NIP6800;Secospace USG6600;USG9500 products versions of V500R001C30; V500R001C60SPC500; V500R005C00SPC100 have an invalid pointer access vulnerability. The software system access an invalid pointer when an abnormal condition occurs in certain operation. Successful exploit could cause certain process reboot. Affected product versions include:NIP6800 versions V500R001C30,V500R001C60SPC500;Secospace USG6600 versions V500R001C30SPC200,V500R001C30SPC600,V500R001C60SPC500;USG9500 versions V500R001C30SPC200,V500R001C30SPC600,V500R001C60SPC500.

NIP6800;Secospace USG6600;USG9500 products versions of V500R001C30; V500R001C60SPC500; V500R005C00SPC100 have a invalid pointer access vulnerability. The software system access an invalid pointer when operator logs in to the device and performs some operations. Successful exploit could cause certain process reboot.

Access of uninitialized pointer in the Intel(R) Trace Analyzer and Collector before version 2021.5 may allow an authenticated user to potentially enable denial of service via local access.

In the Linux kernel, the following vulnerability has been resolved: mac80211: track only QoS data frames for admission control For admission control, obviously all of that only works for QoS data frames, otherwise we cannot even access the QoS field in the header. Syzbot reported (see below) an uninitialized value here due to a status of a non-QoS nullfunc packet, which isn't even long enough to contain the QoS header. Fix this to only do anything for QoS data packets.

In the Linux kernel, the following vulnerability has been resolved: wifi: ath9k_htc: Use __skb_set_length() for resetting urb before resubmit Syzbot points out that skb_trim() has a sanity check on the existing length of the skb, which can be uninitialised in some error paths. The intent here is clearly just to reset the length to zero before resubmitting, so switch to calling __skb_set_length(skb, 0) directly. In addition, __skb_set_length() already contains a call to skb_reset_tail_pointer(), so remove the redundant call. The syzbot report came from ath9k_hif_usb_reg_in_cb(), but there's a similar usage of skb_trim() in ath9k_hif_usb_rx_cb(), change both while we're at it.
