Patch Radar priority: Routine. - Web page: https://patchblox.com/security/cve/CVE-2026-58471 - Priority: Routine - CVSS: 6.5 (moderate) - EPSS: 0.0039 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Jul 7, 2026 ## Description GNU Wget through 1.25.0, fixed in commit c2640fe, contains a heap buffer overflow vulnerability in the convert_fname() function within src/url.c that allows remote attackers to trigger memory corruption through a server-supplied filename requiring character set conversion. When the output buffer is too small during iconv E2BIG reallocation, the reallocation logic miscalculates the remaining space, leading to a heap buffer overflow that can be exploited via a maliciously crafted server response. ## Where it's fixed | Platform | Product | Fixed in | Fix | Released | |---|---|---|---|---| | Linux | wget RHEL 10 | 1.24.5-8.el10_2 | [RHSA-2026:62142](https://patchblox.com/security/data/fix/linux/rhsa-2026-62142.md) | Jul 7, 2026 | | Linux | wget RHEL 8 | 0:1.19.5-16.el8_10 | [RHSA-2026:62144](https://patchblox.com/security/data/fix/linux/rhsa-2026-62144.md) | Sep 13, 2026 | | Linux | wget RHEL 9 | 0:1.21.1-11.el9_8 | [RHSA-2026:62143](https://patchblox.com/security/data/fix/linux/rhsa-2026-62143.md) | Sep 13, 2026 | | Linux | wget Ubuntu 18.04.6 LTS (bionic) | 1.19.4-1ubuntu2.2+esm3 | [wget 1.19.4-1ubuntu2.2+esm3](https://patchblox.com/security/data/fix/linux/ubuntu-bionic-wget-1.19.4-1ubuntu2.2-esm3.md) | Jul 18, 2026 | | Linux | wget Ubuntu 20.04 LTS (focal) | 1.20.3-1ubuntu2.1+esm2 | [wget 1.20.3-1ubuntu2.1+esm2](https://patchblox.com/security/data/fix/linux/ubuntu-focal-wget-1.20.3-1ubuntu2.1-esm2.md) | Jul 18, 2026 | | Linux | wget Ubuntu 22.04.1 LTS (jammy) | 1.21.2-2ubuntu1.3 | [wget 1.21.2-2ubuntu1.3](https://patchblox.com/security/data/fix/linux/ubuntu-jammy-wget-1.21.2-2ubuntu1.3.md) | Jul 18, 2026 | | Linux | wget Ubuntu 24.04.5 LTS (noble) | 1.21.4-1ubuntu4.3 | [wget 1.21.4-1ubuntu4.3](https://patchblox.com/security/data/fix/linux/ubuntu-noble-wget-1.21.4-1ubuntu4.3.md) | Jul 18, 2026 | | Linux | wget Ubuntu 26.04.1 LTS (resolute) | 1.25.0-2ubuntu4.2 | [wget 1.25.0-2ubuntu4.2](https://patchblox.com/security/data/fix/linux/ubuntu-resolute-wget-1.25.0-2ubuntu4.2.md) | Jul 7, 2026 | | Linux | wget almalinux 10 | 1.24.5-8.el10_2 | [ALSA-2026:62142](https://patchblox.com/security/data/fix/linux/alsa-2026-62142.md) | Sep 1, 2026 | | Linux | wget almalinux 8 | 1.19.5-16.el8_10 | [ALSA-2026:62144](https://patchblox.com/security/data/fix/linux/alsa-2026-62144.md) | Sep 1, 2026 | | Linux | wget almalinux 9 | 1.21.1-11.el9_8 | [ALSA-2026:62143](https://patchblox.com/security/data/fix/linux/alsa-2026-62143.md) | Sep 1, 2026 | | Linux | wget ol 10 | 0:1.24.5-8.el10_2 | [ELSA-2026-62142-0](https://patchblox.com/security/data/fix/linux/elsa-2026-62142-0.md) | Sep 1, 2026 | | Linux | wget ol 8 | 0:1.19.5-16.0.1.el8_10 | [ELSA-2026-62144-0](https://patchblox.com/security/data/fix/linux/elsa-2026-62144-0.md) | Sep 3, 2026 | | Linux | wget ol 9 | 0:1.21.1-11.el9_8 | [ELSA-2026-62143-0](https://patchblox.com/security/data/fix/linux/elsa-2026-62143-0.md) | Sep 1, 2026 | | Linux | wget opensuse-leap 16.0 | 1.25.0-160000.3.1 | [OPENSUSE-SU-2026:21665-1](https://patchblox.com/security/data/fix/linux/opensuse-su-2026-21665-1.md) | Aug 27, 2026 | | Linux | wget rocky 10 | 0:1.24.5-8.el10_2 | [RLSA-2026:62142](https://patchblox.com/security/data/fix/linux/rlsa-2026-62142.md) | Sep 2, 2026 | | Linux | wget rocky 8 | 0:1.19.5-16.el8_10 | [RLSA-2026:62144](https://patchblox.com/security/data/fix/linux/rlsa-2026-62144.md) | Sep 2, 2026 | | Linux | wget rocky 9 | 0:1.21.1-11.el9_8 | [RLSA-2026:62143](https://patchblox.com/security/data/fix/linux/rlsa-2026-62143.md) | Sep 2, 2026 | | Linux | wget sles 15.7 | 1.24.5-150700.3.3.1 | [SUSE-SU-2026:3148-1](https://patchblox.com/security/data/fix/linux/suse-su-2026-3148-1.md) | Jul 21, 2026 | | Linux | wget sles 16.0 | 1.25.0-160000.3.1 | [SUSE-SU-2026:23326-1](https://patchblox.com/security/data/fix/linux/suse-su-2026-23326-1.md) | Aug 27, 2026 | | Linux | wget1 Fedora 43 | 1.25.0-3.fc43 | [FEDORA-2026-7BBB52B49D](https://patchblox.com/security/data/fix/linux/fedora-2026-7bbb52b49d.md) | Jul 16, 2026 | | Linux | wget1-debuginfo Fedora 43 | 1.25.0-3.fc43 | [FEDORA-2026-7BBB52B49D](https://patchblox.com/security/data/fix/linux/fedora-2026-7bbb52b49d.md) | Jul 16, 2026 | | Linux | wget1-debugsource Fedora 43 | 1.25.0-3.fc43 | [FEDORA-2026-7BBB52B49D](https://patchblox.com/security/data/fix/linux/fedora-2026-7bbb52b49d.md) | Jul 16, 2026 | | Linux | wget1-wget Fedora 43 | 1.25.0-3.fc43 | [FEDORA-2026-7BBB52B49D](https://patchblox.com/security/data/fix/linux/fedora-2026-7bbb52b49d.md) | Jul 16, 2026 | --- Data as of 2026-11-09T01:18:40Z UTC.
