Oracle Linux 6 / 7 : Unbreakable Enterprise kernel (ELSA-2018-4193)
high Nessus Plugin ID 111622
Language:
Synopsis
The remote Oracle Linux host is missing one or more security updates.Description
The remote Oracle Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2018-4193 advisory.- The acpi_smbus_hc_add function in drivers/acpi/sbshc.c in the Linux kernel through 4.14.15 allows local users to obtain sensitive address information by reading dmesg data from an SBS HC printk call.
(CVE-2018-5750)
- The futex_requeue function in kernel/futex.c in the Linux kernel before 4.14.15 might allow attackers to cause a denial of service (integer overflow) or possibly have unspecified other impact by triggering a negative wake or requeue value. (CVE-2018-6927)
- In the Linux kernel through 4.14.13, the rds_cmsg_atomic function in net/rds/rdma.c mishandles cases where page pinning fails or an invalid address is supplied, leading to an rds_atomic_free_op NULL pointer dereference. (CVE-2018-5333)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
