CVE-2024-46677

Severity:
MEDIUM
Type:
CWE-476 NULL Pointer Dereference
Publication date:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> gtp: fix a potential NULL pointer dereference<br /> <br /> When sockfd_lookup() fails, gtp_encap_enable_socket() returns a<br /> NULL pointer, but its callers only check for error pointers thus miss<br /> the NULL pointer case.<br /> <br /> Fix it by returning an error pointer with the error code carried from<br /> sockfd_lookup().<br /> <br /> (I found this bug during code inspection.)
