CVE-2026-68385

A flaw was found in the Linux kernel's s390 architecture checksumming mechanism. On systems without a vector facility, the csumpartial function incorrectly calculates checksums. This occurs because the csumcopy function, when called with specific parameters, falls back to calculating the checksum...

CVE-2026-68385

In the Linux kernel, the following vulnerability has been resolved: s390/checksum: Fix csumpartial without vector facility Currently csumpartial calls csumcopy with copy=false and dst=NULL. On machines without the vector facility, csumcopy falls back to cksmdst, ..., causing the checksum to be...

CVE-2017-6347

The skbs processed by ipcmsgrecv are not guaranteed to be linear e.g. when sending UDP packets over loopback with MSGMORE. Using csumpartial on potentially the whole skb len is dangerous; instead be on the safe side and use skbchecksum. This may lead to an infoleak as the kernel memory may be...
