CVE ID :CVE-2026-43494<\/p>\n

Description :In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
net\/rds: reset op_nents when zerocopy page pin fails<\/p>\n
When iov_iter_get_pages2() fails in rds_message_zcopy_from_user(),
\nthe pinned pages are released with put_page(), and
\nrm->data.op_mmp_znotifier is cleared. But we fail to properly
\nclear rm->data.op_nents.<\/p>\n
Later when rds_message_purge() is called from rds_sendmsg() the
\ncleanup loop iterates over the incorrectly non zero number of
\nop_nents and frees them again.<\/p>\n
Fix this by properly resetting op_nents when it should be in
\nrds_message_zcopy_from_user().<\/p>\n
Severity: 0.0 | NA<\/p>\n
