RUSTSEC-2026-0220 Uint shift operations: incorrect overflow flags and truncated shift amounts

Uint::overflowingshl/overflowingshr returned false-negative overflow flags. overflowingshl missed bits shifted above BITS but within the top limb non-limb-aligned widths such as U160, and limbs wholly discarded by shifts = 64; overflowingshr missed wholly discarded low limbs. Shifted values were...

OR1200 Authorization Issue Vulnerability

OR1200 is an OpenRISC 1200 implementation of the OpenRISC open source. A security vulnerability exists in OR1200 that stems from the ALU unit not updating the overflow flags for the msb and mac instructions, resulting in incorrect values in the overflow flags...
