"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: sg: Resolve soft lockup issue when opening /dev/sgX\n\nThe parameter def_reserved_size defines the default buffer size reserved\nfor each Sg_fd and should be restricted to a range between 0 and 1,048,576\n(see https://tldp.org/HOWTO/SCSI-Generic-HOWTO/proc.html). Although the\nfunction sg_proc_write_dressz enforces this limit, it is possible to bypass\nit by directly modifying the module parameter as shown below, which then\ncauses a soft lockup:\n\necho -1 > /sys/module/sg/parameters/def_reserved_size\nexec 4<> /dev/sg0\n\nwatchdog: BUG: soft lockup - CPU#5 stuck for 26 seconds!
