Overview
CVE-2026-68135 is a known-severity vulnerability. It was published on August 10, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
net: hip04: fix RX buffer leak on build_skb failure
When build_skb() fails in hip04_rx_poll(), the driver jumps to the
refill path without releasing the current RX buffer and its DMA mapping.
Installing a replacement buffer then overwrites the slot references and
leaks both resources.
Keep the current slot intact and return budget so NAPI retries the same
buffer. Also free a newly allocated RX fragment when dma_map_single()
fails.
This issue was found by an in-house static analysis tool.
Remediation

How can CyberStrike help with CVE-2026-68135?
CyberStrike is an open-source, AI-augmented pentesting engine.
