{"apiVersion":"1.0","identifier":"CVE-2026-74459","description":"In the Linux kernel, the following vulnerability has been resolved: can: etas_es58x: es58x_read_bulk_callback(): fix RX buffer leak on URB resubmit failure es58x_read_bulk_callback() resubmits the RX URB after processing a received packet. If the resubmit succeeds, the URB remains anchored and will be handled by the normal RX path or by teardown. However, if usb_submit_urb() fails, the callback unanchors the URB and then returns directly. This skips the existing free_urb path, so the coherent transfer buffer allocated with usb_alloc_coherent() is not released. Reuse the existing free_urb path after a resubmit failure so that the RX coherent buffer is freed before leaving the callback.","publishedAt":"2026-08-15T13:17:50","lastModifiedAt":"2026-08-19T17:21:02","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74459","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-2026-74459","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74459","en":"https://www.redsauce.net/en/cves/CVE-2026-74459","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74459","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74459","de":"https://www.redsauce.net/de/cves/CVE-2026-74459","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74459","el":"https://www.redsauce.net/el/cves/CVE-2026-74459"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74459"}}
