A flaw was found in the Linux kernel. This issue occurs in the BPF subsystem when loading BPF_PROG_TYPE_EXT
programs without specifying attr->attach_prog_fd
, causing a null pointer dereference in resolve_prog_type()
. The issue was introduced in a commit that incorrectly resolved program types without checking if dst_prog
was null.
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
