Linux Kernel TIPC Message Reassembly Use-After-Free Remote Code Execution Vulnerability

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Linux Kernel. Authentication is not required to exploit this vulnerability, but only systems with TIPC bearer enabled are vulnerable. The specific flaw exists within the processing of fragmented TIPC...

The vulnerability of the nci_free_device() function in the implementation of the NFC Controller Interface (NCI) in the Linux kernel allows a hacker to cause a service failure.

The vulnerability of the ncifreedevice function in the net/nfc/nci/data.c module, which is part of the NFC Controller Interface NCI implementation in the Linux operating system, is related to a packet overflow issue called “rxdatareassembly”. Exploiting this vulnerability could allow an attacker ...

The vulnerability of the inet_frag_reasm_prepare() function in the net/ipv4/inet_fragment.c module of the Linux operating system’s kernel-based IPv4 protocol implementation allows a attacker to cause a service failure.

The vulnerability of the inetfragreasmprepare function in the net/ipv4/inetfragment.c module of the Linux kernel’s IPv4 protocol implementation is related to the use of memory after it has been freed. Exploiting this vulnerability could allow an attacker to cause a service failure...

SUSE CVE-2024-26921

CVE-2024-26921

CVE-2024-26921 affects the Linux kernel inet_defrag path. The issue arises when ip_local_out() and similar calls pass skb->sk as an argument and the skb is a fragment undergoing reassembly; if reassembly happens before the call returns, the socket (skb->sk) must not be released. This can oc...
