I'm announcing the release of the 6.0.2 kernel.

All users of the 6.0 kernel series must upgrade.

The updated 6.0.y git tree can be found at:

    git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-6.0.y

and can be browsed at the normal kernel.org git web browser:

Linux’s Wi-Fi code has some nasty bugs, which can be exploited simply by being near an attacker. Remote code execution is a possibility—no need to actually connect to a malicious Wi-Fi network.
They’ve been there for more than three years, and are caused by our old friend: Memory-unsafe C code. What other nasties lurk in the open source kernel powering billions of phones, routers and IoT devices?

Some drama and patching:

What appeared to be one simple Linux Wi-Fi networking security problem was soon revealed to be five different nasty Wi-Fi security problems. Fortunately, the patches are on their way.

Vulnerabilities in the Linux kernel enable code to be smuggled over WLAN

Attackers can use tampered WLAN packets to insert malicious code into a vulnerable Linux kernel. This pops up from an email from SUSE employee Marcus Meissner. So Sönke Huster of TU Darmstadt discovered one of the gaps.

UPDATE

By Sam Varghese:

iTWire - Developers patch five Wi-Fi bugs which were in Linux kernel since 2019

=> ↺ iTWire - Developers patch five Wi-Fi bugs which were in Linux kernel since 2019

Five Wi-Fi vulnerabilities in the Linux kernel have been patched and a new stable kernel, 5.10.148, released by stable kernel maintainer Greg Kroah-Hartman. The patches have also been included in the latest release, 6.1, by Linux creator Linus Torvalds.
Posting on the Linux Weekly News site, a subscriber with the moniker Johill said anyone who was scanning a network could be attacked using these flaws.
While one issue needed P2P functionality to be switched on, all five were a cause for concern for anyone who uses Wi-Fi.
The news was posted on LWN by editor Jonathan Corbet, himself a kernel developer, who wrote "anybody who uses Wi-Fi on untrusted networks should probably keep an eye out for the relevant updates". This was referred to as "tongue-in-cheek humour" by subscriber fmyhr, who wrote: "...anybody who uses WiFi on untrusted networks...' More tongue-in-cheek humour from our esteemed — albeit often grumpy — editor?"
