Consequently, error paths triggered after\nsuccessfully parsing the EEPROM free priv->nvm_data but leak\npriv->eeprom_blob.\n\nFix this memory leak by reordering the error handling labels so\nthat out_free_eeprom falls through to out_free_eeprom_blob.\n\nThe bug was first flagged by an experimental analysis tool we are\ndeveloping for kernel memory-management bugs while analyzing\nv6.13-rc1. The tool is still under development and is not yet publicly\navailable. Manual inspection confirms that the bug is still\npresent in v7.1-rc6.\n\nAn x86_64 allyesconfig build showed no new warnings. As we do not have\nsupported Intel DVM wireless hardware and firmware to test with, no\nruntime testing was able to be performed.\n\n## Affected\n\n- `Linux >= 26a7ca9a71a3f7e1826de96b1a1e907123e11b07 < 7be73911d979bb0f54485c2292043a5703fdc953`\n- `Linux >= 26a7ca9a71a3f7e1826de96b1a1e907123e11b07 < 2d593f32efa9ff1c91c508f45eb709c03dfb4945`\n- `Linux >= 26a7ca9a71a3f7e1826de96b1a1e907123e11b07 < 84ba017a1e1ea7896ed1e3258c947bdbfc5299c5`\n- `Linux >= 26a7ca9a71a3f7e1826de96b1a1e907123e11b07 < ad2a9fdca4a7100472be82ee6048c616fc589720`\n- `Linux >= 26a7ca9a71a3f7e1826de96b1a1e907123e11b07 < 67105abd6195a685a84dcb8a5daf54a1f4bfdb60`\n- `Linux 3.6`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Low · affected: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, Red Hat OpenShift Container Platform 4 · no fix planned: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, … · updated 2026-09-14 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-80948.json)","depth":"sunlit","depthScore":30,"depthScoreParts":{"impact":30.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":204248,"id":"CVE-2026-80948","ts":1789490240611,"field":"cvss","old":null,"new":"5.5"},{"seq":204247,"id":"CVE-2026-80948","ts":1789490240611,"field":"severity","old":"none","new":"medium"},{"seq":147510,"id":"CVE-2026-80948","ts":1789270211191,"field":"cvss","old":null,"new":"4.7"},{"seq":147509,"id":"CVE-2026-80948","ts":1789270211191,"field":"severity","old":"none","new":"medium"},{"seq":109262,"id":"CVE-2026-80948","ts":1789183731190,"field":"cvss","old":null,"new":"4.7"},{"seq":109261,"id":"CVE-2026-80948","ts":1789183731190,"field":"severity","old":"none","new":"medium"}]}
