Description
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.

CWE
KEV
| CWE ID | Description |
|---|---|
| CWE-416 | The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability in the Linux kernel involves improper handling of /proc/net/atm/lec. Specifically, the code had dev_put() calls without corresponding dev_hold() calls, causing an imbalance that could lead to use-after-free (UAF) issues related to dev_lec[] changes.
How can this vulnerability impact me? :
The vulnerability can lead to use-after-free conditions in the kernel, which may cause system instability, crashes, or potentially allow an attacker to execute arbitrary code or escalate privileges.
