CVE-2026-63984

CVE-2026-63984 affects the Linux kernel, addressing an overflow in the IPv6 RPL SRH decompression path. The bug occurs in ipv6_rpl_srh_decompress(): hdrlen is computed as outhdr->hdrlen = (((n + 1) * sizeof(struct in6_addr)) >> 3); since hdrlen is an 8-bit value, for n >= 127 the resu...

In the Linux kernel, the following vulnerability has been resolved: KVM: SEV: Ignore Port I/O requests of length '0' Explicitly ignore Port I/O requests of length '0' or count '0', so that setting up the software scratch area and other code doesn't have to worry about underflowing the length, and...

CVE-2026-63940 KVM: SEV: Ignore Port I/O requests of length '0'

In the Linux kernel, the following vulnerability has been resolved: KVM: SEV: Ignore Port I/O requests of length '0' Explicitly ignore Port I/O requests of length '0' or count '0', so that setting up the software scratch area and other code doesn't have to worry about underflowing the length, and...

CVE-2026-63940

In the Linux kernel KVM SEV issue, the vulnerability concerns ignoring Port I/O requests of length 0. The fix ensures that Port I/O requests with length 0 (or count 0) are explicitly ignored so that the software scratch area setup and related code won’t underflow the length, and to enable a warni...
