Vulnerability from github – Published: 2024-02-28 09:30 – Updated: 2024-12-09 21:31

Details

In the Linux kernel, the following vulnerability has been resolved:

Drivers: hv: vmbus: Use after free in __vmbus_open()

The "open_info" variable is added to the &vmbus_connection.chn_msg_list, but the error handling frees "open_info" without removing it from the list. This will result in a use after free. First remove it from the list, and then free it.

Severity ?

7.8 (High)
