The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2021:4140 advisory.

  - Improper access control in BlueZ may allow an authenticated user to potentially enable information     disclosure via adjacent access. (CVE-2021-0129)

  - A use-after-free in function hci_sock_bound_ioctl() of the Linux kernel HCI subsystem was found in the way     user calls ioct HCIUNBLOCKADDR or other way triggers race condition of the call hci_unregister_dev()     together with one of the calls hci_sock_blacklist_add(), hci_sock_blacklist_del(), hci_get_conn_info(),     hci_get_auth_info(). A privileged local user could use this flaw to crash the system or escalate their     privileges on the system. This flaw affects the Linux kernel versions prior to 5.13-rc5. (CVE-2021-3573)

  - A flaw was found in the Linux kernel netfilter implementation in versions prior to 5.5-rc7. A user with     root (CAP_SYS_ADMIN) access is able to panic the system when issuing netfilter netflow commands.
    (CVE-2021-3635)

  - An issue was discovered in fs/fuse/fuse_i.h in the Linux kernel before 5.11.8. A stall on CPU can occur     because a retry loop continually finds the same bad inode, aka CID-775c5033a0d1. (CVE-2021-28950)

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

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

  - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent     Privacy (WEP) doesn't require that received fragments be cleared from memory after (re)connecting to a     network. Under the right circumstances, when another device sends fragmented frames encrypted using WEP,     CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.
    (CVE-2020-24586)

  - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent     Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary     can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP,     CCMP, or GCMP encryption key is periodically renewed. (CVE-2020-24587)

  - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent     Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated.
    Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an     adversary can abuse this to inject arbitrary network packets. (CVE-2020-24588)

  - A vulnerability was found in Linux kernel where non-blocking socket in llcp_sock_connect() leads to leak     and eventually hanging-up the system. (CVE-2020-25673)

  - The vgacon subsystem in the Linux kernel before 5.8.10 mishandles software scrollback. There is a     vgacon_scrolldelta out-of-bounds read, aka CID-973c096f6a85. (CVE-2020-28097)

  - An issue was discovered in the Linux kernel before 5.10. drivers/infiniband/core/ucma.c has a use-after-     free because the ctx is reached via the ctx_list in some ucma_migrate_id situations where ucma_close is     called, aka CID-f5449e74802c. (CVE-2020-36385)

  - An issue was discovered in the Linux kernel before 5.8.1. net/bluetooth/hci_event.c has a slab out-of-     bounds read in hci_extended_inquiry_result_evt, aka CID-51c19bf3d5cf. (CVE-2020-36386)

  - In __hidinput_change_resolution_multipliers of hid-input.c, there is a possible out of bounds write due to     a heap buffer overflow. 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-173843328References: Upstream kernel (CVE-2021-0512)

  - In pfkey_dump of af_key.c, there is a possible out-of-bounds read due to a missing bounds check. This     could lead to local information disclosure in the kernel with System execution privileges needed. User     interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-110373476     (CVE-2021-0605)

  - A heap out-of-bounds write affecting Linux since v2.6.19-rc1 was discovered in net/netfilter/x_tables.c.
    This allows an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name     space (CVE-2021-22555)

  - In kernel/bpf/verifier.c in the Linux kernel before 5.12.13, a branch can be mispredicted (e.g., because     of type confusion) and consequently an unprivileged BPF program can read arbitrary memory locations via a     side-channel attack, aka CID-9183671af6db. (CVE-2021-33624)

  - net/can/bcm.c in the Linux kernel through 5.12.10 allows local users to obtain sensitive information from     kernel stack memory because parts of a data structure are uninitialized. (CVE-2021-34693)

  - A flaw double-free memory corruption in the Linux kernel HCI device initialization subsystem was found in     the way user attach malicious HCI TTY Bluetooth device. A local user could use this flaw to crash the     system. This flaw affects all the Linux kernel versions starting from 3.13. (CVE-2021-3564)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-001520 advisory.

    It was discovered that the eBPF implementation in the Linux kernel did not properly track bounds     information for 32 bit registers when performing div and mod operations. A local attacker could use this     to possibly execute arbitrary code.
