[REJECTED CVE] In the Linux kernel, the following vulnerability has been resolved: mwifiex: fix sleep in atomic context bugs caused by dev_coredumpv
In the Linux kernel, the following vulnerability has been resolved: mwifiex: fix sleep in atomic context bugs caused by dev_coredumpv There are sleep in atomic context bugs when uploading device dump data in mwifiex. The root cause is that dev_coredumpv could not be used in atomic contexts, because it calls dev_set_name which include operations that may sleep. The call tree shows execution paths that could lead to bugs: (Interrupt context) fw_dump_timer_fn mwifiex_upload_device_dump dev_coredumpv(..., GFP_KERNEL) dev_coredumpm() kzalloc(sizeof(*devcd), gfp); //may sleep dev_set_name kobject_set_name_vargs kvasprintf_const(GFP_KERNEL, ...); //may sleep kstrdup(s, GFP_KERNEL); //may sleep The corresponding fail log is shown below: [ 135.275938] usb 1-1: == mwifiex dump information to /sys/class/devcoredump start [ 135.281029] BUG: sleeping function called from invalid context at include/linux/sched/mm.h:265 ...
