kernel: bpf, sockmap: Fix repeated calls to sock_put() when msg has more_data

A reference-count flaw was found in the Linux kernel Berkeley Packet Filter BPF sockmap implementation. When processing messages with remaining data, the same Transmission Control Protocol TCP socket reference could be released more than once. A local user running BPF sockmap programs could use...

kernel: Local privilege escalation due to incorrect BPF JIT branch displacement computation

A flaw was found in the Linux kernels eBPF implementation. By default, accessing the eBPF verifier is only accessible to privileged users with CAPSYSADMIN. A local user with the ability to insert eBPF instructions can abuse a flaw in eBPF to corrupt memory. The highest threat from this...
