The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2020-5913 advisory.

  - In the Linux kernel 5.0.21, mounting a crafted btrfs filesystem image, performing some operations, and     unmounting can lead to a use-after-free in btrfs_queue_work in fs/btrfs/async-thread.c. (CVE-2019-19377)

  - A flaw null pointer dereference in the Linux kernel cgroupv2 subsystem in versions before 5.7.10 was found     in the way when reboot the system. A local user could use this flaw to crash the system or escalate their     privileges on the system. (CVE-2020-14356)

  - A flaw was found in the Linux kernel before 5.9-rc4. A failure of the file system metadata validator in     XFS can cause an inode with a valid, user-creatable extended attribute to be flagged as corrupt. This can     lead to the filesystem being shutdown, or otherwise rendered inaccessible until it is remounted, leading     to a denial of service. The highest threat from this vulnerability is to system availability.
    (CVE-2020-14385)

  - 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)

  - 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)

  - The Linux kernel through 5.8.13 does not properly enforce the Secure Boot Forbidden Signature Database     (aka dbx) protection mechanism. This affects certs/blacklist.c and certs/system_keyring.c.
    (CVE-2020-26541)

  - Insufficient access control in the Linux kernel driver for some Intel(R) Processors may allow an     authenticated user to potentially enable information disclosure via local access. (CVE-2020-8694)

  - Observable discrepancy in the RAPL interface for some Intel(R) Processors may allow a privileged user to     potentially enable information disclosure via local access. (CVE-2020-8695)

  - An issue was discovered in the Linux kernel through 5.2.13. nbd_genl_status in drivers/block/nbd.c does     not check the nla_nest_start_noflag return value. (CVE-2019-16089)

  - A flaw was found in the Linux kernel in versions before 5.9-rc6. When changing screen size, an out-of-     bounds memory write can occur leading to memory corruption or a denial of service. Due to the nature of     the flaw, privilege escalation cannot be fully ruled out. (CVE-2020-14390)

  - A flaw was found in the Linux kernel in versions before 5.9-rc7. Traffic between two Geneve endpoints may     be unencrypted when IPsec is configured to encrypt traffic for the specific UDP port used by the GENEVE     tunnel allowing anyone between the two endpoints to read the traffic unencrypted. The main threat from     this vulnerability is to data confidentiality. (CVE-2020-25645)

  - **DISPUTED** An issue was discovered in the efi subsystem in the Linux kernel through 5.1.5.
    phys_efi_set_virtual_address_map in arch/x86/platform/efi/efi.c and efi_call_phys_prolog in     arch/x86/platform/efi/efi_64.c mishandle memory allocation failures. NOTE: This id is disputed as not     being an issue because All the code touched by the referenced commit runs only at boot, before any user     processes are started. Therefore, there is no possibility for an unprivileged user to control it..
    (CVE-2019-12380)

  - In the Linux kernel 5.0.21 and 5.3.11, mounting a crafted btrfs filesystem image, performing some     operations, and then making a syncfs system call can lead to a use-after-free in try_merge_free_space in     fs/btrfs/free-space-cache.c because the pointer to a left data structure can be the same as the pointer to     a right data structure. (CVE-2019-19448)

  - A flaw was found in the Linux kernel's implementation of biovecs in versions before 5.9-rc7. A zero-length     biovec request issued by the block subsystem could cause the kernel to enter an infinite loop, causing a     denial of service. This flaw allows a local attacker with basic privileges to issue requests to a block     device, resulting in a denial of service. The highest threat from this vulnerability is to system     availability. (CVE-2020-25641)

  - btrfs_root_node in fs/btrfs/ctree.c in the Linux kernel through 5.3.12 allows a NULL pointer dereference     because rcu_dereference(root->node) can be zero. (CVE-2019-19036)

  - __btrfs_free_extent in fs/btrfs/extent-tree.c in the Linux kernel through 5.3.12 calls btrfs_print_leaf in     a certain ENOENT case, which allows local users to obtain potentially sensitive information about register     values via the dmesg program. NOTE: The BTRFS development team disputes this issues as not being a     vulnerability because 1) The kernel provide facilities to restrict access to dmesg - dmesg_restrict=1     sysctl option. So it's really up to the system administrator to judge whether dmesg access shall be     disallowed or not. 2) WARN/WARN_ON are widely used macros in the linux kernel. If this CVE is considered     valid this would mean there are literally thousands CVE lurking in the kernel - something which clearly is     not the case. (CVE-2019-19039)

  - In the Linux kernel 5.3.11, mounting a crafted btrfs image twice can cause an rwsem_down_write_slowpath     use-after-free because (in rwsem_can_spin_on_owner in kernel/locking/rwsem.c) rwsem_owner_flags returns an     already freed pointer, (CVE-2019-19318)

  - In the Linux kernel 5.0.21, mounting a crafted btrfs filesystem image, performing some operations, and     unmounting can lead to a use-after-free in btrfs_queue_work in fs/btrfs/async-thread.c. (CVE-2019-19377)

  - In the Linux kernel 5.0.21, mounting a crafted btrfs filesystem image, performing some operations, and     then making a syncfs system call can lead to a use-after-free in __mutex_lock in kernel/locking/mutex.c.
    This is related to mutex_can_spin_on_owner in kernel/locking/mutex.c, __btrfs_qgroup_free_meta in     fs/btrfs/qgroup.c, and btrfs_insert_delayed_items in fs/btrfs/delayed-inode.c. (CVE-2019-19813)

  - In the Linux kernel 5.0.21, mounting a crafted btrfs filesystem image and performing some operations can     cause slab-out-of-bounds write access in __btrfs_map_block in fs/btrfs/volumes.c, because a value of 1 for     the number of data stripes is mishandled. (CVE-2019-19816)

  - A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7.
    This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into     the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO     restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate     that the category bitmap is present, even if it has not been allocated. This issue leads to a NULL pointer     dereference issue while importing the same category bitmap into SELinux. This flaw allows a remote network     user to crash the system kernel, resulting in a denial of service. (CVE-2020-10711)

  - An issue was discovered in the Linux kernel through 5.6.11. sg_write lacks an sg_remove_request call in a     certain failure case, aka CID-83c6f2390040. (CVE-2020-12770)

  - gadget_dev_desc_UDC_store in drivers/usb/gadget/configfs.c in the Linux kernel 3.16 through 5.6.13 relies     on kstrdup without considering the possibility of an internal '\0' value, which allows attackers to     trigger an out-of-bounds read, aka CID-15753588bcd4. (CVE-2020-13143)
