CVE-2024-57984: Linux Kernel

High severity, CVSS 7.8. EPSS: 0.2% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: i3c: dw: Fix use-after-free in dw_i3c_master driver due to race condition In dw_i3c_common_probe, &master->hj_work is bound with dw_i3c_hj_work. And dw_i3c_master_irq_handler can call dw_i3c_master_irq_handle_ibis function to start the work. If we remove the module which will call dw_i3c_common_remove to make cleanup, it will free master->base through i3c_master_unregister while the work mentioned above will be used. The sequence of operations that may lead to a UAF bug is as follows: CPU0 CPU1 | dw_i3c_hj_work dw_i3c_common_remove | i3c_master_unregister(&master->base) | device_unregister(&master->dev) | device_release | //free master->base | | i3c_master_do_daa(&master->base) | //use master->base Fix it by ensuring that the work is canceled before proceeding with the cleanup in dw_i3c_common_remove.

Affected products

• Linux Linux Kernel: from 5.0, before 6.6.76 (fixed in 6.6.76); from 6.7, before 6.12.13 (fixed in 6.12.13); from 6.13, before 6.13.2 (fixed in 6.13.2)
