Oracle Linux 7 : Unbreakable Enterprise kernel-container (ELSA-2023-12200)

high Nessus Plugin ID 172679

Synopsis

The remote Oracle Linux host is missing one or more security updates.

Description

The remote Oracle Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2023-12200 advisory.

- In drivers/media/dvb-core/dmxdev.c in the Linux kernel through 5.19.10, there is a use-after-free caused by refcount races, affecting dvb_demux_open and dvb_dmxdev_release. (CVE-2022-41218)

- An issue was discovered in the Linux kernel through 6.0.9. drivers/media/dvb-core/dvb_frontend.c has a race condition that can cause a use-after-free when a device is disconnected. (CVE-2022-45885)

- An issue was discovered in the Linux kernel through 6.0.10. l2cap_config_req in net/bluetooth/l2cap_core.c has an integer wraparound via L2CAP_CONF_REQ packets. (CVE-2022-45934)

- An out-of-bounds memory access flaw was found in the Linux kernel Intel's iSMT SMBus host controller driver in the way a user triggers the I2C_SMBUS_BLOCK_DATA (with the ioctl I2C_SMBUS) with malicious input data. This flaw allows a local user to crash the system. (CVE-2022-2873)

- An issue was discovered in the Linux kernel through 6.0.9. drivers/media/dvb-core/dvb_net.c has a .disconnect versus dvb_device_open race condition that leads to a use-after-free. (CVE-2022-45886)

- An issue was discovered in the Linux kernel through 6.0.9. drivers/media/dvb-core/dvbdev.c has a use- after-free, related to dvb_register_device dynamically allocating fops. (CVE-2022-45884)

- In the Linux kernel before 6.1.6, a NULL pointer dereference bug in the traffic control subsystem allows an unprivileged user to trigger a denial of service (system crash) via a crafted traffic control configuration that is set up with tc qdisc and tc class commands. This affects qdisc_graft in net/sched/sch_api.c. (CVE-2022-47929)

- A NULL pointer dereference flaw was found in rawv6_push_pending_frames in net/ipv6/raw.c in the network subcomponent in the Linux kernel. This flaw causes the system to crash. (CVE-2023-0394)

- atm_tc_enqueue in net/sched/sch_atm.c in the Linux kernel through 6.1.4 allows attackers to cause a denial of service because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results). (CVE-2023-23455)

- A vulnerability has been found in Linux Kernel and classified as critical. Affected by this vulnerability is the function area_cache_get of the file drivers/net/ethernet/netronome/nfp/nfpcore/nfp_cppcore.c of the component IPsec. The manipulation leads to use after free. It is recommended to apply a patch to fix this issue. The identifier VDB-211045 was assigned to this vulnerability. (CVE-2022-3545)

- An issue was discovered in the Linux kernel through 6.0.10. In drivers/media/dvb-core/dvb_ca_en50221.c, a use-after-free can occur is there is a disconnect after an open, because of the lack of a wait_event.
(CVE-2022-45919)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel-uek-container package.
