Vulnerability from github – Published: 2024-05-21 18:31 – Updated: 2025-09-19 15:31

Details

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

i3c: master: mipi-i3c-hci: Fix a kernel panic for accessing DAT_data.

The i3c_master_bus_init function may attach the I2C devices before the I3C bus initialization. In this flow, the DAT alloc_entry`` will be used before the DATinit. Additionally, if thei3c_master_bus_initfails, the DATcleanupwill execute before the device is detached, which will execue DATfree_entry` function. The above scenario can cause the driver to use DAT_data when it is NULL.

Severity ?

5.5 (Medium)
