CVE-2026-53178

Status: ModifiedHigh (8.1)—

In the Linux kernel, the following vulnerability has been resolved:

staging: rtl8723bs: rtw_mlme: add bounds checks before ie_length subtraction

Add guards to ensure ie_length is large enough before subtracting fixed IE offsets to prevent unsigned integer underflow.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

AV:A (red adyacente), acceso sin privilegios. CWE-191 (integer underflow) en procesamiento de tramas IE del kernel WiFi puede causar DoS (A:H) o escalada local (I:N pero A:H sugiere corrupción de memoria).

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
