{"schema":"threatline.record/2","record":{"id":"CVE-2026-98190","aliases":[],"summary":"wifi: wilc1000: fix out-of-bounds read in P2P public action frames","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: wilc1000: fix out-of-bounds read in P2P public action frames\n\nwilc_wfi_p2p_rx() and mgmt_tx() start parsing a frame once\nieee80211_is_public_action() returns true. That helper only verifies the\nframe is long enough for the action category field, that is\noffsetofend(struct ieee80211_mgmt, u.action.category), 25 bytes. Both\nfunctions then read the P2P public action header up to oui_subtype at\noffset 30 and pass \"size - ie_offset\" to cfg80211_find_vendor_ie(), where\nie_offset is offsetof(struct ieee80211_mgmt, u) + sizeof(*d), i.e. 32.\n\nA public action frame of 25 to 31 bytes passes the check but is shorter\nthan that 32 byte header, so oui_subtype can be read out of bounds, and\nbecause the length is unsigned, \"size - ie_offset\" underflows to a value\nclose to 4 GiB. cfg80211_find_vendor_ie() takes an unsigned int length,\nso even the size_t subtraction in mgmt_tx() is truncated to the same\nvalue. It then walks far past the buffer searching for a vendor element\nuntil it reaches unmapped memory.\n\nIn the receive path the frame arrives over the air and needs no\nassociation, so a nearby unauthenticated device can crash the host while\nit is in P2P listen. Reject frames shorter than the P2P public action\nheader in both paths before dereferencing it.","categories":["Operating
