VulnCheck KEV: CVE-2026-43494

In the Linux kernel, the following vulnerability has been resolved: net/rds: reset opnents when zerocopy page pin fails When iovitergetpages2 fails in rdsmessagezcopyfromuser, the pinned pages are released with putpage, and rm-data.opmmpznotifier is cleared. But we fail to properly clear...

CVE-2026-74627

A flaw was found in the Linux kernel's net: devmem component. This vulnerability occurs when netiov and page-backed fragments are improperly mixed within a single skb socket buffer in the zerocopyfillskbfromdevmem function. This improper handling can lead to a system crash, resulting in a Denial ...
