CVE-2022-50840 is a vulnerability of currently unknown severity. In the Linux kernel, the following vulnerability has been resolved: scsi: snic: Fix possible UAF in snic_tgt_create() Smatch reports a warning as follows: drivers/scsi/snic/snic_disc.c:307 snic_tgt_create() warn: '&tgt->list' not removed from list If device_add() fails in snic_tgt_create(), tgt will be freed, but tgt->list will not be removed from snic->disc.tgt_list, then list traversal may cause UAF. Remove from snic->disc.tgt_list before free().. EPSS estimates a 0.24% chance of exploitation in the next 30 days.
