Title: Linux Kernel 'FWD-TSN' Chunk Remote Buffer Overflow Vulnerability
Severity: CRITICAL
Description:
The Linux Kernel is prone to a buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data. Specifically, it fails to validate 'FWD-TSN' chunks. This error occurs in the 'sctp_disposition_t sctp_sf_eat_fwd_tsn()' function in the '/net/sctp/sm_statefuns.c' source file.
An attacker may be able to exploit this issue by constructing and sending malicious network data to the affected computer.
Successful exploits will allow the attacker to execute arbitrary code with kernel-level privileges, resulting in the complete compromise of affected computers. Failed exploit attempts will result in a denial-of-service condition.
The issue affects Linux Kernel 2.6.28; other versions may also be vulnerable.
