CVE-2025-22058 is an integer-overflow vulnerability in Linux kernel UDP receive-memory accounting. During socket destruction, udp_destruct_common() sums queued packets' skb->truesize values into an unsigned integer and passes the total to udp_rmem_release(), which accepts a signed integer. A sufficiently large receive queue can therefore convert the total into a negative value, corrupting memory-release calculations and incorrectly increasing recorded UDP memory allocation. The erroneous accounting persists after socket closure and can cause subsequent UDP allocation failures and packet drops. Per-CPU memory accounting can defer the visible accounting increase until a subsequent UDP receive.

A Linux kernel UDP memory-accounting vulnerability triggered by integer overflow when releasing a socket's receive-buffer memory. Incorrect accounting can persist after socket closure and cause UDP packet drops, affecting availability. The reference assigns a CVSS v3 score of 5.5 and describes a local attack requiring privileges. It includes a reproduction script but explicitly reports that no known exploits are available.
A locally exploitable vulnerability requiring low privileges and no user interaction that can cause high availability impact, with no stated confidentiality or integrity impact.
