According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  • A use-after-free flaw was found in fs/ext4/namei.c:dx_insert_block() in the Linux kernel’s filesystem sub- component. This flaw allows a local attacker with a user privilege to cause a denial of service.
    (CVE-2022-1184)

  • In l2cap_chan_put of l2cap_core, there is a possible use after free due to improper locking. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-165329981References:
    Upstream kernel (CVE-2022-20566)

  • An issue was discovered in the Linux kernel through 5.16-rc6. uapi_finalize in drivers/infiniband/core/uverbs_uapi.c lacks check of kmalloc_array(). (CVE-2022-3105)

  • An issue was discovered in the Linux kernel through 5.16-rc6. kfd_parse_subtype_iolink in drivers/gpu/drm/amd/amdkfd/kfd_crat.c lacks check of the return value of kmemdup(). (CVE-2022-3108)

  • A use-after-free flaw was found in the Linux kernel’s SGI GRU driver in the way the first gru_file_unlocked_ioctl function is called by the user, where a fail pass occurs in the gru_check_chiplet_assignment function. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-3424)

  • An incorrect read request flaw was found in the Infrared Transceiver USB driver in the Linux kernel. This issue occurs when a user attaches a malicious USB device. A local user could use this flaw to starve the resources, causing denial of service or potentially crashing the system. (CVE-2022-3903)

  • 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)

  • A flaw incorrect access control in the Linux kernel USB core subsystem was found in the way user attaches usb device. A local user could use this flaw to crash the system. (CVE-2022-4662)

  • 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)

  • cbq_classify in net/sched/sch_cbq.c in the Linux kernel through 6.1.4 allows attackers to cause a denial of service (slab-out-of-bounds read) because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results). (CVE-2023-23454)

  • 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
