A flaw was found in the Linux kernel, where an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack. This issue occurs when the protection mechanism neglects the possibility of uninitialized memory locations on the BPF stack. The highest threat from this vulnerability is to confidentiality. A flaw in the Linux kernel allows a privileged BPF program to obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel in the eBPF subsystem A vulnerability was found in the Linux kernel. Missing size validations on inbound SCTP packets may allow the kernel to read uninitialized memory
