USN-8930-2CVE-2026-74220CVE-2026-74221CVE-2026-74222CVE-2026-74225U-Boot vulnerabilities Executive summary Canonical's USN-8930-2 covers several security flaws in U-Boot, the boot loader used on embedded systems, for Ubuntu 26.10. The advisory says the flaws could allow denial of service and, in one case, possibly arbitrary code execution, and it recommends updating to the fixed package versions listed. The advisory does not state a severity rating. Technical summary The advisory describes improper handling of NFS READ and NFS READLINK responses that could cause a buffer overflow (CVE-2026-74220, CVE-2026-74221), which may lead to denial of service or arbitrary code execution. It also describes a use-after-free in the lwIP implementation triggered by HTTP data storage failures (CVE-2026-74222), and out-of-bounds memory access from improperly validated DHCPv6 option lengths during network boot (CVE-2026-74225). The advisory states the fixed package version as 2025.10-0ubuntu6 for u-boot-imx, u-boot-qemu, and u-boot-tools on 26.10. Attack preconditions, workarounds, and detection guidance are not stated. Summaries are generated by AI from the linked advisory text. Confirm versions and fixes at the source.
