EUVD-2026-55589

In the Linux kernel, the following vulnerability has been resolved: wifi: brcmfmac: initialize SDIO data work before cleanup brcmfsdioprobe stores the newly allocated bus in sdiodev-bus before allocating the ordered workqueue. If that allocation fails, the function jumps to fail and calls...

CVE-2026-68403

The CVE concerns the Linux kernel driver brcmfmac SDIO path. In brcmf_sdio_probe(), the newly allocated bus is stored in sdiodev->bus before the ordered workqueue is initialized. If allocation fails, the path can reach brcmf_sdio_remove(), which unconditionally cancels bus->datawork. The bu...

CVE-2026-68373

Summary: CVE-2026-68373 affects the Linux kernel Wi‑Fi driver at76c50x-usb. A length underflow in at76_guess_freq() can occur when processing truncated beacon/probe response frames, where el_off (36) is subtracted after a minimal 802.11 header check, causing an oversized IE length that leads to a...

CVE-2026-68355

The CVE-2026-68355 entry concerns the Linux kernel WiFi ATH11K driver. It describes a potential buffer underflow in ath11k_hal_rx_msdu_list_get() when the first msdu_details entry has a zero buffer address, causing access to msdu_details[i-1] with i == 0. The issue is mitigated by adding a separa...
