CVE-2025-38485

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> iio: accel: fxls8962af: Fix use after free in fxls8962af_fifo_flush<br /> <br /> fxls8962af_fifo_flush() uses indio_dev-&gt;active_scan_mask (with<br /> iio_for_each_active_channel()) without making sure the indio_dev<br /> stays in buffer mode.<br /> There is a race if indio_dev exits buffer mode in the middle of the<br /> interrupt that flushes the fifo. Fix this by calling<br /> synchronize_irq() to ensure that no interrupt is currently running when<br /> disabling buffer mode.<br /> <br /> Unable to handle kernel NULL pointer dereference at virtual address 00000000 when read<br /> [...]<br /> _find_first_bit_le from fxls8962af_fifo_flush+0x17c/0x290<br /> fxls8962af_fifo_flush from fxls8962af_interrupt+0x80/0x178<br /> fxls8962af_interrupt from irq_thread_fn+0x1c/0x7c<br /> irq_thread_fn from irq_thread+0x110/0x1f4<br /> irq_thread from kthread+0xe0/0xfc<br /> kthread from ret_from_fork+0x14/0x2c
