9ef113fdfe37b232f3 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: HID: ft260: fix stack-use-after-return write in I2C read race ft260_i2c_read() points dev->read_buf at a caller-supplied buffer (often an on-stack variable), arms a completion and waits up to five seconds for the device to return the data. The HID input callback ft260_raw_event() runs in the input/IRQ path, independent of the dev->lock mutex held by the read path, and copies the device-supplied payload into dev->read_buf after a plain NULL check. These two paths share read_buf, read_idx and read_len with no serialization. If the device delays its response until the read times out, ft260_i2c_read() resets the controller, clears read_buf and returns, unwinding the stack frame the buffer lived in. A response that arrives at that moment lets ft260_raw_event() pass the NULL check and then memcpy() the device-controlled payload into the now-freed stack location, a bounded but attacker-influenced stack-use-after-return write triggerable by malicious or malfunctioning hardware. Add a dedicated spinlock that serializes every access to read_buf, read_idx and read_len. ft260_raw_event() now holds it across the NULL check, the memcpy and the index update, while the read path takes it when arming and when clearing the buffer, so the teardown can no longer slip between the check and the copy.
