delivered by mwifiex firmware (SDIO/PCIe/USB) into mwifiex_handle_rx_packet and the sta/uap/mgmt RX handlers; exploitation requires being on the same WiFi segment to inject or influence received frames, matching Adjacent for WiFi frame injection.\nAC:L - An adjacent attacker can reliably supply short or malformed RX payloads that yield a small but consistent rx_pkt_length passing the existing offset+length check and hitting the memmove underflow; success does not depend on an uncontrollable race or opaque victim-only state.\nPR:N - Frames are handled in the driver RX path with no host user account, capability, or OS authentication check; a peer on the WiFi link needs no privileges on the target system.\nUI:N - Once the interface is up with management/data RX enabled (common SoftAP, P2P, or station steady state on mwifiex Chromebooks/devices), attacker-controlled RX frames trigger the bug with no further victim action.\nS:U - The OOB read/write corrupts host kernel memory within the same kernel security authority; this is privilege escalation/DoS on the host, not a VM escape or IOMMU boundary cross.\nC:H - Out-of-bounds reads of skb data via unchecked rx_pkt_offset (eth/rfc1042 header access) and memory corruption from the underflowing memmove can be leveraged for arbitrary kernel information disclosure.\nI:H - The pkt_len underflow turns memmove into a large out-of-bounds write (explicitly called an exploitable OOB write on arm64 Chromebooks by the reporter), enabling heap corruption and control-flow hijacking.\nA:H - The same OOB access and corrupted memmove reliably cause kernel oops/panic in the RX path, so availability impact is complete even without a full code-execution exploit." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus":
