CVE-2022-50733: usb: idmouse: fix an uninit-value in idmouse_open

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: 0.28% (FIRST EPSS).
  • Fixed version: Linux Linux 1eae30c0113dde7522088231584d62415011a035, 20b8c456df584ebb2387dc23d40ebe4ff334417c, 6163a5ae097bc78fa26c243fb384537e25610fd7.

Low priority for now. Upgrade to Linux Linux 1eae30c0113dde7522088231584d62415011a035, 20b8c456df584ebb2387dc23d40ebe4ff334417c, 6163a5ae097bc78fa26c243fb384537e25610fd7 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: usb: idmouse: fix an uninit-value in idmouse_open In idmouse_create_image, if any ftip_command fails, it will go to the reset label. However, this leads to the data in bulk_in_buffer[HEADER..IMGSIZE] uninitialized. And the check for valid image incurs an uninitialized dereference. Fix this by moving the check before reset label since this check only be valid if the data after bulk_in_buffer[HEADER] has concrete data. Note that this is found by KMSAN, so only kernel compilation is tested.
