The vulnerability of the `ieee80211_parse_tx_radiotap()` function in the `net/mac80211/tx.c` module of the `mac80211` stack implementation in the Linux operating system allows a hacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the ieee80211parsetxradiotap function in the net/mac80211/tx.c module of the mac80211 stack implementation in the Linux operating system is related to an incorrect bitwise shift of a integer value. Exploiting this vulnerability could allow an attacker to compromise the...

The vulnerability of the function ieee80211_radiotap_iterator_next() in the net/wireless/radiotap.c module, which is part of Linux’s wireless communication support, allows a malicious actor to cause a service failure.

The vulnerability of the function ieee80211radiotapiteratornext in the net/wireless/radiotap.c module, which is part of Linux’s wireless communication support, is related to the dependence on unspecified behavior for each implementation type. Exploiting this vulnerability could allow an attacker ...
