  3. CVE-2024-43842
In the Linux kernel, the following vulnerability has been resolved: wifi: rtw89: Fix array index mistake in rtw89_sta_info_get_iter() In rtw89_sta_info_get_iter() 'status->he_gi' is compared to array size. But then 'rate->he_gi' is used as array index instead of 'status->he_gi'. This can lead to go beyond array boundaries in case of 'rate->he_gi' is not equal to 'status->he_gi' and is bigger than array size. Looks like "copy-paste" mistake. Fix this mistake by replacing 'rate->he_gi' with 'status->he_gi'. Found by Linux Verification Center (linuxtesting.org) with SVACE.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: rtw89: corrige el error de índice de matriz en rtw89_sta_info_get_iter() En rtw89_sta_info_get_iter() 'status->he_gi' se compara con el tamaño de la matriz. Pero luego se usa 'rate->he_gi' como índice de matriz en lugar de 'status->he_gi'. Esto puede llevar a ir más allá de los límites de la matriz en caso de que 'rate->he_gi' no sea igual a 'status->he_gi' y sea mayor que el tamaño de la matriz. Parece un error de "copiar y pegar". Corrija este error reemplazando 'rate->he_gi' con 'status->he_gi'. Encontrado por el Centro de verificación de Linux (linuxtesting.org) con SVACE.
