kernel: Linux kernel: smb: client: reject userspace cifs.spnego descriptions

A privilege escalation vulnerability was found in the Linux kernel's CIFS client implementation. This could allow a local attacker to impersonate other users, bypass authentication in SMB mount operations, and potentially gain unauthorized access to network file shares or escalate privileges...

kernel: ip6_tunnel: clear skb2->cb[] in ip4ip6_err()

A flaw was found in the Linux kernel's IPv6 tunnel implementation. A remote attacker could exploit this flaw by sending malicious ICMPv6 error messages to cause a stack-based buffer overflow in the kernel's IPv4-over-IPv6 tunnel error handling code. This could result in a kernel crash denial of...
