  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\niio: imu: adis: Fix NULL pointer dereference in adis_init\n\nThe adis_init() function dereferences adis-\u003eops to check if the\nindividual function pointers (write, read, reset) are NULL, but does\nnot first check if adis-\u003eops itself is NULL.\n\nDrivers like adis16480, adis16490, adis16545 and others do not set\ncustom ops and rely on adis_init() assigning the defaults. Since struct\nadis is zero-initialized by devm_iio_device_alloc(), adis-\u003eops is NULL\nwhen adis_init() is called, causing a NULL pointer dereference:\n\n    Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000\n    pc : adis_init+0xc0/0x118\n    Call trace:\n     adis_init+0xc0/0x118\n     adis16480_probe+0xe0/0x670\n\nFix this by checking if adis-\u003eops is NULL before dereferencing it,\nfalling through to assign the default ops in that case.",
