Linux · Linux Kernel · CVE-2022-49273
**Name of the Vulnerable Software and Affected Versions**
Linux kernel (affected versions not specified)
**Description**
A null pointer dereference issue was found in the Linux kernel, specifically in the `pl031` Real-Time Clock (RTC) driver. The issue occurs when there is no interrupt line and the RTC alarm feature is disabled. The clearing of the `RTC FEATURE ALARM` bit was being done before the allocation of the `ldata->rtc` device, resulting in a null pointer dereference. The fix involves clearing the `RTC FEATURE ALARM` bit after the RTC device is allocated.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
