{"apiVersion":"1.0","identifier":"CVE-2026-72394","description":"In the Linux kernel, the following vulnerability has been resolved: hwmon: (aspeed-g6-pwm-tach) Guard fan RPM calculation against divide-by-zero Sashiko reports: In the aspeed-g6-pwm-tacho driver, the aspeed_tach_val_to_rpm() function calculates the fan RPM using the tachometer value. However, it does not check if the tachometer value is zero before performing the division. If the hardware reports a tachometer value of 0 (which can happen due to an extremely fast pulse, a stuck edge, or a hardware glitch), the calculated tach_div evaluates to 0. The subsequent call to do_div() with tach_div as the divisor triggers a divide-by-zero exception, leading to a kernel panic. Check the divisor against zero to fix the problem.","publishedAt":"2026-08-15T06:22:12","lastModifiedAt":"2026-08-17T06:19:05","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72394","cvssScore":null,"cvssVector":"Pending","epssProbability":0.002,"riskScore":0,"affectedProduct":"linux","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72394","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72394","en":"https://www.redsauce.net/en/cves/CVE-2026-72394","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72394","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72394","de":"https://www.redsauce.net/de/cves/CVE-2026-72394","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72394","el":"https://www.redsauce.net/el/cves/CVE-2026-72394"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72394"}}
