CVE-2026-93789

The Linux kernel contains a vulnerability in the wifi: iwlwifi driver's firmware parser. The issue is caused by a failure to validate the ALIGN(tlv_len, 4) against the remaining parser length before consuming bytes from a firmware image. This oversight can lead to a length underflow when processi...

CVE-2026-93784

A vulnerability exists in the Linux kernel 's cfg80211 component. The function cfg80211_wext_siwgenie() fails to validate the IE buffer stored via SIOCSIWGENIE , leading to an out-of-bounds read in skip_ie() and an integer underflow in memcpy during a subsequent SIOCSIWESSID connection attempt. T...

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: RFCOMM: validate skb length in rfcommrecvframe rfcommrecvframe casts skb-data to struct rfcommhdr and dereferences hdr-addr and hdr-ctrl without validating skb-len first. A truncated frame with skb-len less than the...

CVE-2026-93783 Bluetooth: RFCOMM: validate skb length in rfcomm_recv_frame

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: RFCOMM: validate skb length in rfcommrecvframe rfcommrecvframe casts skb-data to struct rfcommhdr and dereferences hdr-addr and hdr-ctrl without validating skb-len first. A truncated frame with skb-len less than the...

CVE-2026-93783

The Linux kernel contains a vulnerability in the Bluetooth RFCOMM component within the rfcomm_recv_frame() function. The root cause is a missing length validation when casting skb->data to struct rfcomm_hdr. This allows a truncated frame to trigger an out-of-bounds read of uninitialized memory...
