The remote Ubuntu 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5911-1 advisory.
A flaw was found in the Linux kernel. A denial of service flaw may occur if there is a consecutive request of the NVME_IOCTL_RESET and the NVME_IOCTL_SUBSYS_RESET through the device file of the driver, resulting in a PCIe link disconnect. (CVE-2022-3169)
A flaw was found in the KVM’s AMD nested virtualization (SVM). A malicious L1 guest could purposely fail to intercept the shutdown of a cooperative nested guest (L2), possibly leading to a page fault and kernel panic in the host (L0). (CVE-2022-3344)
A vulnerability classified as problematic has been found in Linux Kernel. This affects the function fib_nh_match of the file net/ipv4/fib_semantics.c of the component IPv4 Handler. The manipulation leads to out-of-bounds read. It is possible to initiate the attack remotely. It is recommended to apply a patch to fix this issue. The identifier VDB-210357 was assigned to this vulnerability. (CVE-2022-3435)
A vulnerability has been found in Linux Kernel and classified as problematic. This vulnerability affects the function kcm_tx_work of the file net/kcm/kcmsock.c of the component kcm. The manipulation leads to race condition. It is recommended to apply a patch to fix this issue. VDB-211018 is the identifier assigned to this vulnerability. (CVE-2022-3521)
A vulnerability has been found in Linux Kernel and classified as critical. Affected by this vulnerability is the function area_cache_get of the file drivers/net/ethernet/netronome/nfp/nfpcore/nfp_cppcore.c of the component IPsec. The manipulation leads to use after free. It is recommended to apply a patch to fix this issue. The identifier VDB-211045 was assigned to this vulnerability. (CVE-2022-3545)
An incorrect TLB flush issue was found in the Linux kernel’s GPU i915 kernel driver, potentially leading to random memory corruption or data leaks. This flaw could allow a local user to crash the system or escalate their privileges on the system. (CVE-2022-4139)
A use-after-free vulnerability was found in __nfs42_ssc_open() in fs/nfs/nfs4file.c in the Linux kernel.
This flaw allows an attacker to conduct a remote denial (CVE-2022-4379)
A race condition in the x86 KVM subsystem in the Linux kernel through 6.1-rc6 allows guest OS users to cause a denial of service (host OS crash or host OS memory corruption) when nested virtualisation and the TDP MMU are enabled. (CVE-2022-45869)
An issue was discovered in the Linux kernel before 6.0.11. Missing validation of the number of channels in drivers/net/wireless/microchip/wilc1000/cfg80211.c in the WILC1000 wireless driver can trigger a heap- based buffer overflow when copying the list of operating channels from Wi-Fi management frames.
(CVE-2022-47518)
An issue was discovered in the Linux kernel before 6.0.11. Missing validation of IEEE80211_P2P_ATTR_OPER_CHANNEL in drivers/net/wireless/microchip/wilc1000/cfg80211.c in the WILC1000 wireless driver can trigger an out-of-bounds write when parsing the channel list attribute from Wi-Fi management frames. (CVE-2022-47519)
An issue was discovered in the Linux kernel before 6.0.11. Missing offset validation in drivers/net/wireless/microchip/wilc1000/hif.c in the WILC1000 wireless driver can trigger an out-of-bounds read when parsing a Robust Security Network (RSN) information element from a Netlink packet.
(CVE-2022-47520)
An issue was discovered in the Linux kernel before 6.0.11. Missing validation of IEEE80211_P2P_ATTR_CHANNEL_LIST in drivers/net/wireless/microchip/wilc1000/cfg80211.c in the WILC1000 wireless driver can trigger a heap-based buffer overflow when parsing the operating channel attribute from Wi-Fi management frames. (CVE-2022-47521)
A buffer overflow vulnerability was found in the Netfilter subsystem in the Linux Kernel. This issue could allow the leakage of both stack and heap addresses, and potentially allow Local Privilege Escalation to the root user via arbitrary code execution. (CVE-2023-0179)
There is a use-after-free vulnerability in the Linux Kernel which can be exploited to achieve local privilege escalation. To reach the vulnerability kernel configuration flag CONFIG_TLS or CONFIG_XFRM_ESPINTCP has to be configured, but the operation does not require any privilege. There is a use-after-free bug of icsk_ulp_data of a struct inet_connection_sock. When CONFIG_TLS is enabled, user can install a tls context (struct tls_context) on a connected tcp socket. The context is not cleared if this socket is disconnected and reused as a listener. If a new socket is created from the listener, the context is inherited and vulnerable. The setsockopt TCP_ULP operation does not require any privilege. We recommend upgrading past commit 2c02d41d71f90a5168391b6a5f2954112ba2307c (CVE-2023-0461)
In the Linux kernel 6.0.8, there is a use-after-free in inode_cgwb_move_to_attached in fs/fs-writeback.c, related to __list_del_entry_valid. (CVE-2023-26605)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
