CVE-2025-38056 is fixed in 36 products on 1 platform, first by DEBIAN-CVE-2025-38056, released June 18, 2025. It is not reported as exploited. Patch Radar priority: High. - Web page: https://patchblox.com/security/cve/CVE-2025-38056 - Priority: High - CVSS: 7.8 (high) - EPSS: 0.0020 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Jun 18, 2025 ## Description In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: Intel: hda: Fix UAF when reloading module hda_generic_machine_select() appends -idisp to the tplg filename by allocating a new string with devm_kasprintf(), then stores the string right back into the global variable snd_soc_acpi_intel_hda_machines. When the module is unloaded, this memory is freed, resulting in a global variable pointing to freed memory. Reloading the module then triggers a use-after-free: BUG: KFENCE: use-after-free read in string+0x48/0xe0 Use-after-free read at 0x00000000967e0109 (in kfence-#99): string+0x48/0xe0
