      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: gadget: f_uac1_legacy: remove broken string configfs attributes\n\nThe UAC1_STR_ATTRIBUTE macro defines configfs show/store handlers for\nthe fn_play, fn_cap, and fn_cntl string options. The store function\ncontains an inverted null check on the kstrndup() return value.\n\nThis means every write attempt returns -ENOMEM on success and\ndereferences a NULL pointer on allocation failure. The attributes\nhave been broken and unused for many years.\n\nRemove the UAC1_STR_ATTRIBUTE macro and the three attributes it\ngenerated. The internal defaults (FILE_PCM_PLAYBACK, FILE_PCM_CAPTURE,\nFILE_CONTROL) set in f_audio_alloc_inst() are unaffected.",
