Title
wifi: wcn36xx: fix channel survey memory allocation size
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: wcn36xx: fix channel survey memory allocation size
KASAN reported a memory allocation issue in wcn->chan_survey
due to incorrect size calculation.
This commit uses kcalloc to allocate memory for wcn->chan_survey,
ensuring proper initialization and preventing the use of uninitialized
values when there are no frames on the channel.

"value": "AV:A - The out-of-bounds write is driven by `wcn36xx_rx_skb()` processing received 802.11 frames, so an attacker only needs to transmit/beacon within radio range of the victim\u0027s wcn36xx radio. This matches the WiFi frame-injection = Adjacent guidance.\nAC:L - The attacker chooses the channel (non-DFS 5 GHz UNII-3 channels 149-165 map to the furthest out-of-bounds offsets), and client devices scan those channels automatically and repeatedly; the uninitialized-memory disclosure via survey dump is deterministic on every boot.\nPR:N - `wcn36xx_update_survey()` runs on every frame at RX time, before mac80211 authentication/association, so an unauthenticated attacker with no credentials on any network triggers it. The corresponding read path is exposed through `NL80211_CMD_GET_SURVEY`, which carries no admin-permission flag and is dumpable by any unprivileged local user.\nUI:N - No victim action is required \u2014 wpa_supplicant/NetworkManager background scanning hops through the affected 5 GHz channels automatically, and a device merely operating on such a channel writes out of bounds on every received frame.\nS:U - The heap corruption and information disclosure are confined to the kernel\u0027s own memory and security authority, with no crossing into a hypervisor, IOMMU, or other separate security scope.\nC:H - `wcn36xx_get_survey()` reads up to 38 bytes past the 39-byte allocation and returns the values to userspace via the unprivileged nl80211 survey dump, and the missing zeroing leaks uninitialized kernel heap contents; the out-of-bounds access also provides a lever for broader disclosure.\nI:H - Received frames on high 5 GHz channels write attacker-influenced RSSI/SNR bytes at offsets 64-77 of a 39-byte allocation, corrupting the adjacent slab object \u2014 a heap out-of-bounds write, which scores High per the guidance.\nA:H - Corrupting neighbouring heap objects (and tripping KASAN/redzone or slab metadata checks) causes kernel oops or panic, and the write is triggerable repeatedly by any nearby unauthenticated transmitter."

This matches the WiFi frame-injection = Adjacent guidance.\nAC:L - The attacker chooses the channel (non-DFS 5 GHz UNII-3 channels 149-165 map to the furthest out-of-bounds offsets), and client devices scan those channels automatically and repeatedly; the uninitialized-memory disclosure via survey dump is deterministic on every boot.\nPR:N - `wcn36xx_update_survey()` runs on every frame at RX time, before mac80211 authentication/association, so an unauthenticated attacker with no credentials on any network triggers it. The corresponding read path is exposed through `NL80211_CMD_GET_SURVEY`, which carries no admin-permission flag and is dumpable by any unprivileged local user.\nUI:N - No victim action is required \u2014 wpa_supplicant/NetworkManager background scanning hops through the affected 5 GHz channels automatically, and a device merely operating on such a channel writes out of bounds on every received frame.\nS:U - The heap corruption and information disclosure are confined to the kernel\u0027s own memory and security authority, with no crossing into a hypervisor, IOMMU, or other separate security scope.\nC:H - `wcn36xx_get_survey()` reads up to 38 bytes past the 39-byte allocation and returns the values to userspace via the unprivileged nl80211 survey dump, and the missing zeroing leaks uninitialized kernel heap contents; the out-of-bounds access also provides a lever for broader disclosure.\nI:H - Received frames on high 5 GHz channels write attacker-influenced RSSI/SNR bytes at offsets 64-77 of a 39-byte allocation, corrupting the adjacent slab object \u2014 a heap out-of-bounds write, which scores High per the guidance.\nA:H - Corrupting neighbouring heap objects (and tripping KASAN/redzone or slab metadata checks) causes kernel oops or panic, and the write is triggerable repeatedly by any nearby unauthenticated transmitter."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
