Descriptions

rtw_wx_set_scan in drivers/staging/rtl8188eu/os_dep/ioctl_linux.c in the Linux kernel through 5.11.6 allows writing beyond the end of the ->ssid[] array. NOTE: from the perspective of kernel.org releases, CVE IDs are not normally used for drivers/staging/* (unfinished work); however, system integrators may have situations in which a drivers/staging issue is relevant to their own customer base.

La función rtw_wx_set_scan en el archivo drivers/staging/rtl8188eu/os_dep/ioctl_linux.c en el kernel de Linux versiones hasta 5.11.6, permite escribir más allá del final de la matriz -)ssid[]. NOTA: desde la perspectiva de las versiones de kernel.org, las ID de CVE no se usan normalmente para drivers/staging/* (trabajo sin terminar); sin embargo, los integradores de sistemas pueden tener situaciones en las que un problema de drivers/staging sea relevante para su propia base de clientes
