CVE-2024-26872

Severity CVSS v4.0:
Pending analysis
Type:
CWE-416 Use After Free

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> RDMA/srpt: Do not register event handler until srpt device is fully setup<br /> <br /> Upon rare occasions, KASAN reports a use-after-free Write<br /> in srpt_refresh_port().<br /> <br /> This seems to be because an event handler is registered before the<br /> srpt device is fully setup and a race condition upon error may leave a<br /> partially setup event handler in place.<br /> <br /> Instead, only register the event handler after srpt device initialization<br /> is complete.
