Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: ocb: don’t leave if not joined If there is no OCB state, do not ask the driver/mac80211 to leave, as that would only cause confusion. Since the chandef state can be set or cleared, this is a simple check...

kernel: Linux kernel: Wi-Fi subsystem out-of-bounds read via crafted frames

A flaw was found in the Linux kernel's Wi-Fi subsystem cfg80211. The cfg80211iselementinherited function does not properly validate the length of extension elements. A remote attacker, by sending a specially crafted Wi-Fi frame from an Access Point AP, could trigger a one-octet slab-out-of-bounds...

kernel: wifi: cfg80211: validate PMSR FTM preamble range

A flaw was found in the cfg80211 component of the Linux kernel's Wi-Fi subsystem. This vulnerability allows the PMSR FTM request parser to accept preamble values outside the defined nl80211 range. An attacker could exploit this by providing malformed input, potentially leading to unexpected syste...
