Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

The remote AlmaLinux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2023:2458 advisory.

  - Some AMD CPUs may transiently execute beyond unconditional direct branches, which may potentially result     in data leakage. (CVE-2021-26341)

  - When sending malicous data to kernel by ioctl cmd FBIOPUT_VSCREENINFO,kernel will write memory out of     bounds. (CVE-2021-33655)

  - An out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a     user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage     of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read     unauthorized random data from memory. (CVE-2022-1462)

  - With shadow paging enabled, the INVPCID instruction results in a call to kvm_mmu_invpcid_gva. If INVPCID     is executed with CR0.PG=0, the invlpg callback is not set and the result is a NULL pointer dereference.
    (CVE-2022-1789)

  - A use-after-free flaw was found in the Linux kernel's pipes functionality in how a user performs     manipulations with the pipe post_one_notification() after free_pipe_info() that is already called. This     flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-1882)

  - 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)

  - A regression exists in the Linux Kernel within KVM: nVMX that allowed for speculative execution attacks.
    L2 can carry out Spectre v2 attacks on L1 due to L1 thinking it doesn't need retpolines or IBPB after     running L2 due to KVM (L0) advertising eIBRS support to L1. An attacker at L2 with code execution can     execute code on an indirect branch on the host machine. We recommend upgrading to Kernel 6.2 or past     commit 2e7eab81425a (CVE-2022-2196)

  - An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and     incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted     IRC with nf_conntrack_irc configured. (CVE-2022-2663)

  - usb_8dev_start_xmit in drivers/net/can/usb/usb_8dev.c in the Linux kernel through 5.17.1 has a double     free. (CVE-2022-28388)

  - A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem)     when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to     potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read     and copying it into a socket. (CVE-2022-3028)

  - network backend may cause Linux netfront to use freed SKBs While adding logic to support XDP (eXpress Data     Path), a code label was moved in a way allowing for SKBs having references (pointers) retained for further     processing to nevertheless be freed. (CVE-2022-33743)

  - A double-free memory flaw was found in the Linux kernel. The Intel GVT-g graphics driver triggers VGA card     system resource overload, causing a fail in the intel_gvt_dma_map_guest_page function. This issue could     allow a local user to crash the system. (CVE-2022-3707)

  - An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race     condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale     TLB entries. This only occurs in situations with VM_PFNMAP VMAs. (CVE-2022-39188)

  - An issue was discovered the x86 KVM subsystem in the Linux kernel before 5.18.17. Unprivileged guest users     can compromise the guest kernel because TLB flush operations are mishandled in certain KVM_VCPU_PREEMPTED     situations. (CVE-2022-39189)

  - A NULL pointer dereference issue was discovered in the Linux kernel in the MPTCP protocol when traversing     the subflow list at disconnect time. A local user could use this flaw to potentially crash the system     causing a denial of service. (CVE-2022-4128)

  - 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)

  - An issue was discovered in the Linux kernel before 5.19.16. Attackers able to inject WLAN frames could     cause a buffer overflow in the ieee80211_bss_info_update function in net/mac80211/scan.c. (CVE-2022-41674)

  - 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)

  - Various refcounting bugs in the multi-BSS handling in the mac80211 stack in the Linux kernel 5.1 through     5.19.x before 5.19.16 could be used by local attackers (able to inject WLAN frames) to trigger use-after-     free conditions to potentially execute code. (CVE-2022-42720)

  - A list management bug in BSS handling in the mac80211 stack in the Linux kernel 5.1 through 5.19.x before     5.19.16 could be used by local attackers (able to inject WLAN frames) to corrupt a linked list and, in     turn, potentially execute code. (CVE-2022-42721)

  - In the Linux kernel 5.8 through 5.19.x before 5.19.16, local attackers able to inject WLAN frames into the     mac80211 stack could cause a NULL pointer dereference denial-of-service attack against the beacon     protection of P2P devices. (CVE-2022-42722)

  - There are use-after-free vulnerabilities in the Linux kernel's net/bluetooth/l2cap_core.c's l2cap_connect     and l2cap_le_connect_req functions which may allow code execution and leaking kernel memory (respectively)     remotely via Bluetooth. A remote attacker could execute code leaking kernel memory via Bluetooth if within     proximity of the victim. We recommend upgrading past commit https://www.google.com/url     https://github.com/torvalds/linux/commit/711f8c3fb3db61897080468586b970c87c61d9e4     https://www.google.com/url (CVE-2022-42896)

  - drivers/usb/mon/mon_bin.c in usbmon in the Linux kernel before 5.19.15 and 6.x before 6.0.1 allows a user-     space client to corrupt the monitor's internal memory. (CVE-2022-43750)

  - 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 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)

  - 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)

  - A use-after-free flaw was found in qdisc_graft in net/sched/sch_api.c in the Linux Kernel due to a race     problem. This flaw leads to a denial of service issue. If patch ebda44da44f6 (net: sched: fix race     condition in qdisc_graft()) not applied yet, then kernel could be affected. (CVE-2023-0590)

  - A data race flaw was found in the Linux kernel, between where con is allocated and con->sock is set. This     issue leads to a NULL pointer dereference when accessing con->sock->sk in net/tipc/topsrv.c in the tipc     protocol in the Linux kernel. (CVE-2023-1382)

  - AMD recommends using a software mitigation for this issue, which the kernel is enabling by default. The     Linux kernel will use the generic retpoline software mitigation, instead of the specialized AMD one, on     AMD instances (*5a*). This is done by default, and no administrator action is needed. (CVE-2021-26341)     (CVE-2022-21505)

  - 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 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)

  - 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)

  - A data race flaw was found in the Linux kernel, between where con is allocated and con->sock is set. This     issue leads to a NULL pointer dereference when accessing con->sock->sk in net/tipc/topsrv.c in the tipc     protocol in the Linux kernel. (CVE-2023-1382)

  - AMD recommends using a software mitigation for this issue, which the kernel is enabling by default. The     Linux kernel will use the generic retpoline software mitigation, instead of the specialized AMD one, on     AMD instances (*5a*). This is done by default, and no administrator action is needed. (CVE-2021-26341)     (CVE-2022-21505)
