Vulnerability from github – Published: 2026-01-13 18:31 – Updated: 2026-07-30 06:32

Details

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)

Severity

9.8 (Critical)
