Title: Linux Kernel Sock_DGram_SendMsg Local Denial Of Service Vulnerability
Severity: MODERATE
Description:
The Linux kernel is reported to be prone to a local denial of service vulnerability. This vulnerability is reported to exist when 'CONFIG_SECURITY_NETWORK=y' and 'CONFIG_SECURITY_SELINUX=y' options are set in the Linux kernel.
It is reported that the vulnerability presents itself when SOCK_SEQPACKET UNIX domain sockets (AF_UNIX) are used. The issue exists in the sock_dgram_sendmsg code, specifically in the security_unix_may_send() function, and when triggered will cause a kernel panic.
A local attacker may exploit this vulnerability to trigger a kernel panic and effectively deny service to legitimate users.
