Tenable has extracted the preceding description block directly from the SUSE 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 AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1777616064 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: tracing: Fix potential double free in     create_var_ref() In create_var_ref(), init_var_ref() is called to initialize the fields of variable     ref_field, which is allocated in the previous function call to create_hist_field(). Function     init_var_ref() allocates the corresponding fields such as ref_field->system, but frees these fields when     the function encounters an error. The caller later calls destroy_hist_field() to conduct error handling,     which frees the fields and the variable itself. This results in double free of the fields which are     already freed in the previous function. Fix this by storing NULL to the corresponding fields when they are     freed in init_var_ref(). (CVE-2022-49410)

  - In the Linux kernel, the following vulnerability has been resolved: net: mdio: fix undefined behavior in     bit shift for __mdiobus_register Shifting signed 32-bit value by 31 bits is undefined, so changing     significant bit to unsigned. The UBSAN warning calltrace like below: UBSAN: shift-out-of-bounds in     drivers/net/phy/mdio_bus.c:586:27 left shift of 1 by 31 places cannot be represented in type 'int' Call     Trace: <TASK> dump_stack_lvl+0x7d/0xa5 dump_stack+0x15/0x1b ubsan_epilogue+0xe/0x4e

  - In the Linux kernel, the following vulnerability has been resolved: vt: Clear selection before changing     the font When changing the console font with ioctl(KDFONTOP) the new font size can be bigger than the     previous font. A previous selection may thus now be outside of the new screen size and thus trigger out-     of-bounds accesses to graphics memory if the selection is removed in vc_do_resize(). Prevent such out-of-     memory accesses by dropping the selection before the various con_font_set() console handlers are called.
    (CVE-2022-49948)

  - In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: fix double free on     tx path. We see kernel crashes and lockups and KASAN errors related to ax210 firmware crashes. One of the     KASAN dumps pointed at the tx path, and it appears there is indeed a way to double-free an skb. If     iwl_mvm_tx_skb_sta returns non-zero, then the 'skb' sent into the method will be freed. But, in case where     we build TSO skb buffer, the skb may also be freed in error case. So, return 0 in that particular error     case and do cleanup manually.

  - In the Linux kernel, the following vulnerability has been resolved: mmc: rtsx_usb_sdmmc: fix return value     check of mmc_add_host() mmc_add_host() may return error, if we ignore its return value, the memory that     allocated in mmc_alloc_host() will be leaked and it will lead a kernel crash because of deleting not added     device in the remove path. So fix this by checking the return value and calling mmc_free_host() in the     error path, besides, led_classdev_unregister() and pm_runtime_disable() also need be called.

          if (unlikely(READ_ONCE(cpu_buffer->buffer)               != buffer)) { // 3. This check passed due to 'cpu_buffer->buffer'             [...]           //    has not changed here.

    Based on above analysis, we can easily reproduce by following testcase:
      ``` bash       #!/bin/bash

      dmesg -n 7       sysctl -w kernel.panic_on_warn=1       TR=/sys/kernel/tracing       echo 7 > ${TR}/buffer_size_kb       echo sched:sched_switch > ${TR}/set_event       while [ true ]; do               echo 1 > ${TR}/per_cpu/cpu0/snapshot       done &       while [ true ]; do               echo 1 > ${TR}/per_cpu/cpu0/snapshot       done &       while [ true ]; do               echo 1 > ${TR}/per_cpu/cpu0/snapshot       done &       ```

    To fix it, IIUC, we can use smp_call_function_single() to do the swap on     the target cpu where the buffer is located, so that above race would be     avoided.

Tenable has extracted the preceding description block directly from the SUSE 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 Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - tracing: Fix race issue between cpu buffer write and swap Warning happened in rb_end_commit() at code: if     (RB_WARN_ON(cpu_buffer, !local_read(&cpu_buffer->committing))) WARNING: CPU: 0 PID: 139 at     kernel/trace/ring_buffer.c:3142 rb_commit+0x402/0x4a0 Call Trace: ring_buffer_unlock_commit+0x42/0x250     trace_buffer_unlock_commit_regs+0x3b/0x250 trace_event_buffer_commit+0xe5/0x440     trace_event_buffer_reserve+0x11c/0x150 trace_event_raw_event_sched_switch+0x23c/0x2c0

(CVE-2023-53368)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of kernel installed on the remote host is prior to 5.10.196-185.743. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2023-040 advisory.

    An issue was discovered in the USB subsystem in the Linux kernel through 6.4.2. There is an out-of-bounds     and crash in read_descriptors in drivers/usb/core/sysfs.c. (CVE-2023-37453)

    nftables out-of-bounds read in nf_osf_match_one() (CVE-2023-39189)

    A flaw was found in the Netfilter subsystem in the Linux kernel. The xt_u32 module did not validate the     fields in the xt_u32 structure. This flaw allows a local privileged attacker to trigger an out-of-bounds     read by setting the size fields with a value beyond the array boundaries, leading to a crash or     information disclosure. (CVE-2023-39192)

    A flaw was found in the Netfilter subsystem in the Linux kernel. The sctp_mt_check did not validate the     flag_count field. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds     read, leading to a crash or information disclosure. (CVE-2023-39193)

    The upstream commit describes this issue as follows:

    The missing IP_SET_HASH_WITH_NET0 macro in ip_set_hash_netportnet can lead to the use of wrong     `CIDR_POS(c)` for calculating array offsets, which can lead to integer underflow. As a result, it leads to     slab out-of-bound access. (CVE-2023-42753)

    An issue was discovered in drivers/net/ethernet/intel/igb/igb_main.c in the IGB driver in the Linux kernel     before 6.5.3. A buffer size may not be adequate for frames larger than the MTU. (CVE-2023-45871)

    A use-after-free vulnerability in the Linux kernel's net/sched: sch_hfsc (HFSC qdisc traffic control)     component can be exploited to achieve local privilege escalation.

    If a class with a link-sharing curve (i.e. with the HFSC_FSC flag set) has a parent without a link-sharing     curve, then init_vf() will call vttree_insert() on the parent, but vttree_remove() will be skipped in     update_vf(). This leaves a dangling pointer that can cause a use-after-free.

    We recommend upgrading past commit b3d26c5702c7d6c45456326e56d2ccf3f103e60f. (CVE-2023-4623)

    A use-after-free vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited to     achieve local privilege escalation.

    When the plug qdisc is used as a class of the qfq qdisc, sending network packets triggers use-after-free     in qfq_dequeue() due to the incorrect .peek handler of sch_plug and lack of error checking in     agg_dequeue().

    We recommend upgrading past commit 8fc134fee27f2263988ae38920bc03da416b03d8. (CVE-2023-4921)

    A use-after-free vulnerability was found in drivers/nvme/target/tcp.c` in `nvmet_tcp_free_crypto` due to a     logical bug in the NVMe-oF/TCP subsystem in the Linux kernel. This issue may allow a malicious user to     cause a use-after-free and double-free problem, which may permit remote code execution or lead to local     privilege escalation in case that the attacker already has local privileges. (CVE-2023-5178)
