Summary
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)
