The version of kernel installed on the remote host is prior to 5.10.68-62.173. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2022-006 advisory.

  - Use-after-free vulnerability in the Linux kernel exploitable by a local attacker due to reuse of a DCCP     socket with an attached dccps_hc_tx_ccid object as a listener after being released. Fixed in Ubuntu Linux     kernel 5.4.0-51.56, 5.3.0-68.63, 4.15.0-121.123, 4.4.0-193.224, 3.13.0.182.191 and 3.2.0-149.196.
    (CVE-2020-16119)

  - A flaw in the processing of received ICMP errors (ICMP fragment needed and ICMP redirect) in the Linux     kernel functionality was found to allow the ability to quickly scan open UDP ports. This flaw allows an     off-path remote user to effectively bypass the source port UDP randomization. The highest threat from this     vulnerability is to confidentiality and possibly integrity, because software that relies on UDP source     port randomization are indirectly affected as well. (CVE-2021-20322)

  - loop_rw_iter in fs/io_uring.c in the Linux kernel 5.10 through 5.14.6 allows local users to gain     privileges by using IORING_OP_PROVIDE_BUFFERS to trigger a free of a kernel buffer, as demonstrated by     using /proc/<pid>/maps for exploitation. (CVE-2021-41073)

  - In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables: clone set element     expression template memcpy() breaks when using connlimit in set elements. Use nft_expr_clone() to     initialize the connlimit expression list, otherwise connlimit garbage collector crashes when walking on     the list head copy.

  - In ip_check_mc_rcu of igmp.c, there is a possible use after free due to improper locking. This could lead     to local escalation of privilege when opening and closing inet sockets with no additional execution     privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android     kernelAndroid ID: A-112551163References: Upstream kernel (CVE-2022-20141)
