Description

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

Affected configurations

• linux linux kernel (>= 4.12 < 4.19.321) • linux linux kernel (>= 4.20 < 5.4.283) • linux linux kernel (>= 5.5 < 5.10.225) • linux linux kernel (>= 5.11 < 5.15.166) • linux linux kernel (>= 5.16 < 6.1.108) • linux linux kernel (>= 6.2 < 6.6.49) • linux linux kernel (>= 6.7 < 6.10.8) • linux linux kernel 6.11
