Input: ims-pcu - fix out-of-bounds read in ims_pcu_irq() debug logging

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: 0.22% (FIRST EPSS).
  • Fixed version: Linux Linux 20fbf3ca0259d00664d1ede88837e1f11b49a88e, 3fd7c0ace245334f2a0bd29fdcb680ad56e9b275, 403b0a6970b1084bb27907c0f8225801fdd0fe1d.

Low priority for now. Upgrade to Linux Linux 20fbf3ca0259d00664d1ede88837e1f11b49a88e, 3fd7c0ace245334f2a0bd29fdcb680ad56e9b275, 403b0a6970b1084bb27907c0f8225801fdd0fe1d or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

In the Linux kernel, the following vulnerability has been resolved: Input: ims-pcu - fix out-of-bounds read in ims_pcu_irq() debug logging The debug logging in ims_pcu_irq() unconditionally prints data from pcu->urb_in_buf. However, if the interrupt fired for pcu->urb_ctrl, the actual data resides in pcu->urb_ctrl_buf. If urb->actual_length for the control URB exceeds pcu->max_in_size, this leads to an out-of-bounds read. Fix this by printing from the correct buffer associated with the URB.
