Description OSIDB Bzimport 2026-01-13 16:07:52 UTC

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.
