CVE-2025-38180 Details
Description
In the Linux kernel, the following vulnerability has been resolved: net: atm: fix /proc/net/atm/lec handling /proc/net/atm/lec must ensure safety against dev_lec[] changes. It appears it had dev_put() calls without prior dev_hold(), leading to imbalance and UAF.
A use-after-free vulnerability has been identified in the Linux kernel's ATM (Asynchronous Transfer Mode) subsystem, specifically within the /proc/net/atm/lec interface. The issue arises from improper management of device references, where dev_put() calls were made without corresponding dev_hold() calls. This oversight created an imbalance in reference counting, leading to a use-after-free condition.
