kernel: wifi: cfg80211: restrict NL80211_ATTR_TXQ_QUANTUM values

A vulnerability was found in the cfg80211 component in the Linux kernel, where a lack of proper range validation applied to the NL80211ATTRTXQQUANTUM can lead to a scenario where the userspace passes an extremely high value that the kernel is not designed to handle efficiently ex. 2^31. This can...

The vulnerability of the mac802154_llsec_key_del() function in the net/mac802154/llsec.c module of the Linux kernel’s wireless subsystem allows a attacker to compromise the confidentiality and integrity of protected information, or cause service failures.

The vulnerability of the mac802154llseckeydel function in the net/mac802154/llsec.c module of the Linux kernel’s wireless subsystem is related to the repeated use of previously freed memory. Exploiting this vulnerability could allow an attacker to compromise the confidentiality and integrity of...

kernel: wifi: cfg80211: ocb: don't leave if not joined

A flaw was found in the Linux kernel's cfg80211 wireless subsystem. When handling OCB Outside the Context of a BSS mode, the kernel may attempt to leave an OCB network even when not joined, which could cause driver confusion or unexpected behavior. This is a logic error in state management...

kernel: u8 overflow problem in cfg80211_update_notlisted_nontrans()

A buffer overflow flaw was found in the u8 overflow in cfg80211updatenotlistednontrans in net/wireless/scan.c in the Linux kernel’s wifi subcomponent. This flaw allows an attacker to crash the system or leak internal kernel information...

The vulnerability of the wireless communication subsystem in the Linux kernel’s net/mac802154/llsec.c module, which allows a hacker to cause a service failure.

The vulnerability in the wireless communication subsystem of the Linux kernel’s net/mac802154/llsec.c module relates to the assignment of a null pointer in the llseckeyalloc function during network connection termination. Exploiting this vulnerability could allow an attacker to cause a service...
