CVE-2026-63939

CVE-2026-63939 (Linux kernel, KVM SEV): The issue concerns computation of the maximum length for the in-GHCB scratch area in the GHCB shared buffer. Previously, KVM assumed the input length (@len) always represented the maximum required size for MMIO emulation; for PSC requests, @len is only the ...

CVE-2026-63920

In the Linux kernel, the following vulnerability has been resolved: ipv6: validate extension header length before copying to cmsg ip6datagramrecvspecificctl builds IPV6HOPOPTS,DSTOPTS,RTHDR cmsgs and their IPV62292 legacy counterparts by trusting the on-wire hdrlen byte ptr1 when computing the...

CVE-2026-63920

The CVE-2026-63920 entry describes a Linux kernel vulnerability in IPv6 extension header handling. The issue arises when ip6_datagram_recv_specific_ctl() builds IPV6_…cmsgs by trusting on-wire hdrlen (ptr[1]) during put_cmsg() length calculation. Although the write to hdrlen is in-bounds, reading...
