CVE-2026-23037

Description

In the Linux kernel, the following vulnerability has been resolved:can: etas_es58x: allow partial RX URB allocation to succeedWhen es58x_alloc_rx_urbs() fails to allocate the requested number ofURBs but succeeds in allocating some, it returns an error code.This causes es58x_open() to return early, skipping the cleanup labelfree_urbs, which leads to the anchored URBs being leaked.As pointed out by maintainer Vincent Mailhol, the driver is designedto handle partial URB allocation gracefully. Therefore, partialallocation should not be treated as a fatal error.Modify es58x_alloc_rx_urbs() to return 0 if at least one URB has beenallocated, restoring the intended behavior and preventing the leakin es58x_open().
