The Rocky Linux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1786352940 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: serial: imx: fix tx statemachine     deadlock When using the serial port as RS485 port, the tx statemachine is used to control the RTS pin to     drive the RS485 transceiver TX_EN pin. When the TTY port is closed in the middle of a transmission (for     instance during userland application crash), imx_uart_shutdown disables the interface and disables the     Transmission Complete interrupt. afer that, imx_uart_stop_tx bails on an incomplete transmission, to be     retriggered by the TC interrupt. This interrupt is disabled and therefore the tx statemachine never     transitions out of SEND. The statemachine is in deadlock now, and the TX_EN remains low, making the     interface useless. imx_uart_stop_tx now checks for incomplete transmission AND whether TC interrupts are     enabled before bailing to be retriggered. This makes sure the state machine handling is reached, and is     properly set to WAIT_AFTER_SEND. (CVE-2023-52456)

  - In the Linux kernel, the following vulnerability has been resolved: kdb: Fix buffer overflow during tab-     complete Currently, when the user attempts symbol completion with the Tab key, kdb will use strncpy() to     insert the completed symbol into the command buffer. Unfortunately it passes the size of the source buffer     rather than the destination to strncpy() with predictably horrible results. Most obviously if the command     buffer is already full but cp, the cursor position, is in the middle of the buffer, then we will write     past the end of the supplied buffer. Fix this by replacing the dubious strncpy() calls with     memmove()/memcpy() calls plus explicit boundary checks to make sure we have enough space before we start     moving characters around. (CVE-2024-39480)

  - In the Linux kernel, the following vulnerability has been resolved: Fix userfaultfd_api to return EINVAL     as expected Currently if we request a feature that is not set in the Kernel config we fail silently and     return all the available features. However, the man page indicates we should return an EINVAL. We need to     fix this issue since we can end up with a Kernel warning should a program request the feature     UFFD_FEATURE_WP_UNPOPULATED on a kernel with the config not set with this feature.

  - In the Linux kernel, the following vulnerability has been resolved: mlxsw: core_linecards: Fix double     memory deallocation in case of invalid INI file In case of invalid INI file mlxsw_linecard_types_init()     deallocates memory but doesn't reset pointer to NULL and returns 0. In case of any error occurred after     mlxsw_linecard_types_init() call, mlxsw_linecards_init() calls mlxsw_linecard_types_fini() which performs     memory deallocation again. Add pointer reset to NULL. Found by Linux Verification Center     (linuxtesting.org) with SVACE. (CVE-2024-42138)

  - In the Linux kernel, the following vulnerability has been resolved: x86/tdx: Fix data leak in mmio_read()     The mmio_read() function makes a TDVMCALL to retrieve MMIO data for an address from the VMM. Sean noticed     that mmio_read() unintentionally exposes the value of an initialized variable (val) on the stack to the     VMM. This variable is only needed as an output value. It did not need to be passed to the VMM in the first     place. Do not send the original value of *val to the VMM. [ dhansen: clarify what 'val' is used for. ]     (CVE-2024-46794)

The AlmaLinux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1786352940 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: serial: imx: fix tx statemachine     deadlock When using the serial port as RS485 port, the tx statemachine is used to control the RTS pin to     drive the RS485 transceiver TX_EN pin. When the TTY port is closed in the middle of a transmission (for     instance during userland application crash), imx_uart_shutdown disables the interface and disables the     Transmission Complete interrupt. afer that, imx_uart_stop_tx bails on an incomplete transmission, to be     retriggered by the TC interrupt. This interrupt is disabled and therefore the tx statemachine never     transitions out of SEND. The statemachine is in deadlock now, and the TX_EN remains low, making the     interface useless. imx_uart_stop_tx now checks for incomplete transmission AND whether TC interrupts are     enabled before bailing to be retriggered. This makes sure the state machine handling is reached, and is     properly set to WAIT_AFTER_SEND. (CVE-2023-52456)

  - In the Linux kernel, the following vulnerability has been resolved: kdb: Fix buffer overflow during tab-     complete Currently, when the user attempts symbol completion with the Tab key, kdb will use strncpy() to     insert the completed symbol into the command buffer. Unfortunately it passes the size of the source buffer     rather than the destination to strncpy() with predictably horrible results. Most obviously if the command     buffer is already full but cp, the cursor position, is in the middle of the buffer, then we will write     past the end of the supplied buffer. Fix this by replacing the dubious strncpy() calls with     memmove()/memcpy() calls plus explicit boundary checks to make sure we have enough space before we start     moving characters around. (CVE-2024-39480)

  - In the Linux kernel, the following vulnerability has been resolved: Fix userfaultfd_api to return EINVAL     as expected Currently if we request a feature that is not set in the Kernel config we fail silently and     return all the available features. However, the man page indicates we should return an EINVAL. We need to     fix this issue since we can end up with a Kernel warning should a program request the feature     UFFD_FEATURE_WP_UNPOPULATED on a kernel with the config not set with this feature.

  - In the Linux kernel, the following vulnerability has been resolved: mlxsw: core_linecards: Fix double     memory deallocation in case of invalid INI file In case of invalid INI file mlxsw_linecard_types_init()     deallocates memory but doesn't reset pointer to NULL and returns 0. In case of any error occurred after     mlxsw_linecard_types_init() call, mlxsw_linecards_init() calls mlxsw_linecard_types_fini() which performs     memory deallocation again. Add pointer reset to NULL. Found by Linux Verification Center     (linuxtesting.org) with SVACE. (CVE-2024-42138)

  - In the Linux kernel, the following vulnerability has been resolved: x86/tdx: Fix data leak in mmio_read()     The mmio_read() function makes a TDVMCALL to retrieve MMIO data for an address from the VMM. Sean noticed     that mmio_read() unintentionally exposes the value of an initialized variable (val) on the stack to the     VMM. This variable is only needed as an output value. It did not need to be passed to the VMM in the first     place. Do not send the original value of *val to the VMM. [ dhansen: clarify what 'val' is used for. ]     (CVE-2024-46794)

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.

  - io_uring: fix incorrect io_kiocb reference in io_link_skb In io_link_skb function, there is a bug where     prev_notif is incorrectly assigned using 'nd' instead of 'prev_nd'. This causes the context validation     check to compare the current notification with itself instead of comparing it with the previous     notification. Fix by using the correct prev_nd parameter when obtaining prev_notif. (CVE-2025-39963)

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