"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ngpio: cdev: fix kernel stack leak to user-space in error path\n\nIf we fail to acquire the GPIO chip guard in gpio_desc_to_lineinfo(), we\nreturn immediately before zeroing the info struct we'll end up passing\nto the user-space later in lineinfo_get_v1(). This may leak the kernel\nstack contents. Make gpio_desc_to_lineinfo() return int so that the\n-ENODEV returned on failure to acquire the guard can be propagated to\nthe callers.\n\nWhile not strictly necessary: move the memset() before trying to acquire\nthe SRCU read lock too for good measure."
