| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 5.15.0-1036-bluefield
Description
The vulnerability is related to the mlxbf gige driver in the Linux kernel. When kdump is enabled, the driver encounters a NULL pointer exception in the
mlxbf gige open() function. This happens because there is a pending RX interrupt before the call to request irq(RX IRQ) executes, and the RX IRQ handler fires immediately after this request irq() completes. The issue can be reproduced by enabling kdump, triggering kdump via /proc/sysrq-trigger, and loading the mlxbf gige module.Recommendations
To resolve the issue, update the Linux kernel to version 5.15.0-1036-bluefield or later. If an update is not available, consider disabling the
mlxbf gige driver or the kdump feature as a temporary workaround to prevent the NULL pointer exception.Exploit
