The remote Ubuntu 18.04 LTS / 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5756-1 advisory.
A vulnerability was found in Linux Kernel. It has been declared as problematic. Affected by this vulnerability is the function ipv6_renew_options of the component IPv6 Handler. The manipulation leads to memory leak. The attack can be launched remotely. It is recommended to apply a patch to fix this issue.
The identifier VDB-211021 was assigned to this vulnerability. (CVE-2022-3524)
A vulnerability classified as critical was found in Linux Kernel. Affected by this vulnerability is the function l2cap_reassemble_sdu of the file net/bluetooth/l2cap_core.c of the component Bluetooth. The manipulation leads to use after free. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-211087. (CVE-2022-3564)
A vulnerability, which was classified as critical, has been found in Linux Kernel. Affected by this issue is the function del_timer of the file drivers/isdn/mISDN/l1oip_core.c of the component Bluetooth. The manipulation leads to use after free. It is recommended to apply a patch to fix this issue. The identifier of this vulnerability is VDB-211088. (CVE-2022-3565)
A vulnerability, which was classified as problematic, was found in Linux Kernel. This affects the function tcp_getsockopt/tcp_setsockopt of the component TCP Handler. The manipulation leads to race condition. It is recommended to apply a patch to fix this issue. The identifier VDB-211089 was assigned to this vulnerability. (CVE-2022-3566)
A vulnerability has been found in Linux Kernel and classified as problematic. This vulnerability affects the function inet6_stream_ops/inet6_dgram_ops of the component IPv6 Handler. The manipulation leads to race condition. It is recommended to apply a patch to fix this issue. VDB-211090 is the identifier assigned to this vulnerability. (CVE-2022-3567)
A vulnerability was found in Linux Kernel. It has been declared as problematic. Affected by this vulnerability is the function intr_callback of the file drivers/net/usb/r8152.c of the component BPF. The manipulation leads to logging of excessive data. The attack can be launched remotely. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-211363.
(CVE-2022-3594)
A vulnerability was found in Linux Kernel. It has been classified as problematic. Affected is the function nilfs_bmap_lookup_at_level of the file fs/nilfs2/inode.c of the component nilfs2. The manipulation leads to null pointer dereference. It is possible to launch the attack remotely. It is recommended to apply a patch to fix this issue. The identifier of this vulnerability is VDB-211920. (CVE-2022-3621)
mm/rmap.c in the Linux kernel before 5.19.7 has a use-after-free related to leaf anon_vma double reuse.
(CVE-2022-42703)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
