Vulnerability from fkie_nvd - Published: 2026-01-13 16:16 - Updated: 2026-07-30 06:24
Severity
9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
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)
