CVE-2022-50558

10
FAUCET Score

CVE-2022-50558 is a Linux kernel vulnerability that can lead to a null pointer dereference. This occurs because the regmap_add_irq_chip_fwnode function failed to properly utilize a new property (num_config_regs) for IRQ configuration, causing issues when older properties were removed in specific drivers like WCD9335. While no CVSS score is provided, the potential impact is a kernel crash, indicating a denial-of-service risk. There is no evidence of active exploitation, publicly available exploit code, or significant community discussion surrounding this vulnerability.
