CVE-2025-38485

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

iio: accel: fxls8962af: Fix use after free in fxls8962affifoflush

fxls8962affifoflush() uses indiodev->activescanmask (with iioforeachactivechannel()) without making sure the indiodev stays in buffer mode. There is a race if indiodev exits buffer mode in the middle of the interrupt that flushes the fifo. Fix this by calling synchronizeirq() to ensure that no interrupt is currently running when disabling buffer mode.
