"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nspeakup: keyhelp: guard letter_offsets possible out-of-range indexing\n\nhelp_init() builds letter_offsets[] by using the first byte of each\nfunction name as an index via `(start & 31) - 1`. If function_names are\noverridden from sysfs (root) with a name starting outside [a–z], the\nindex underflows or exceeds the array, leading to OOB write.\n\nFunction names can be overridden with the following commands as root:\n\n modprobe speakup_soft\n echo \"0 _bad\" > /sys/accessibility/speakup/i18n/function_names\n # then press Insert+2 on /dev/tty\n\nThis fix checks the first letter in help_init(), and if it is not in the\n[a–z] range the function returns an error to the caller. Eventually this\nerror is propagated to drivers/accessibility/speakup/main.c:2217, which\ncauses a bleep sound."
