DEBIAN-CVE-2023-52763
No affected components available
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 DAT init. Additionally, if the i3c_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.
The vulnerability requires local access to the device to be exploited. It is easy for an attacker to exploit this vulnerability. An attacker needs basic access or low-level privileges. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a high impact on the availability of the system.
Exploitation attempts have been detected. Elevated vigilance and prompt remediation are advised.
