(CVE-2019-6974)\n\n - The KVM implementation in the Linux kernel through 4.20.5 has a Use-after-Free. (CVE-2019-7221)\n\n - The KVM implementation in the Linux kernel through 4.20.5 has an Information Leak. (CVE-2019-7222)\n\n - A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after- free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out. (CVE-2018-16884)\n\n - A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the mwifiex kernel module while connecting to a malicious wireless network. (CVE-2019-3846)\n\n - The Linux kernel before 5.1-rc5 allows page->_refcount reference count overflow, with resultant use-after- free issues, if about 140 GiB of RAM exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c, include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can occur with FUSE requests. (CVE-2019-11487)\n\n - An issue was discovered in the Linux kernel before 4.18.7. In block/blk-core.c, there is an\n __blk_drain_queue() use-after-free because a certain error case is mishandled. (CVE-2018-20856)\n\n - The SCTP socket buffer used by a userspace application is not accounted by the cgroups subsystem. An attacker can use this flaw to cause a denial of service attack. Kernel 3.10.x and 4.18.x branches are believed to be vulnerable. (CVE-2019-3874)\n\n - The fix for CVE-2019-11599, affecting the Linux kernel before 5.0.10 was not complete. A local user could use this flaw to obtain sensitive information, cause a denial of service, or possibly have other unspecified impacts by triggering a race condition with mmget_not_zero or get_task_mm calls.\n (CVE-2019-14898)\n\n - In the Linux kernel before 5.0.6, there is a NULL pointer dereference in drop_sysctl_table() in fs/proc/proc_sysctl.c, related to put_links, aka CID-23da9588037e. (CVE-2019-20054)\n\n - An issue was discovered in net/wireless/nl80211.c in the Linux kernel through 5.2.17. It does not check the length of variable elements in a beacon head, leading to a buffer overflow. (CVE-2019-16746)\n\n - In the Linux kernel 5.4.0-rc2, there is a use-after-free (read) in the __blk_add_trace function in kernel/trace/blktrace.c (which is used to fill out a blk_io_trace structure and place it in a per-cpu sub- buffer). (CVE-2019-19768)\n\n - In the Linux kernel through 5.4.6, there is a NULL pointer dereference in drivers/scsi/libsas/sas_discover.c because of mishandling of port disconnection during discovery, related to a PHY down race condition, aka CID-f70267f379b5. (CVE-2019-19965)\n\n - In the Linux kernel before 5.1, there is a memory leak in __feat_register_sp() in net/dccp/feat.c, which may cause denial of service, aka CID-1d3ff0950e2b. (CVE-2019-20096)\n\n - A flaw was found in the Linux kernel's implementation of some networking protocols in IPsec, such as VXLAN and GENEVE tunnels over IPv6. When an encrypted tunnel is created between two hosts, the kernel isn't correctly routing tunneled data over the encrypted link; rather sending the data unencrypted. This would allow anyone in between the two endpoints to read the traffic unencrypted. The main threat from this vulnerability is to data confidentiality. (CVE-2020-1749)\n\n - Memory leaks in drivers/net/wireless/ath/ath9k/htc_hst.c in the Linux kernel through 5.3.11 allow attackers to cause a denial of service (memory consumption) by triggering wait_for_completion_timeout() failures. This affects the htc_config_pipe_credits() function, the htc_setup_complete() function, and the htc_connect_service() function, aka CID-853acf7caf10. (CVE-2019-19073)\n\n - drivers/media/usb/dvb-usb/technisat-usb2.c in the Linux kernel through 5.2.9 has an out-of-bounds read via crafted USB device traffic (which may be remote via usbip or usbredir). (CVE-2019-15505)\n\n - An issue was discovered in the Linux kernel before 5.4.7. The prb_calc_retire_blk_tmo() function in net/packet/af_packet.c can result in a denial of service (CPU consumption and soft lockup) in a certain failure case involving TPACKET_V3, aka CID-b43d1f9f7067. (CVE-2019-20812)\n\n - A flaw was found in the Linux kernels implementation of the invert video code on VGA consoles when a local attacker attempts to resize the console, calling an ioctl VT_RESIZE, which causes an out-of-bounds write to occur. This flaw allows a local user with access to the VGA console to crash the system, potentially escalating their privileges on the system. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2020-14331)\n\n - fs/btrfs/volumes.c in the Linux kernel before 5.1 allows a btrfs_verify_dev_extents NULL pointer dereference via a crafted btrfs image because fs_devices->devices is mishandled within find_device, aka CID-09ba3bc9dd15. (CVE-2019-18885)\n\n - A buffer over-read flaw was found in RH kernel versions before 5.0 in crypto_authenc_extractkeys in crypto/authenc.c in the IPsec Cryptographic algorithm's module, authenc. When a payload longer than 4 bytes, and is not following 4-byte alignment boundary guidelines, it causes a buffer over-read threat, leading to a system crash. This flaw allows a local attacker with user privileges to cause a denial of service. (CVE-2020-10769)\n\n - A flaw was found in the Linux kernels SELinux LSM hook implementation before version 5.7, where it incorrectly assumed that an skb would only contain a single netlink message. The hook would incorrectly only validate the first netlink message in the skb and allow or deny the rest of the messages within the skb with the granted permission without further processing. (CVE-2020-10751)\n\n - An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3. An attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations before the required authentication process has completed. This could lead to different denial-of-service scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already existing clients in other nearby APs of the same wireless infrastructure. An attacker can forge Authentication and Association Request packets to trigger this vulnerability. (CVE-2019-5108)\n\n - An issue was discovered in write_tpt_entry in drivers/infiniband/hw/cxgb4/mem.c in the Linux kernel through 5.3.2. The cxgb4 driver is directly calling dma_map_single (a DMA function) from a stack variable.\n This could allow an attacker to trigger a Denial of Service, exploitable if this driver is used on an architecture for which this stack/DMA interaction has security relevance. (CVE-2019-17075)\n\n - An issue was discovered in the Linux kernel before 5.1.8. There is a NULL pointer dereference caused by a malicious USB device in the drivers/media/usb/siano/smsusb.c driver. (CVE-2019-15218)\n\n - A memory leak in the gs_can_open() function in drivers/net/can/usb/gs_usb.c in the Linux kernel before 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering usb_submit_urb() failures, aka CID-fb5be6a7b486. (CVE-2019-19052)\n\n - An issue was discovered in fs/gfs2/rgrp.c in the Linux kernel before 4.8. A use-after-free is caused by the functions gfs2_clear_rgrpd and read_rindex_entry. (CVE-2016-10905)\n\n - An issue was discovered in drivers/net/ethernet/arc/emac_main.c in the Linux kernel before 4.5. A use- after-free is caused by a race condition between the functions arc_emac_tx and arc_emac_tx_clean.\n (CVE-2016-10906)\n\n - The omninet_open function in drivers/usb/serial/omninet.c in the Linux kernel before 4.10.4 allows local users to cause a denial of service (tty exhaustion) by leveraging reference count mishandling.\n (CVE-2017-8925)\n\n - A memory out-of-bounds read flaw was found in the Linux kernel before 5.9-rc2 with the ext3/ext4 file system, in the way it accesses a directory with broken indexing. This flaw allows a local user to crash the system if the directory exists. The highest threat from this vulnerability is to system availability.\n (CVE-2020-14314)\n\n - sound/core/seq_device.c in the Linux kernel before 4.13.4 allows local users to cause a denial of service (snd_rawmidi_dev_seq_free use-after-free and system crash) or possibly have unspecified other impact via a crafted USB device. (CVE-2017-16528)\n\n - The edge_bulk_in_callback function in drivers/usb/serial/io_ti.c in the Linux kernel before 4.10.4 allows local users to obtain sensitive information (in the dmesg ringbuffer and syslog) from uninitialized kernel memory by using a crafted USB device (posing as an io_ti USB serial device) to trigger an integer underflow. (CVE-2017-8924)\n\n - In driver_override_store and driver_override_show of bus.c, there is a possible double free due to improper locking. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Product: Android Versions: Android kernel Android ID: A-69129004 References: Upstream kernel. (CVE-2018-9415)\n\n - An issue was discovered in the Linux kernel before 4.20.2. An out-of-bounds access exists in the function build_audio_procunit in the file sound/usb/mixer.c. (CVE-2019-15927)\n\n - A flaw was found in the Linux kernel's implementation of GRO in versions before 5.2. This flaw allows an attacker with local access to crash the system. (CVE-2020-10720)\n\n - A TOCTOU mismatch in the NFS client code in the Linux kernel before 5.8.3 could be used by local attackers to corrupt memory or possibly have unspecified other impact because a size check is in fs/nfs/nfs4proc.c instead of fs/nfs/nfs4xdr.c, aka CID-b4487b935452.

(CVE-2019-6974)\n\n - The KVM implementation in the Linux kernel through 4.20.5 has a Use-after-Free. (CVE-2019-7221)\n\n - The KVM implementation in the Linux kernel through 4.20.5 has an Information Leak. (CVE-2019-7222)\n\n - A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares mounted in different network\n namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after-\n free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system\n panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out. (CVE-2018-16884)\n\n - A flaw that allowed an attacker to corrupt memory and possibly escalate privileges was found in the\n mwifiex kernel module while connecting to a malicious wireless network. (CVE-2019-3846)\n\n - The Linux kernel before 5.1-rc5 allows page->_refcount reference count overflow, with resultant use-after-\n free issues, if about 140 GiB of RAM exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c,\n include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can\n occur with FUSE requests. (CVE-2019-11487)\n\n - An issue was discovered in the Linux kernel before 4.18.7. In block/blk-core.c, there is an\n __blk_drain_queue() use-after-free because a certain error case is mishandled. (CVE-2018-20856)\n\n - The SCTP socket buffer used by a userspace application is not accounted by the cgroups subsystem. An\n attacker can use this flaw to cause a denial of service attack. Kernel 3.10.x and 4.18.x branches are\n believed to be vulnerable. (CVE-2019-3874)\n\n - The fix for CVE-2019-11599, affecting the Linux kernel before 5.0.10 was not complete. A local user could\n use this flaw to obtain sensitive information, cause a denial of service, or possibly have other\n unspecified impacts by triggering a race condition with mmget_not_zero or get_task_mm calls.\n (CVE-2019-14898)\n\n - In the Linux kernel before 5.0.6, there is a NULL pointer dereference in drop_sysctl_table() in\n fs/proc/proc_sysctl.c, related to put_links, aka CID-23da9588037e. (CVE-2019-20054)\n\n - An issue was discovered in net/wireless/nl80211.c in the Linux kernel through 5.2.17. It does not check\n the length of variable elements in a beacon head, leading to a buffer overflow. (CVE-2019-16746)\n\n - In the Linux kernel 5.4.0-rc2, there is a use-after-free (read) in the __blk_add_trace function in\n kernel/trace/blktrace.c (which is used to fill out a blk_io_trace structure and place it in a per-cpu sub-\n buffer). (CVE-2019-19768)\n\n - In the Linux kernel through 5.4.6, there is a NULL pointer dereference in\n drivers/scsi/libsas/sas_discover.c because of mishandling of port disconnection during discovery, related\n to a PHY down race condition, aka CID-f70267f379b5. (CVE-2019-19965)\n\n - In the Linux kernel before 5.1, there is a memory leak in __feat_register_sp() in net/dccp/feat.c, which\n may cause denial of service, aka CID-1d3ff0950e2b. (CVE-2019-20096)\n\n - A flaw was found in the Linux kernel's implementation of some networking protocols in IPsec, such as VXLAN\n and GENEVE tunnels over IPv6. When an encrypted tunnel is created between two hosts, the kernel isn't\n correctly routing tunneled data over the encrypted link; rather sending the data unencrypted. This would\n allow anyone in between the two endpoints to read the traffic unencrypted. The main threat from this\n vulnerability is to data confidentiality. (CVE-2020-1749)\n\n - Memory leaks in drivers/net/wireless/ath/ath9k/htc_hst.c in the Linux kernel through 5.3.11 allow\n attackers to cause a denial of service (memory consumption) by triggering wait_for_completion_timeout()\n failures. This affects the htc_config_pipe_credits() function, the htc_setup_complete() function, and the\n htc_connect_service() function, aka CID-853acf7caf10. (CVE-2019-19073)\n\n - drivers/media/usb/dvb-usb/technisat-usb2.c in the Linux kernel through 5.2.9 has an out-of-bounds read via\n crafted USB device traffic (which may be remote via usbip or usbredir). (CVE-2019-15505)\n\n - An issue was discovered in the Linux kernel before 5.4.7. The prb_calc_retire_blk_tmo() function in\n net/packet/af_packet.c can result in a denial of service (CPU consumption and soft lockup) in a certain\n failure case involving TPACKET_V3, aka CID-b43d1f9f7067. (CVE-2019-20812)\n\n - A flaw was found in the Linux kernels implementation of the invert video code on VGA consoles when a\n local attacker attempts to resize the console, calling an ioctl VT_RESIZE, which causes an out-of-bounds\n write to occur. This flaw allows a local user with access to the VGA console to crash the system,\n potentially escalating their privileges on the system. The highest threat from this vulnerability is to\n data confidentiality and integrity as well as system availability. (CVE-2020-14331)\n\n - fs/btrfs/volumes.c in the Linux kernel before 5.1 allows a btrfs_verify_dev_extents NULL pointer\n dereference via a crafted btrfs image because fs_devices->devices is mishandled within find_device, aka\n CID-09ba3bc9dd15. (CVE-2019-18885)\n\n - A buffer over-read flaw was found in RH kernel versions before 5.0 in crypto_authenc_extractkeys in\n crypto/authenc.c in the IPsec Cryptographic algorithm's module, authenc. When a payload longer than 4\n bytes, and is not following 4-byte alignment boundary guidelines, it causes a buffer over-read threat,\n leading to a system crash. This flaw allows a local attacker with user privileges to cause a denial of\n service. (CVE-2020-10769)\n\n - A flaw was found in the Linux kernels SELinux LSM hook implementation before version 5.7, where it\n incorrectly assumed that an skb would only contain a single netlink message. The hook would incorrectly\n only validate the first netlink message in the skb and allow or deny the rest of the messages within the\n skb with the granted permission without further processing. (CVE-2020-10751)\n\n - An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3. An\n attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations\n before the required authentication process has completed. This could lead to different denial-of-service\n scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already\n existing clients in other nearby APs of the same wireless infrastructure. An attacker can forge\n Authentication and Association Request packets to trigger this vulnerability. (CVE-2019-5108)\n\n - An issue was discovered in write_tpt_entry in drivers/infiniband/hw/cxgb4/mem.c in the Linux kernel\n through 5.3.2. The cxgb4 driver is directly calling dma_map_single (a DMA function) from a stack variable.\n This could allow an attacker to trigger a Denial of Service, exploitable if this driver is used on an\n architecture for which this stack/DMA interaction has security relevance. (CVE-2019-17075)\n\n - An issue was discovered in the Linux kernel before 5.1.8. There is a NULL pointer dereference caused by a\n malicious USB device in the drivers/media/usb/siano/smsusb.c driver. (CVE-2019-15218)\n\n - A memory leak in the gs_can_open() function in drivers/net/can/usb/gs_usb.c in the Linux kernel before\n 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering usb_submit_urb()\n failures, aka CID-fb5be6a7b486. (CVE-2019-19052)\n\n - An issue was discovered in fs/gfs2/rgrp.c in the Linux kernel before 4.8. A use-after-free is caused by\n the functions gfs2_clear_rgrpd and read_rindex_entry. (CVE-2016-10905)\n\n - An issue was discovered in drivers/net/ethernet/arc/emac_main.c in the Linux kernel before 4.5. A use-\n after-free is caused by a race condition between the functions arc_emac_tx and arc_emac_tx_clean.\n (CVE-2016-10906)\n\n - The omninet_open function in drivers/usb/serial/omninet.c in the Linux kernel before 4.10.4 allows local\n users to cause a denial of service (tty exhaustion) by leveraging reference count mishandling.\n (CVE-2017-8925)\n\n - A memory out-of-bounds read flaw was found in the Linux kernel before 5.9-rc2 with the ext3/ext4 file\n system, in the way it accesses a directory with broken indexing. This flaw allows a local user to crash\n the system if the directory exists. The highest threat from this vulnerability is to system availability.\n (CVE-2020-14314)\n\n - sound/core/seq_device.c in the Linux kernel before 4.13.4 allows local users to cause a denial of service\n (snd_rawmidi_dev_seq_free use-after-free and system crash) or possibly have unspecified other impact via a\n crafted USB device. (CVE-2017-16528)\n\n - The edge_bulk_in_callback function in drivers/usb/serial/io_ti.c in the Linux kernel before 4.10.4 allows\n local users to obtain sensitive information (in the dmesg ringbuffer and syslog) from uninitialized kernel\n memory by using a crafted USB device (posing as an io_ti USB serial device) to trigger an integer\n underflow. (CVE-2017-8924)\n\n - In driver_override_store and driver_override_show of bus.c, there is a possible double free due to\n improper locking. This could lead to local escalation of privilege with System execution privileges\n needed. User interaction is not needed for exploitation. Product: Android Versions: Android kernel Android\n ID: A-69129004 References: Upstream kernel. (CVE-2018-9415)\n\n - An issue was discovered in the Linux kernel before 4.20.2. An out-of-bounds access exists in the function\n build_audio_procunit in the file sound/usb/mixer.c. (CVE-2019-15927)\n\n - A flaw was found in the Linux kernel's implementation of GRO in versions before 5.2. This flaw allows an\n attacker with local access to crash the system. (CVE-2020-10720)\n\n - A TOCTOU mismatch in the NFS client code in the Linux kernel before 5.8.3 could be used by local attackers\n to corrupt memory or possibly have unspecified other impact because a size check is in fs/nfs/nfs4proc.c\n instead of fs/nfs/nfs4xdr.c, aka CID-b4487b935452. (CVE-2020-25212)\n\n - The rbd block device driver in drivers/block/rbd.c in the Linux kernel through 5.8.9 used incomplete\n permission checking for access to rbd devices, which could be leveraged by local attackers to map or unmap\n rbd block devices, aka CID-f44d04e696fe. (CVE-2020-25284)\n\n - A race condition between hugetlb sysctl handlers in mm/hugetlb.c in the Linux kernel before 5.8.8 could be\n used by local attackers to corrupt memory, cause a NULL pointer dereference, or possibly have unspecified\n other impact, aka CID-17743798d812.

as referenced in the ELSA-2020-5837 advisory.\n\n - In the Linux kernel before 5.1.7, a device can be tracked by an attacker using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic is sent to multiple destination IP addresses, it is possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). An attack may be conducted by hosting a crafted web page that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses. (CVE-2019-10638)\n\n - The Linux kernel 4.x (starting from 4.1) and 5.x before 5.0.8 allows Information Exposure (partial kernel address disclosure), leading to a KASLR bypass. Specifically, it is possible to extract the KASLR kernel image offset using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic is sent to multiple destination IP addresses, it is possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This key contains enough bits from a kernel address (of a static variable) so when the key is extracted (via enumeration), the offset of the kernel image is exposed. This attack can be carried out remotely, by the attacker forcing the target device to send UDP or ICMP (or certain other) traffic to attacker-controlled IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server. ICMP traffic is trivial if the server answers ICMP Echo requests (ping). For client targets, if the target visits the attacker's web page, then WebRTC or gQUIC can be used to force UDP traffic to attacker-controlled IP addresses. NOTE: this attack against KASLR became viable in 4.1 because IP ID generation was changed to have a dependency on an address associated with a network namespace. (CVE-2019-10639)\n\n - A memory leak in the crypto_report() function in crypto/crypto_user_base.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering crypto_report_alg() failures, aka CID-ffdde5932042. (CVE-2019-19062)\n\n - A flaw was found in the Linux kernel's implementation of Userspace core dumps. This flaw allows an attacker with a local account to crash a trivial program and exfiltrate private kernel data.\n (CVE-2020-10732)\n\n - ** DISPUTED ** A memory leak in the unittest_data_add() function in drivers/of/unittest.c in the Linux kernel before 5.3.10 allows attackers to cause a denial of service (memory consumption) by triggering of_fdt_unflatten_tree() failures, aka CID-e13de8fe0d6a. NOTE: third parties dispute the relevance of this because unittest.c can only be reached during boot. (CVE-2019-19049)\n\n - An issue was discovered in the Linux kernel before 5.0.6. In rx_queue_add_kobject() and netdev_queue_add_kobject() in net/core/net-sysfs.c, a reference count is mishandled, aka CID-a3e23f719f5c.\n (CVE-2019-20811)\n\n - The hdpvr_probe function in drivers/media/usb/hdpvr/hdpvr-core.c in the Linux kernel through 4.13.11 allows local users to cause a denial of service (improper error handling and system crash) or possibly have unspecified other impact via a crafted USB device. (CVE-2017-16644)\n\n - In the Linux kernel before 5.2.9, there is an info-leak bug that can be caused by a malicious USB device in the drivers/net/can/usb/peak_usb/pcan_usb_fd.c driver, aka CID-30a8beeb3042.

"2023-05-23T14:18:56", "description": "The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2020-5845 advisory.\n\n - A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after- free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out. (CVE-2018-16884)\n\n - An infinite loop issue was found in the vhost_net kernel module in Linux Kernel up to and including v5.1-rc6, while handling incoming packets in handle_rx(). It could occur if one end sends packets faster than the other end can process them. A guest user, maybe remote one, could use this flaw to stall the vhost_net kernel thread, resulting in a DoS scenario. (CVE-2019-3900)\n\n - The Linux kernel before 5.1-rc5 allows page->_refcount reference count overflow, with resultant use-after- free issues, if about 140 GiB of RAM exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c, include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can occur with FUSE requests. (CVE-2019-11487)\n\n - In the Linux kernel before 5.1.7, a device can be tracked by an attacker using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic is sent to multiple destination IP addresses, it is possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). An attack may be conducted by hosting a crafted web page that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses. (CVE-2019-10638)\n\n - The SCTP socket buffer used by a userspace application is not accounted by the cgroups subsystem. An attacker can use this flaw to cause a denial of service attack. Kernel 3.10.x and 4.18.x branches are believed to be vulnerable. (CVE-2019-3874)\n\n - The fix for CVE-2019-11599, affecting the Linux kernel before 5.0.10 was not complete. A local user could use this flaw to obtain sensitive information, cause a denial of service, or possibly have other unspecified impacts by triggering a race condition with mmget_not_zero or get_task_mm calls.\n (CVE-2019-14898)\n\n - In the Linux kernel through 5.3.2, cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c does not reject a long SSID IE, leading to a Buffer Overflow. (CVE-2019-17133)\n\n - An issue was discovered in net/wireless/nl80211.c in the Linux kernel through 5.2.17. It does not check the length of variable elements in a beacon head, leading to a buffer overflow. (CVE-2019-16746)\n\n - The Linux kernel 4.x (starting from 4.1) and 5.x before 5.0.8 allows Information Exposure (partial kernel address disclosure), leading to a KASLR bypass. Specifically, it is possible to extract the KASLR kernel image offset using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic is sent to multiple destination IP addresses, it is possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This key contains enough bits from a kernel address (of a static variable) so when the key is extracted (via enumeration), the offset of the kernel image is exposed. This attack can be carried out remotely, by the attacker forcing the target device to send UDP or ICMP (or certain other) traffic to attacker-controlled IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server. ICMP traffic is trivial if the server answers ICMP Echo requests (ping). For client targets, if the target visits the attacker's web page, then WebRTC or gQUIC can be used to force UDP traffic to attacker-controlled IP addresses. NOTE: this attack against KASLR became viable in 4.1 because IP ID generation was changed to have a dependency on an address associated with a network namespace. (CVE-2019-10639)\n\n - Memory leaks in drivers/net/wireless/ath/ath9k/htc_hst.c in the Linux kernel through 5.3.11 allow attackers to cause a denial of service (memory consumption) by triggering wait_for_completion_timeout() failures. This affects the htc_config_pipe_credits() function, the htc_setup_complete() function, and the htc_connect_service() function, aka CID-853acf7caf10. (CVE-2019-19073)\n\n - A memory leak in the ath9k_wmi_cmd() function in drivers/net/wireless/ath/ath9k/wmi.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption), aka CID-728c1e2a05e4.\n (CVE-2019-19074)\n\n - kernel/sched/fair.c in the Linux kernel before 5.3.9, when cpu.cfs_quota_us is used (e.g., with Kubernetes), allows attackers to cause a denial of service against non-cpu-bound applications by generating a workload that triggers unwanted slice expiration, aka CID-de53fd7aedb1. (In other words, although this slice expiration would typically be seen with benign workloads, it is possible that an attacker could calculate how many stray requests are required to force an entire Kubernetes cluster into a low-performance state caused by slice expiration, and ensure that a DDoS attack sent that number of stray requests. An attack does not affect the stability of the kernel; it only causes mismanagement of application execution.) (CVE-2019-19922)\n\n - A flaw was found in the Linux kernel before 5.8-rc1 in the implementation of the Enhanced IBPB (Indirect Branch Prediction Barrier). The IBPB mitigation will be disabled when STIBP is not available or when the Enhanced Indirect Branch Restricted Speculation (IBRS) is available. This flaw allows a local attacker to perform a Spectre V2 style attack when this configuration is active. The highest threat from this vulnerability is to confidentiality. (CVE-2020-10767)\n\n - In the Linux kernel before 5.2.9, there is an info-leak bug that can be caused by a malicious USB device in the drivers/net/can/usb/peak_usb/pcan_usb_fd.c driver, aka CID-30a8beeb3042. (CVE-2019-19535)\n\n - An issue was discovered in the Linux kernel before 5.4.7. The prb_calc_retire_blk_tmo() function in net/packet/af_packet.c can result in a denial of service (CPU consumption and soft lockup) in a certain failure case involving TPACKET_V3, aka CID-b43d1f9f7067. (CVE-2019-20812)\n\n - A flaw was found in the Linux kernels implementation of the invert video code on VGA consoles when a local attacker attempts to resize the console, calling an ioctl VT_RESIZE, which causes an out-of-bounds write to occur. This flaw allows a local user with access to the VGA console to crash the system, potentially escalating their privileges on the system. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2020-14331)\n\n - fs/btrfs/volumes.c in the Linux kernel before 5.1 allows a btrfs_verify_dev_extents NULL pointer dereference via a crafted btrfs image because fs_devices->devices is mishandled within find_device, aka CID-09ba3bc9dd15. (CVE-2019-18885)\n\n - In the Linux kernel before 5.7.8, fs/nfsd/vfs.c (in the NFS server) can set incorrect permissions on new filesystem objects when the filesystem lacks ACL support, aka CID-22cf8419f131. This occurs because the current umask is not considered. (CVE-2020-24394)\n\n - A flaw was found in the Linux Kernel before 5.8-rc6 in the ZRAM kernel module, where a user with a local account and the ability to read the /sys/class/zram-control/hot_add file can create ZRAM device nodes in the /dev/ directory. This read allocates kernel memory and is not accounted for a user that triggers the creation of that ZRAM device. With this vulnerability, continually reading the device may consume a large amount of system memory and cause the Out-of-Memory (OOM) killer to activate and terminate random userspace processes, possibly making the system inoperable. (CVE-2020-10781)\n\n - The Linux kernel through 5.7.11 allows remote attackers to make observations that help to obtain sensitive information about the internal state of the network RNG, aka CID-f227e3ec3b5c. This is related to drivers/char/random.c and kernel/time/timer.c. (CVE-2020-16166)\n\n - An issue was discovered in the Linux kernel through 4.17.10. There is an invalid pointer dereference in io_ctl_map_page() when mounting and operating a crafted btrfs image, because of a lack of block group item validation in check_leaf_item in fs/btrfs/tree-checker.c. (CVE-2018-14613)\n\n - A buffer over-read flaw was found in RH kernel versions before 5.0 in crypto_authenc_extractkeys in crypto/authenc.c in the IPsec Cryptographic algorithm's module, authenc. When a payload longer than 4 bytes, and is not following 4-byte alignment boundary guidelines, it causes a buffer over-read threat, leading to a system crash. This flaw allows a local attacker with user privileges to cause a denial of service. (CVE-2020-10769)\n\n - A pivot_root race condition in fs/namespace.c in the Linux kernel 4.4.x before 4.4.221, 4.9.x before 4.9.221, 4.14.x before 4.14.178, 4.19.x before 4.19.119, and 5.x before 5.3 allows local users to cause a denial of service (panic) by corrupting a mountpoint reference counter. (CVE-2020-12114)\n\n - A flaw was found in the Linux kernels SELinux LSM hook implementation before version 5.7, where it incorrectly assumed that an skb would only contain a single netlink message. The hook would incorrectly only validate the first netlink message in the skb and allow or deny the rest of the messages within the skb with the granted permission without further processing. (CVE-2020-10751)\n\n - An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3. An attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations before the required authentication process has completed. This could lead to different denial-of-service scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already existing clients in other nearby APs of the same wireless infrastructure. An attacker can forge Authentication and Association Request packets to trigger this vulnerability. (CVE-2019-5108)\n\n - An issue was discovered in write_tpt_entry in drivers/infiniband/hw/cxgb4/mem.c in the Linux kernel through 5.3.2. The cxgb4 driver is directly calling dma_map_single (a DMA function) from a stack variable.\n This could allow an attacker to trigger a Denial of Service, exploitable if this driver is used on an architecture for which this stack/DMA interaction has security relevance. (CVE-2019-17075)\n\n - An issue was discovered in the Linux kernel before 5.1.8. There is a NULL pointer dereference caused by a malicious USB device in the drivers/media/usb/siano/smsusb.c driver. (CVE-2019-15218)\n\n - A memory leak in the gs_can_open() function in drivers/net/can/usb/gs_usb.c in the Linux kernel before 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering usb_submit_urb() failures, aka CID-fb5be6a7b486. (CVE-2019-19052)\n\n - Two memory leaks in the rtl_usb_probe() function in drivers/net/wireless/realtek/rtlwifi/usb.c in the Linux kernel through 5.3.11 allow attackers to cause a denial of service (memory consumption), aka CID-3f9361695113. (CVE-2019-19063)\n\n - A memory leak in the bfad_im_get_stats() function in drivers/scsi/bfa/bfad_attr.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering bfa_port_get_stats() failures, aka CID-0e62395da2bd. (CVE-2019-19066)\n\n - A memory leak in the ath10k_usb_hif_tx_sg() function in drivers/net/wireless/ath/ath10k/usb.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering usb_submit_urb() failures, aka CID-b8d17e7d93d2. (CVE-2019-19078)\n\n - An issue was discovered in the Linux kernel through 5.6.11. btree_gc_coalesce in drivers/md/bcache/btree.c has a deadlock if a coalescing operation fails.

NFS41+ shares mounted in different network\n namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after-\n free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system\n panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out. (CVE-2018-16884)\n\n - An infinite loop issue was found in the vhost_net kernel module in Linux Kernel up to and including\n v5.1-rc6, while handling incoming packets in handle_rx(). It could occur if one end sends packets faster\n than the other end can process them. A guest user, maybe remote one, could use this flaw to stall the\n vhost_net kernel thread, resulting in a DoS scenario. (CVE-2019-3900)\n\n - The Linux kernel before 5.1-rc5 allows page->_refcount reference count overflow, with resultant use-after-\n free issues, if about 140 GiB of RAM exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c,\n include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can\n occur with FUSE requests. (CVE-2019-11487)\n\n - In the Linux kernel before 5.1.7, a device can be tracked by an attacker using the IP ID values the kernel\n produces for connection-less protocols (e.g., UDP and ICMP). When such traffic is sent to multiple\n destination IP addresses, it is possible to obtain hash collisions (of indices to the counter array) and\n thereby obtain the hashing key (via enumeration). An attack may be conducted by hosting a crafted web page\n that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses. (CVE-2019-10638)\n\n - The SCTP socket buffer used by a userspace application is not accounted by the cgroups subsystem. An\n attacker can use this flaw to cause a denial of service attack. Kernel 3.10.x and 4.18.x branches are\n believed to be vulnerable. (CVE-2019-3874)\n\n - The fix for CVE-2019-11599, affecting the Linux kernel before 5.0.10 was not complete. A local user could\n use this flaw to obtain sensitive information, cause a denial of service, or possibly have other\n unspecified impacts by triggering a race condition with mmget_not_zero or get_task_mm calls.\n (CVE-2019-14898)\n\n - In the Linux kernel through 5.3.2, cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c does not reject a\n long SSID IE, leading to a Buffer Overflow. (CVE-2019-17133)\n\n - An issue was discovered in net/wireless/nl80211.c in the Linux kernel through 5.2.17. It does not check\n the length of variable elements in a beacon head, leading to a buffer overflow. (CVE-2019-16746)\n\n - The Linux kernel 4.x (starting from 4.1) and 5.x before 5.0.8 allows Information Exposure (partial kernel\n address disclosure), leading to a KASLR bypass. Specifically, it is possible to extract the KASLR kernel\n image offset using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and\n ICMP). When such traffic is sent to multiple destination IP addresses, it is possible to obtain hash\n collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This\n key contains enough bits from a kernel address (of a static variable) so when the key is extracted (via\n enumeration), the offset of the kernel image is exposed. This attack can be carried out remotely, by the\n attacker forcing the target device to send UDP or ICMP (or certain other) traffic to attacker-controlled\n IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server. ICMP traffic\n is trivial if the server answers ICMP Echo requests (ping). For client targets, if the target visits the\n attacker's web page, then WebRTC or gQUIC can be used to force UDP traffic to attacker-controlled IP\n addresses. NOTE: this attack against KASLR became viable in 4.1 because IP ID generation was changed to\n have a dependency on an address associated with a network namespace. (CVE-2019-10639)\n\n - Memory leaks in drivers/net/wireless/ath/ath9k/htc_hst.c in the Linux kernel through 5.3.11 allow\n attackers to cause a denial of service (memory consumption) by triggering wait_for_completion_timeout()\n failures. This affects the htc_config_pipe_credits() function, the htc_setup_complete() function, and the\n htc_connect_service() function, aka CID-853acf7caf10. (CVE-2019-19073)\n\n - A memory leak in the ath9k_wmi_cmd() function in drivers/net/wireless/ath/ath9k/wmi.c in the Linux kernel\n through 5.3.11 allows attackers to cause a denial of service (memory consumption), aka CID-728c1e2a05e4.\n (CVE-2019-19074)\n\n - kernel/sched/fair.c in the Linux kernel before 5.3.9, when cpu.cfs_quota_us is used (e.g., with\n Kubernetes), allows attackers to cause a denial of service against non-cpu-bound applications by\n generating a workload that triggers unwanted slice expiration, aka CID-de53fd7aedb1. (In other words,\n although this slice expiration would typically be seen with benign workloads, it is possible that an\n attacker could calculate how many stray requests are required to force an entire Kubernetes cluster into a\n low-performance state caused by slice expiration, and ensure that a DDoS attack sent that number of stray\n requests. An attack does not affect the stability of the kernel; it only causes mismanagement of\n application execution.) (CVE-2019-19922)\n\n - A flaw was found in the Linux kernel before 5.8-rc1 in the implementation of the Enhanced IBPB (Indirect\n Branch Prediction Barrier). The IBPB mitigation will be disabled when STIBP is not available or when the\n Enhanced Indirect Branch Restricted Speculation (IBRS) is available. This flaw allows a local attacker to\n perform a Spectre V2 style attack when this configuration is active. The highest threat from this\n vulnerability is to confidentiality. (CVE-2020-10767)\n\n - In the Linux kernel before 5.2.9, there is an info-leak bug that can be caused by a malicious USB device\n in the drivers/net/can/usb/peak_usb/pcan_usb_fd.c driver, aka CID-30a8beeb3042. (CVE-2019-19535)\n\n - An issue was discovered in the Linux kernel before 5.4.7. The prb_calc_retire_blk_tmo() function in\n net/packet/af_packet.c can result in a denial of service (CPU consumption and soft lockup) in a certain\n failure case involving TPACKET_V3, aka CID-b43d1f9f7067.

"description": "According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :\n\n - The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel handles the basic functions of the operating system:\n memory allocation, process allocation, device input and output, etc.Security Fix(es):A flaw was found in the Linux kernel's implementation of the invert video code on VGA consoles when a local attacker attempts to resize the console, calling an ioctl VT_RESIZE, which causes an out-of-bounds write to occur. This flaw allows a local user with access to the VGA console to crash the system, potentially escalating their privileges on the system. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.(CVE-2020-14331)A flaw was found in the HDLC_PPP module of the Linux kernel in versions before 5.9-rc7. Memory corruption and a read overflow is caused by improper input validation in the ppp_cp_parse_cr function which can cause the system to crash or cause a denial of service. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.(CVE-2020-25643)A memory out-of-bounds read flaw was found in the Linux kernel before 5.9-rc2 with the ext3/ext4 file system, in the way it accesses a directory with broken indexing. This flaw allows a local user to crash the system if the directory exists.\n The highest threat from this vulnerability is to system availability.(CVE-2020-14314)A TOCTOU mismatch in the NFS client code in the Linux kernel before 5.8.3 could be used by local attackers to corrupt memory or possibly have unspecified other impact because a size check is in fs/ nfs/ nfs4proc.c instead of fs/ nfs/ nfs4xdr.c, aka CID-b4487b935452.(CVE-2020-25212)The rbd block device driver in drivers/block/rbd.c in the Linux kernel through 5.8.9 used incomplete permission checking for access to rbd devices, which could be leveraged by local attackers to map or unmap rbd block devices, aka CID-f44d04e696fe.(CVE-2020-25284)A race condition between hugetlb sysctl handlers in mm/hugetlb.c in the Linux kernel before 5.8.8 could be used by local attackers to corrupt memory, cause a NULL pointer dereference, or possibly have unspecified other impact, aka CID-17743798d812.(CVE-2020-25285)A flaw was found in the Linux kernel before 5.9-rc4. Memory corruption can be exploited to gain root privileges from unprivileged processes. The highest threat from this vulnerability is to data confidentiality and integrity.(CVE-2020-14386)In the Linux kernel through 5.8.7, local attackers able to inject conntrack netlink configuration could overflow a local buffer, causing crashes or triggering use of incorrect protocol numbers in ctnetlink_parse_tuple_filter in net/ netfilter/ nf_conntrack_netlink.c, aka CID-1cc5ef91d2ff.(CVE-2020-25211)The VFIO PCI driver in the Linux kernel through 5.6.13 mishandles attempts to access disabled memory space.(CVE-2020-12888)The kernel in Red Hat Enterprise Linux 7 and MRG-2 does not clear garbage data for SG_IO buffer, which may leaking sensitive information to userspace.(CVE-2014-8181)A flaw was found in the Linux kernels SELinux LSM hook implementation before version 5.7, where it incorrectly assumed that an skb would only contain a single netlink message. The hook would incorrectly only validate the first netlink message in the skb and allow or deny the rest of the messages within the skb with the granted permission without further processing.(CVE-2020-10751)The Linux kernel through 5.7.11 allows remote attackers to make observations that help to obtain sensitive information about the internal state of the network RNG, aka CID-f227e3ec3b5c. This is related to drivers/char/random.c and kernel/time/timer.c.(CVE-2020-16166)A buffer over-read flaw was found in RH kernel versions before 5.0 in crypto_authenc_extractkeys in crypto/authenc.c in the IPsec Cryptographic algorithm's module, authenc. When a payload longer than 4 bytes, and is not following 4-byte alignment boundary guidelines, it causes a buffer over-read threat, leading to a system crash.\n This flaw allows a local attacker with user privileges to cause a denial of service.(CVE-2020-10769)In the Linux kernel through 5.7.6, usbtest_disconnect in drivers/usb/misc/usbtest.c has a memory leak, aka CID-28ebeb8db770.(CVE-2020-15393)An issue was discovered in the Linux kernel through 5.7.1.\n drivers/tty/vt/keyboard.c has an integer overflow if k_ascii is called several times in a row, aka CID-b86dab054059.(CVE-2020-13974)go7007_snd_init in drivers/media/usb/go7007/snd-go7007.c in the Linux kernel before 5.6 does not call snd_card_free for a failure path, which causes a memory leak, aka CID-9453264ef586.(CVE-2019-20810)An issue was discovered in the Linux kernel before 5.0.6. In rx_queue_add_kobject() and netdev_queue_add_kobject() in net/core/ net-sysfs.c, a reference count is mishandled, aka CID-a3e23f719f5c.(CVE-2019-20811)An issue was discovered in the Linux kernel before 5.4.7.\n The prb_calc_retire_blk_tmo() function in net/packet/af_packet.c can result in a denial of service (CPU consumption and soft lockup) in a certain failure case involving TPACKET_V3, aka CID-b43d1f9f7067.(CVE-2019-20812)A flaw was found in the Linux kernel's implementation of Userspace core dumps. This flaw allows an attacker with a local account to crash a trivial program and exfiltrate private kernel data.(CVE-2020-10732)\n\nNote that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.

This high resolution timer(hrtimer)\nruns when a L2 guest is active. After VM exit, the sync_vmcs12() timer\nobject is stopped. The use-after-free occurs if the timer object is\nfreed before calling sync_vmcs12() routine.

While creating a\ndevice via kvm_ioctl_create_device(), the device holds a reference to\na VM object, later this reference is transferred to the caller's file\ndescriptor table. If such file descriptor was to be closed, reference\ncount to the VM object could become zero, potentially leading to a\nuse-after-free issue. A user/process could use this flaw to crash the\nguest VM resulting in a denial of service issue or, potentially, gain\nprivileged access to a system.

"2023-05-29T14:24:50", "description": "The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2020-5885 advisory.\n\n - The SCTP socket buffer used by a userspace application is not accounted by the cgroups subsystem. An attacker can use this flaw to cause a denial of service attack. Kernel 3.10.x and 4.18.x branches are believed to be vulnerable. (CVE-2019-3874)\n\n - A flaw was found in the Linux kernel before 5.8-rc1 in the implementation of the Enhanced IBPB (Indirect Branch Prediction Barrier). The IBPB mitigation will be disabled when STIBP is not available or when the Enhanced Indirect Branch Restricted Speculation (IBRS) is available. This flaw allows a local attacker to perform a Spectre V2 style attack when this configuration is active. The highest threat from this vulnerability is to confidentiality. (CVE-2020-10767)\n\n - A flaw was found in the Linux kernels implementation of the invert video code on VGA consoles when a local attacker attempts to resize the console, calling an ioctl VT_RESIZE, which causes an out-of-bounds write to occur. This flaw allows a local user with access to the VGA console to crash the system, potentially escalating their privileges on the system. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2020-14331)\n\n - fs/btrfs/volumes.c in the Linux kernel before 5.1 allows a btrfs_verify_dev_extents NULL pointer dereference via a crafted btrfs image because fs_devices->devices is mishandled within find_device, aka CID-09ba3bc9dd15. (CVE-2019-18885)\n\n - In the Linux kernel before 5.7.8, fs/nfsd/vfs.c (in the NFS server) can set incorrect permissions on new filesystem objects when the filesystem lacks ACL support, aka CID-22cf8419f131. This occurs because the current umask is not considered. (CVE-2020-24394)\n\n - A flaw was found in the Linux Kernel before 5.8-rc6 in the ZRAM kernel module, where a user with a local account and the ability to read the /sys/class/zram-control/hot_add file can create ZRAM device nodes in the /dev/ directory. This read allocates kernel memory and is not accounted for a user that triggers the creation of that ZRAM device. With this vulnerability, continually reading the device may consume a large amount of system memory and cause the Out-of-Memory (OOM) killer to activate and terminate random userspace processes, possibly making the system inoperable. (CVE-2020-10781)\n\n - The Linux kernel through 5.7.11 allows remote attackers to make observations that help to obtain sensitive information about the internal state of the network RNG, aka CID-f227e3ec3b5c. This is related to drivers/char/random.c and kernel/time/timer.c. (CVE-2020-16166)\n\n - An issue where a provided address with access_ok() is not checked was discovered in i915_gem_execbuffer2_ioctl in drivers/gpu/drm/i915/i915_gem_execbuffer.c in the Linux kernel through 4.19.13. A local attacker can craft a malicious IOCTL function call to overwrite arbitrary kernel memory, resulting in a Denial of Service or privilege escalation. (CVE-2018-20669)\n\n - A flaw was found in the Linux kernel before 5.9-rc4. Memory corruption can be exploited to gain root privileges from unprivileged processes. The highest threat from this vulnerability is to data confidentiality and integrity. (CVE-2020-14386)\n\n - A memory out-of-bounds read flaw was found in the Linux kernel before 5.9-rc2 with the ext3/ext4 file system, in the way it accesses a directory with broken indexing. This flaw allows a local user to crash the system if the directory exists. The highest threat from this vulnerability is to system availability.\n (CVE-2020-14314)\n\n - A TOCTOU mismatch in the NFS client code in the Linux kernel before 5.8.3 could be used by local attackers to corrupt memory or possibly have unspecified other impact because a size check is in fs/nfs/nfs4proc.c instead of fs/nfs/nfs4xdr.c, aka CID-b4487b935452. (CVE-2020-25212)\n\n - The rbd block device driver in drivers/block/rbd.c in the Linux kernel through 5.8.9 used incomplete permission checking for access to rbd devices, which could be leveraged by local attackers to map or unmap rbd block devices, aka CID-f44d04e696fe. (CVE-2020-25284)\n\n - A race condition between hugetlb sysctl handlers in mm/hugetlb.c in the Linux kernel before 5.8.8 could be used by local attackers to corrupt memory, cause a NULL pointer dereference, or possibly have unspecified other impact, aka CID-17743798d812.

(CVE-2020-25212)\n\n - The rbd block device driver in drivers/block/rbd.c in the Linux kernel through 5.8.9 used incomplete\n permission checking for access to rbd devices, which could be leveraged by local attackers to map or unmap\n rbd block devices, aka CID-f44d04e696fe. (CVE-2020-25284)\n\n - A race condition between hugetlb sysctl handlers in mm/hugetlb.c in the Linux kernel before 5.8.8 could be\n used by local attackers to corrupt memory, cause a NULL pointer dereference, or possibly have unspecified\n other impact, aka CID-17743798d812. (CVE-2020-25285)\n\n - A flaw was found in the Linux kernel's implementation of biovecs in versions before 5.9-rc7. A zero-length\n biovec request issued by the block subsystem could cause the kernel to enter an infinite loop, causing a\n denial of service. This flaw allows a local attacker with basic privileges to issue requests to a block\n device, resulting in a denial of service. The highest threat from this vulnerability is to system\n availability. (CVE-2020-25641)\n\n - A flaw was found in the HDLC_PPP module of the Linux kernel in versions before 5.9-rc7. Memory corruption\n and a read overflow is caused by improper input validation in the ppp_cp_parse_cr function which can cause\n the system to crash or cause a denial of service. The highest threat from this vulnerability is to data\n confidentiality and integrity as well as system availability. (CVE-2020-25643)\n\n - A flaw was found in the Linux kernel in versions before 5.9-rc7. Traffic between two Geneve endpoints may\n be unencrypted when IPsec is configured to encrypt traffic for the specific UDP port used by the GENEVE\n tunnel allowing anyone between the two endpoints to read the traffic unencrypted. The main threat from\n this vulnerability is to data confidentiality. (CVE-2020-25645)\n\n - A missing CAP_NET_RAW check in NFC socket creation in net/nfc/rawsock.c in the Linux kernel before 5.8.2\n could be used by local attackers to create raw sockets, bypassing security mechanisms, aka\n CID-26896f01467a. (CVE-2020-26088)\n\nNote that Nessus has not tested for this issue but has instead relied only on the application's self-reported version\nnumber.\");\n script_set_attribute(attribute:\"see_also\",
