CVE-2021-47239 (GCVE-0-2021-47239)

Vulnerability from cvelistv5 – Published: 2024-05-21 14:19 – Updated: 2025-05-04 07:06

Title

net: usb: fix possible use-after-free in smsc75xx_bind

Summary

In the Linux kernel, the following vulnerability has been resolved: net: usb: fix possible use-after-free in smsc75xx_bind The commit 46a8b29c6306 ("net: usb: fix memory leak in smsc75xx_bind") fails to clean up the work scheduled in smsc75xx_reset-> smsc75xx_set_multicast, which leads to use-after-free if the work is scheduled to start after the deallocation. In addition, this patch also removes a dangling pointer - dev->data[0]. This patch calls cancel_work_sync to cancel the scheduled work and set the dangling pointer to NULL.

Severity ?
