CVE-2026-89524

CVE-2026-89524 is an integer underflow in the Linux kernel's ath6kl Wi-Fi driver . In ath6kl_cfg80211_connect_event(), fixed IE offsets are subtracted from assoc_req_len (−4) and assoc_resp_len (−6), both of type u8, with no lower-bound check. When an association request or response is shorter th...

ROS-20260826-73-0008

The vulnerability of the ath6klhtcpiperxcomplete function in the drivers/net/wireless/ath/ath6kl/htcpipe.c file of the Atheros/Qualcomm wireless adapter driver in the Linux operating system is related to synchronization errors when using shared resources. Exploiting this vulnerability could allow...

SUSE CVE-2026-68353

In the Linux kernel, the following vulnerability has been resolved: wifi: ath6kl: fix OOB read from firmware nummsg in TX complete handler The firmware-controlled nummsg field u8, 0-255 drives the loop in ath6klwmitxcompleteeventrx without validation against the buffer length. This allows...

CVE-2026-68352

A flaw was found in the Linux kernel's ath6kl Wi-Fi driver. The driver does not properly validate the lengths of firmware-controlled information elements IEs during a connect event. This vulnerability allows the sum of these lengths to exceed the allocated buffer, resulting in an out-of-bounds...

CVE-2026-68198

A flaw was found in the Linux kernel's ath6kl Wi-Fi driver. A use-after-free vulnerability exists within the aggrresetstate function. This occurs because a non-synchronous timer deletion allows a timer callback aggrtimeout to access memory that has already been freed, creating a race condition. A...

CVE-2026-68199

A flaw was found in the Linux kernel's ath6kl Wi-Fi driver. This vulnerability allows a local attacker to cause an out-of-bounds memory access. The flaw occurs when the firmware provides an invalid window size during an ADDBA Add Block Ack request, leading to incorrect memory allocation. This can...
