{"apiVersion":"1.0","identifier":"CVE-2026-74379","description":"In the Linux kernel, the following vulnerability has been resolved: dax/kmem: account for partial discontiguous resource upon removal When dev_dax_kmem_probe() partially succeeds (at least one range is mapped) but a subsequent range fails request_mem_region() or add_memory_driver_managed(), the probe silently continues, ultimately returning success, but with the corresponding range resource NULL-ed out. dev_dax_kmem_remove() iterates over all dax_device ranges regardless of if the underlying resource exists. When remove_memory() is called later, it returns 0 because the memory was never added which causes dev_dax_kmem_remove() to incorrectly assume the (nonexistent) resource can be removed and attempts cleanup on a NULL pointer. Fix this by skipping these ranges altogether, noting that these cases are considered success, such that the cleanup is still reached when all actually-added ranges are successfully removed.","publishedAt":"2026-08-15T06:22:39","lastModifiedAt":"2026-08-17T06:19:32","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74379","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00173,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74379","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74379","en":"https://www.redsauce.net/en/cves/CVE-2026-74379","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74379","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74379","de":"https://www.redsauce.net/de/cves/CVE-2026-74379","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74379","el":"https://www.redsauce.net/el/cves/CVE-2026-74379"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74379"}}
