Description:
Some vulnerabilities have been reported in the Linux Kernel, which can be exploited by malicious, local users to cause a DoS (Denial of Service), disclose potentially sensitive information, or to potentially gain escalated privileges.
1) An integer overflow error exists within the "get_fdb_entries()" function in net/bridge/br_ioctl.c. This can be exploited to cause a buffer overflow via specially crafted ioctl() requests.
Successful exploitation may allow the execution of arbitrary code with escalated privileges.
2) An error while copying memory from userspace on AMD64 platforms can be exploited to disclose potentially sensitive information.
3) An error in the "generic_file_splice_write()" function can be exploited to potentially gain escalated user or group privileges.
4) An error within the "udp_sendmsg()" function in net/ipv4/udp.c and the "udpv6_sendmsg()" function in net/ipv6/udp.c can be exploited to e.g. cause a crash.
