Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: wifi: wilc1000: fix u8 overflow in
SSID scan buffer size calculation The variable valuesize is declared as u8 but accumulates the total
length of all SSIDs to scan. Each SSID contributes up to 33 bytes (IEEE80211_MAX_SSID_LEN + 1), and with
WILC_MAX_NUM_PROBED_SSID (10) SSIDs the total can reach 330, which wraps around to 74 when stored in a u8.
This causes kmalloc to allocate only 75 bytes while the subsequent memcpy writes up to 331 bytes into the
buffer, resulting in a 256-byte heap buffer overflow. Widen valuesize from u8 to u32 to accommodate the
full range. (CVE-2026-31780)
