wifi: cw1200: cap SSID length in cw1200_do_join()

2025-09-09T16:43:57+00:00

[ Upstream commit f8f15f6742b8874e59c9c715d0af3474608310ad ]

If the ssidie[1] length is more that 32 it leads to memory corruption.

wifi: cw1200: Avoid processing an invalid TIM IE

2024-09-04T11:14:53+00:00

[ Upstream commit b7bcea9c27b3d87b54075735c870500123582145 ]

While converting struct ieee80211_tim_ie::virtual_map to be a flexible
array it was observed that the TIM IE processing in cw1200_rx_cb()
could potentially process a malformed IE in a manner that could result
in a buffer over-read. Add logic to verify that the TIM IE length is
large enough to hold a valid TIM payload before processing it.

net/wireless: Delete unnecessary checks before the macro call “dev_kfree_skb”

2023-03-11T15:43:35+00:00

[ Upstream commit 868ad21496020ef83d41fdeed3b0a63de2a3caa5 ]

The dev_kfree_skb() function performs also input parameter validation.
Thus the test around the shown calls is not needed.

This issue was detected by using the Coccinelle software.

cw1200: add missing MODULE_DEVICE_TABLE

2021-07-19T06:53:11+00:00

[ Upstream commit dd778f89225cd258e8f0fed2b7256124982c8bb5 ]

This patch adds missing MODULE_DEVICE_TABLE definition which generates
correct modalias for automatic loading of this driver when it is built
as an external module.

Add the missing destroy_workqueue() before return from
cw1200_init_common in the error handling case.

cw1200: Fix a signedness bug in cw1200_load_firmware()

2020-01-23T07:22:55+00:00

commit 4a50d454502f1401171ff061a5424583f91266db upstream.

The "priv->hw_type" is an enum and in this context GCC will treat it
as an unsigned int so the error handling will never trigger.

cw1200: no need to check return value of debugfs_create functions

2019-02-01T12:34:56+00:00

When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.
