  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nhost1x: bus: Fix missing ops null check in error teardown\n\nIn host1x_device_init(), the error teardown paths do not check\nclient->ops before dereferencing it, unlike the forward init paths\nwhich correctly guard with 'client->ops &&'. This can result in a\nNULL pointer dereference if client->ops is NULL.\n\nFix by adding the missing client->ops check in both the teardown\nand teardown_late labels.",
