CVE-2026-89648

CVE-2026-89648 affects the Linux kernel Ceph client in the function ceph_parse_deleg_inos(). When decoding delegated-inode intervals from an MDS create-with-delegation reply, the 64-bit len field is fully attacker-controlled and was previously unbounded. A malicious or compromised Ceph MDS can se...

CVE-2026-89563

CVE-2026-89563 is a double-free vulnerability in the Linux kernel's ip6_tunnel module. The ip6_tnl_xmit() function uses skb_realloc_headroom() to expand headroom before pushing outer IPv6 and optional encap headers, consuming the original socket buffer (skb) and keeping the replacement only in a ...

CVE-2026-89537

CVE-2026-89537 affects the Linux kernel's SUNRPC subsystem, specifically the gss_krb5_verify_mic_v2() function, which reads RFC 4121 MIC token header fields without first validating the token length. A remote malicious NFS server can supply an undersized Kerberos MIC token, causing the verifier t...
