  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: intel/ipu6: fix async notifier cleanup leak on parse error\n\nisys_notifier_init() calls v4l2_async_nf_init() and then adds fwnode\nremote subdevs in a loop with v4l2_async_nf_add_fwnode_remote(). If an\nendpoint parse or add fails partway through the loop, it jumps to\nerr_parse and returns without calling v4l2_async_nf_cleanup(), leaking\nevery v4l2_async_connection already added to the notifier's waiting\nlist.\n\nThe register-failure path just below already cleans up correctly, and\nthe caller only tears the notifier down (isys_notifier_cleanup()) once\nisys_notifier_init() has returned success. Clean up the notifier on the\nparse error path too.",
