CVE-2025-68811: svcrdma: use rc_pageoff for memcpy byte offset

Noroxi assessment

Priority: Monitor (action score 39/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.53% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 2a77c8dd49bccf0ca232be7c836cec1209abb8da, a8ee9099f30654917aa68f55d707b5627e1dbf77, e8623e9c451e23d84b870811f42fd872b4089ef6.

Low priority for now. Upgrade to Linux Linux 2a77c8dd49bccf0ca232be7c836cec1209abb8da, a8ee9099f30654917aa68f55d707b5627e1dbf77, e8623e9c451e23d84b870811f42fd872b4089ef6 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: svcrdma: use rc_pageoff for memcpy byte offset svc_rdma_copy_inline_range added rc_curpage (page index) to the page base instead of the byte offset rc_pageoff. Use rc_pageoff so copies land within the current page. Found by ZeroPath (https://zeropath.com)
