Summary

The Linux kernel drm/xe/i2c driver is affected from 6.19. During unbind, struct xe_i2c is freed before the SGUnit IRQ is disabled, so an I2C interrupt that arrives in that short window can use freed memory.

Description from the CNA

In the Linux kernel, the following vulnerability has been resolved: drm/xe/i2c: Disable IRQ on unbind Currently, struct xe_i2c is freed before SGUnit IRQ is disabled in unbind path, leaving a potential UAF in case I2C IRQ is hit during this small window. Explicitly disable I2C IRQ in xe_i2c_remove() and fix this. (cherry picked from commit 8ba5c8b8ab3fd362267c11df2cd5a90ee46f6e24)
