Linux Distros Unpatched Vulnerability : CVE-2026-72003

"The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - wifi: brcmfmac: cyw: fix heap overflow on a short auth frame brcmfnotifyauthframerx takes the frame length from the firmware event and copies the frame body wi...

CVE-2026-72003

A flaw was found in the Linux kernel's brcmfmac Wi-Fi driver. A remote attacker, by sending a specially crafted short authentication frame during the SAE Simultaneous Authentication of Equals authentication exchange, could trigger a heap overflow. This vulnerability allows for potential arbitrary...

CVE-2026-72003

CVE-2026-72003 observable in the Linux kernel affects the brcmfmac cyw WLAN driver. The issue arises in brcmf_notify_auth_frame_rx(), where the code derives mgmt_frame_len from e->datalen and subtracts offsetof(struct ieee80211_mgmt, u). If mgmt_frame_len is smaller than the 24-byte header off...

Vulnerability of the drivers/net/wireless/broadcom/brcm80211/brcmfmac component in the Linux operating system, which allows a hacker to cause a service failure

The vulnerability of the drivers/net/wireless/broadcom/brcm80211/brcmfmac component in the Linux operating system is related to pointer arithmetic errors. Exploiting this vulnerability can allow a remote attacker to cause service interruptions...

CVE-2026-68304

A flaw was found in the Linux kernel's brcmfmac Wi-Fi driver. When the driver operates in 802.1X-SHA256 authentication mode, it fails to correctly configure a firmware-related setting. This misconfiguration can trigger a kernel call trace warning during the execution of the brcmfcfg80211setpmk...

CVE-2026-68403

A flaw was found in the Linux kernel's brcmfmac Wi-Fi driver. During the driver's initialization and cleanup process, an uninitialized work item could be accessed and cancelled. This issue occurs if a specific memory allocation fails, leading to an invalid work drain. A local attacker could...
