The version of kernel-generic installed on the remote host is prior to 5.15.94 / 5.15.94_smp. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2023-048-01 advisory.

  - 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 critical has been found in Linux Kernel. Affected is the function     btf_dump_name_dups of the file tools/lib/bpf/btf_dump.c of the component libbpf. 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-211032. (CVE-2022-3534)

  - 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 out-of-bounds(OOB) memory access vulnerability was found in vmwgfx driver in     drivers/gpu/vmxgfx/vmxgfx_kms.c in GPU component in the Linux kernel with device file '/dev/dri/renderD128     (or Dxxx)'. This flaw allows a local attacker with a user account on the system to gain privilege, causing     a denial of service(DoS). (CVE-2022-36280)

  - Guests can trigger NIC interface reset/abort/crash via netback It is possible for a guest to trigger a NIC     interface reset/abort/crash in a Linux based network backend by sending certain kinds of packets. It     appears to be an (unwritten?) assumption in the rest of the Linux network stack that packet protocol     headers are all contained within the linear section of the SKB and some NICs behave badly if this is not     the case. This has been reported to occur with Cisco (enic) and Broadcom NetXtrem II BCM5780 (bnx2x)     though it may be an issue with other NICs/drivers as well. In case the frontend is sending requests with     split headers, netback will forward those violating above mentioned assumption to the networking core,     resulting in said misbehavior. (CVE-2022-3643)

  - In drivers/media/dvb-core/dmxdev.c in the Linux kernel through 5.19.10, there is a use-after-free caused     by refcount races, affecting dvb_demux_open and dvb_dmxdev_release. (CVE-2022-41218)

  - A flaw was found in the Linux kernel's Layer 2 Tunneling Protocol (L2TP). A missing lock when clearing     sk_user_data can lead to a race condition and NULL pointer dereference. A local user could use this flaw     to potentially crash the system causing a denial of service. (CVE-2022-4129)

  - A stack overflow flaw was found in the Linux kernel's SYSCTL subsystem in how a user changes certain     kernel parameters and variables. This flaw allows a local user to crash or potentially escalate their     privileges on the system. (CVE-2022-4378)

  - A use-after-free flaw caused by a race among the superblock operations in the gadgetfs Linux driver was     found. It could be triggered by yanking out a device that is running the gadgetfs side. (CVE-2022-4382)

  - 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 through 6.0.10. l2cap_config_req in net/bluetooth/l2cap_core.c     has an integer wraparound via L2CAP_CONF_REQ packets. (CVE-2022-45934)

  - 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)

  - In the Linux kernel before 6.1.6, a NULL pointer dereference bug in the traffic control subsystem allows     an unprivileged user to trigger a denial of service (system crash) via a crafted traffic control     configuration that is set up with tc qdisc and tc class commands. This affects qdisc_graft in     net/sched/sch_api.c. (CVE-2022-47929)

  - A flaw NULL Pointer Dereference in the Linux kernel NTFS3 driver function attr_punch_hole() was found. A     local user could use this flaw to crash the system. (CVE-2022-4842)

  - A use after free vulnerability exists in the ALSA PCM package in the Linux Kernel.
    SNDRV_CTL_IOCTL_ELEM_{READ|WRITE}32 is missing locks that can be used in a use-after-free that can result     in a priviledge escalation to gain ring0 access from the system user. We recommend upgrading past commit     56b88b50565cd8b946a2d00b0c83927b7ebb055e (CVE-2023-0266)

  - A NULL pointer dereference flaw was found in rawv6_push_pending_frames in net/ipv6/raw.c in the network     subcomponent in the Linux kernel. This flaw causes the system to crash. (CVE-2023-0394)

  - cbq_classify in net/sched/sch_cbq.c in the Linux kernel through 6.1.4 allows attackers to cause a denial     of service (slab-out-of-bounds read) because of type confusion (non-negative numbers can sometimes     indicate a TC_ACT_SHOT condition rather than valid classification results). (CVE-2023-23454)

  - atm_tc_enqueue in net/sched/sch_atm.c in the Linux kernel through 6.1.4 allows attackers to cause a denial     of service because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition     rather than valid classification results). (CVE-2023-23455)

  - In rndis_query_oid in drivers/net/wireless/rndis_wlan.c in the Linux kernel through 6.1.5, there is an     integer overflow in an addition. (CVE-2023-23559)

  - In the Linux kernel before 6.1.6, a NULL pointer dereference bug in the traffic control subsystem allows     an unprivileged user to trigger a denial of service (system crash) via a crafted traffic control     configuration that is set up with tc qdisc and tc class commands. This affects qdisc_graft in     net/sched/sch_api.c. (CVE-2022-47929) (CVE-2023-0179)
