CVE-2026-64177

CVE-2026-64177 is a Linux kernel vulnerability in the Phonet protocol (pep) handling where forwarding of skb to a child socket via sk_receive_skb() incorrectly acquires the child socket lock with BH enabled in the softirq path. The root cause is a BH state mismatch between softirq and process pat...

CVE-2026-64177

In the Linux kernel, the following vulnerability has been resolved: phonet/pep: disable BH around forwarded skreceiveskb The networking receive path is usually run from softirq context, but protocols that take the socket lock may have packets stored in the backlog and processed later from process...
