Vulnerability from fkie_nvd - Published: 2026-08-15 06:21 - Updated: 2026-08-17 06:18
Severity
Summary
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.
