{"apiVersion":"1.0","identifier":"CVE-2026-74410","description":"In the Linux kernel, the following vulnerability has been resolved: wifi: rtw88: fix OOB read from firmware RX descriptor exceeding DMA buffer In rtw_pci_rx_napi(), new_len is computed as the sum of pkt_len (14-bit descriptor field, max 16383) and pkt_offset (drv_info_sz + shift, both firmware-controlled). The result can exceed RTK_PCI_RX_BUF_SIZE (11478), causing an out-of-bounds read from the pre-allocated DMA buffer when skb_put_data copies new_len bytes. The USB transport already validates this (rtw_usb_rx_data_put checks against RTW_USB_MAX_RECVBUF_SZ); the PCIe path does not. Add a check that new_len does not exceed the DMA buffer size.","publishedAt":"2026-08-15T06:22:43","lastModifiedAt":"2026-08-17T06:19:36","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74410","cvssScore":8.1,"cvssVector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","epssProbability":0.00278,"riskScore":0.83,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74410","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74410","en":"https://www.redsauce.net/en/cves/CVE-2026-74410","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74410","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74410","de":"https://www.redsauce.net/de/cves/CVE-2026-74410","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74410","el":"https://www.redsauce.net/el/cves/CVE-2026-74410"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74410"}}
