- Summary
- net: ethernet: mtk_wed: fix use-after-free panic in mtk_wed_setup_tc_block_cb()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: mtk_wed: fix use-after-free panic in mtk_wed_setup_tc_block_cb()
When there are multiple ap interfaces on one band and with WED on, turning the interface down will cause a kernel panic on MT798X.
Previously, cb_priv was freed in mtk_wed_setup_tc_block() without marking NULL,and mtk_wed_setup_tc_block_cb() didn't check the value, too.
Assign NULL after free cb_priv in mtk_wed_setup_tc_block() and check NULL in mtk_wed_setup_tc_block_cb().
