Name of the Vulnerable Software and Affected Versions Linux Kernel (affected versions not specified)
Description An out-of-bounds array access exists in the WiFi wl1251 driver. The wl1251 tx packet cb() function uses a firmware completion ID, provided as a raw u8 from the completion block, to index the wl->tx frames[] array without verifying that the ID falls within the array's 16-entry limit.
Recommendations Restrict the use of the wl1251 tx packet cb() function or the wl1251 driver until a patch is applied. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
