Description OSIDB Bzimport 2024-10-21 19:09:33 UTC

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

wifi: rtw89: avoid reading out of bounds when loading TX power FW elements

Because the loop-expression will do one more time before getting false from
cond-expression, the original code copied one more entry size beyond valid
region.

Fix it by moving the entry copy to loop-body.
