Summary
CVE-2024-49981 affecting package kernel for versions less than 5.15.173.1-1
Details

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

media: venus: fix use after free bug in venus_remove due to race condition

in venusprobe, core->work is bound with venussyserrorhandler, which is used to handle error. The code use core->syserrdone to make sync work. The core->work is started in venuseventnotify.

If we call venus_remove, there might be an unfished work. The possible sequence is as follows:

CPU0 CPU1

                 |venus_sys_error_handler

venusremove | hfidestroy | venushfidestroy | kfree(hdev); | |hfireinit |venushfiqueuesreinit |//use hdev

Fix it by canceling the work in venus_remove.
