The Cost of Restaking Vs. Proof-Of-Stake

We compare the efficiency of restaking and Proof-of-Stake PoS protocols in terms of stake requirements. First, we consider the sufficient condition for the restaking graph to be secure. We show that the condition implies that it is always possible to transform such a restaking graph into secure P...

Buffer overflow due to lack of upper bound check on channel length which is used for a loop. in Snapdragon Compute, Snapdragon Connectivity, Snapdragon Consumer Electronics Connectivity, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Wired Infrastructure and...

kernel: ipv4: ip_tunnel: Fix suspicious RCU usage warning in ip_tunnel_init_flow()

A flaw was found in the Linux kernel's IPv4 tunneling subsystem. Certain code paths during tunnel initialization traverse network device lists without holding the required Read-Copy-Update RCU read lock. A local user could exploit this flaw while configuring network interfaces, potentially leadin...

USN-7505-1 abseil vulnerability

It was discovered that Abseil incorrectly handled memory with the upper bound of the size argument. An attacker could possibly use this issue to cause a denial of service or memory corruption...

New Capacity Bounds for PIR on Graph and Multigraph-Based Replicated Storage

In this paper, we study the problem of private information retrieval PIR in both graph-based and multigraph-based replication systems, where each file is stored on exactly two servers, and any pair of servers shares at most $r$ files. We derive upper bounds on the PIR capacity for such systems an...
