medium Tenable Cloud Security Plugin ID 450594

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: bpf: Fix issue in verifying
allow_ptr_leaks After we converted the capabilities of our networking-bpf program from cap_sys_admin to
cap_net_admin+cap_bpf, our networking-bpf program failed to start. Because it failed the bpf verifier, and
the error log is "R3 pointer comparison prohibited". A simple reproducer as follows, SEC("cls-ingress")
int ingress(struct __sk_buff *skb) { struct iphdr *iph = (void *)(long)skb->data + sizeof(struct ethhdr);
if ((long)(iph + 1) > (long)skb->data_end) return TC_ACT_STOLEN; return TC_ACT_OK; } Per discussion with
Yonghong and Alexei [1], comparison of two packet pointers is not a pointer leak. This patch fixes it. Our
local kernel is 6.1.y and we expect this fix to be backported to 6.1.y, so stable is CCed. [1].
