Title
can: etas_es58x: allow partial RX URB allocation to succeed
Summary
In the Linux kernel, the following vulnerability has been resolved:
can: etas_es58x: allow partial RX URB allocation to succeed
When es58x_alloc_rx_urbs() fails to allocate the requested number of
URBs but succeeds in allocating some, it returns an error code.
This causes es58x_open() to return early, skipping the cleanup label
'free_urbs', which leads to the anchored URBs being leaked.
As pointed out by maintainer Vincent Mailhol, the driver is designed
to handle partial URB allocation gracefully. Therefore, partial
allocation should not be treated as a fatal error.
Modify es58x_alloc_rx_urbs() to return 0 if at least one URB has been
allocated, restoring the intended behavior and preventing the leak
in es58x_open().
Severity ?
No CVSS data available.
