rustls network-reachable panic in `Acceptor::accept`

A bug introduced in rustls 0.23.13 leads to a panic if the received TLS ClientHello is fragmented. Only servers that use rustls::server::Acceptor::accept are affected. Servers that use tokio-rustls's LazyConfigAcceptor API are affected. Servers that use tokio-rustls's TlsAcceptor API are not...

The vulnerability of the ip6_fragment() function in the Linux operating system’s IPv6 kernel implementation allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the ip6fragment function in the net/ipv6/ip6output.c module of the Linux operating system’s IPv6 kernel implementation is related to the reutilization of previously freed memory. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrit...

kernel: inet: inet_defrag: prevent sk release while still in use

In the Linux kernel, the following vulnerability has been resolved: inet: inetdefrag: prevent sk release while still in use iplocalout and other functions can pass skb-sk as function argument. If the skb is a fragment and reassembly happens before such function call returns, the sk must not be...

kernel: exfat: use kvmalloc_array/kvfree instead of kmalloc_array/kfree

A memory allocation failure was found in the exFAT filesystem driver. When system memory is fragmented, kmallocarray can fail to allocate contiguous memory for the bitmap, preventing USB drives from being mounted...
