| Description: | NFS did not correctly handle races between fcntl and interrupts. A local attacker on an NFS mount could consume unlimited kernel memory, leading to a denial of service. Sparc syscalls did not correctly check mmap regions. A local attacker could cause a system panic, leading to a denial of service. In certain situations, cloned processes were able to send signals to parent processes, crossing privilege boundaries. A local attacker could send arbitrary signals to parent processes, leading to a denial of service. The 64-bit syscall interfaces did not correctly handle sign extension. A local attacker could make malicious syscalls, possibly gaining root privileges. The x86_64 architecture was not affected. The SCTP stack did not correctly validate FORWARD-TSN packets. A remote attacker could send specially crafted SCTP traffic causing a system crash, leading to a denial of service. The Dell platform device did not correctly validate user parameters. A local attacker could perform specially crafted reads to crash the system, leading to a denial of service. Network interfaces statistics for the SysKonnect FDDI driver did not check capabilities. A local user could reset statistics, potentially interfering with packet accounting systems. The getsockopt function did not correctly clear certain parameters. A local attacker could read leaked kernel memory, leading to a loss of privacy. The syscall interface did not correctly validate parameters when crossing the 64-bit/32-bit boundary. A local attacker could bypass certain syscall restricts via crafted syscalls. The shared memory subsystem did not correctly handle certain shmctl calls when CONFIG_SHMEM was disabled. Ubuntu kernels were not vulnerable, since CONFIG_SHMEM is enabled by default |
