medium Tenable Cloud Security Plugin ID 461551

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: USB: serial: keyspan_pda: fix
information leak The write() callback is supposed to return the number of characters accepted or a
negative errno. Since the addition of write fifo support the keyspan_pda implementation will however
return the number characters submitted to the device if the write urb is not already in use. If this
number is larger than the number of characters passed to write(), the line discipline continues writing
data from beyond the tty write buffer. Fix the information leak by making sure that
keyspan_pda_write_start() returns zero on success as intended. (CVE-2026-64336)

Solution

Update the linux library and its related packages to version 6.1.180-1 or later.
