The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6896-3 advisory.

    It was discovered that the ATA over Ethernet (AoE) driver in the Linux kernel contained a race condition,     leading to a use-after-free vulnerability. An attacker could use this to cause a denial of service or     possibly execute arbitrary code. (CVE-2023-6270)

    It was discovered that the Atheros 802.11ac wireless driver did not properly validate certain data     structures, leading to a NULL pointer dereference. An attacker could possibly use this to cause a denial     of service. (CVE-2023-7042)

    Yuxuan Hu discovered that the Bluetooth RFCOMM protocol driver in the Linux Kernel contained a race     condition, leading to a NULL pointer dereference. An attacker could possibly use this to cause a denial of     service (system crash). (CVE-2024-22099)

    Gui-Dong Han discovered that the software RAID driver in the Linux kernel contained a race condition,     leading to an integer overflow vulnerability. A privileged attacker could possibly use this to cause a     denial of service (system crash). (CVE-2024-23307)

    It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel when     modifying certain settings values through debugfs. A privileged local attacker could use this to cause a     denial of service. (CVE-2024-24857, CVE-2024-24858, CVE-2024-24859)

    Bai Jiaju discovered that the Xceive XC4000 silicon tuner device driver in the Linux kernel contained a     race condition, leading to an integer overflow vulnerability. An attacker could possibly use this to cause     a denial of service (system crash). (CVE-2024-24861)

    Chenyuan Yang discovered that the Unsorted Block Images (UBI) flash device volume management subsystem did     not properly validate logical eraseblock sizes in certain situations. An attacker could possibly use this     to cause a denial of service (system crash). (CVE-2024-25739)

    uio: Fix use-after-free in uio_open(CVE-2023-52439)

    A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation.The nft_verdict_init() function allows positive values as drop error     within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when     NF_DROP is issued with a drop error which resembles NF_ACCEPT.(CVE-2024-1086)

    The IPv6 implementation in the Linux kernel before 6.3 has a net/ipv6/route.c max_size threshold that can     be consumed easily, e.g., leading to a denial of service (network is unreachable errors) when IPv6 packets     are sent in a loop via a raw socket.(CVE-2023-52340)

    net: usb: smsc75xx: Fix uninit-value access in __smsc75xx_read_reg(CVE-2023-52528)

    A race condition was found in the Linux kernel's scsi device driver in lpfc_unregister_fcf_rescan()     function. This can result in a null pointer dereference issue, possibly leading to a kernel panic or     denial of service issue.(CVE-2024-24855)

    A use-after-free flaw was found in the __ext4_remount in fs/ext4/super.c in ext4 in the Linux kernel. This     flaw allows a local user to cause an information leak problem while freeing the old quota file names     before a potential failure, leading to a use-after-free.(CVE-2024-0775)

    Integer Overflow or Wraparound vulnerability in openEuler kernel on Linux (filesystem modules) allows     Forced Integer Overflow.This issue affects openEuler kernel: from 4.19.90 before 4.19.90-2401.3, from     5.10.0-60.18.0 before 5.10.0-183.0.0.(CVE-2021-33631)

    dm rq: fix double free of blk_mq_tag_set in dev remove after table load fails(CVE-2021-46938)

    NFS: Don't corrupt the value of pg_bytes_written in nfs_do_recoalesce()(CVE-2021-47166)

    drm: Don't unref the same fb many times by mistake due to deadlock handling(CVE-2023-52486)

    A flaw was found in the Netfilter subsystem in the Linux kernel. The issue is in the nft_byteorder_eval()     function, where the code iterates through a loop and writes to the `dst` array. On each iteration, 8 bytes     are written, but `dst` is an array of u32, so each element only has space for 4 bytes. That means every     iteration overwrites part of the previous element corrupting this array of u32. This flaw allows a local     user to cause a denial of service or potentially break NetFilter functionality.(CVE-2024-0607)

    blk-mq: fix IO hang from sbitmap wakeup race(CVE-2024-26671)

    i2c: Fix a potential use after free(CVE-2019-25162)

    bus: qcom: Put child node before return(CVE-2021-47054)

    A vulnerability was reported in the Open vSwitch sub-component in the Linux Kernel. The flaw occurs when a     recursive operation of code push recursively calls into the code block. The OVS module does not validate     the stack depth, pushing too many frames and causing a stack overflow. As a result, this can lead to a     crash or other related issues.(CVE-2024-1151)
