kernel: raw: Fix NULL deref in raw_get_next()

In the Linux kernel, the following vulnerability has been resolved: raw: Fix NULL deref in rawgetnext. Dae R. Jeong reported a NULL deref in rawgetnext 0. It seems that the repro was running these sequences in parallel so that one thread was iterating on a socket that was being freed in another...

kernel: ipv6: Fix an uninit variable access bug in __ip6_make_skb()

A flaw was identified in the Linux kernel’s IPv6 networking code in the function ip6makeskb. Under certain conditions—such as when using raw IPv6 sockets and processing ICMPv6 headers—the code may access an uninitialized variable because the expected header data is not guaranteed to reside in the...

PT-2023-8498

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.3 Description The issue is related to the IPv6 implementation in the Linux kernel, specifically with the net/ipv6/route.c file. It involves incorrect handling of boundary conditions, potentially allowing a remo...

Kubernetes Security Is Not Container Security

Container-specific security I recently had an interesting discussion with Gianluca Brindisi from Spotify about the differences between Kubernetes security and container security. Typically, the discussion about container security focuses on general questions that aren’t focused on a specific...
