An update of the linux package has been released.

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1779987841 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: net: hns3: do not allow call     hns3_nic_net_open repeatedly hns3_nic_net_open() is not allowed to called repeatly, but there is no     checking for this. When doing device reset and setup tc concurrently, there is a small oppotunity to call     hns3_nic_net_open repeatedly, and cause kernel bug by calling napi_enable twice. The calltrace information     is like below: [ 3078.222780] ------------[ cut here ]------------ [ 3078.230255] kernel BUG at     net/core/dev.c:6991!

    (CVE-2021-47400)

  - In the Linux kernel, the following vulnerability has been resolved: can: isotp: isotp_sendmsg(): add     result check for wait_event_interruptible() Using wait_event_interruptible() to wait for complete     transmission, but do not check the result of wait_event_interruptible() which can be interrupted. It will     result in TX buffer has multiple accessors and the later process interferes with the previous process.
    Following is one of the problems reported by syzbot.

  - In the Linux kernel, the following vulnerability has been resolved: serial: core: fix transmit-buffer     reset and memleak Commit 761ed4a94582 (tty: serial_core: convert uart_close to use tty_port_close)     converted serial core to use tty_port_close() but failed to notice that the transmit buffer still needs to     be freed on final close. Not freeing the transmit buffer means that the buffer is no longer cleared on     next open so that any ioctl() waiting for the buffer to drain might wait indefinitely (e.g. on termios     changes) or that stale data can end up being transmitted in case tx is restarted. Furthermore, the buffer     of any port that has been opened would leak on driver unbind. Note that the port lock is held when     clearing the buffer pointer due to the ldisc race worked around by commit a5ba1d95e46e (uart: fix race     between uart_put_char() and uart_shutdown()). Also note that the tty-port shutdown() callback is not     called for console ports so it is not strictly necessary to free the buffer page after releasing the lock     (cf. d72402145ace (tty/serial: do not free trasnmit buffer page under port lock)). (CVE-2021-47527)

  - In the Linux kernel, the following vulnerability has been resolved: mm/gup: fix gup_pud_range() for dax     For dax pud, pud_huge() returns true on x86. So the function works as long as hugetlb is configured.
    However, dax doesn't depend on hugetlb. Commit 414fd080d125 (mm/gup: fix gup_pmd_range() for dax) fixed     devmap-backed huge PMDs, but missed devmap-backed huge PUDs. Fix this as well. This fixes the below kernel     panic: general protection fault, probably for non-canonical address 0x69e7c000cc478: 0000 [#1] SMP < snip     > Call Trace: <TASK> get_user_pages_fast+0x1f/0x40 iov_iter_get_pages+0xc6/0x3b0 ?     mempool_alloc+0x5d/0x170 bio_iov_iter_get_pages+0x82/0x4e0 ? bvec_alloc+0x91/0xc0 ?     bio_alloc_bioset+0x19a/0x2a0 blkdev_direct_IO+0x282/0x480 ? __io_complete_rw_common+0xc0/0xc0 ?     filemap_range_has_page+0x82/0xc0 generic_file_direct_write+0x9d/0x1a0 ? inode_update_time+0x24/0x30

  - In the Linux kernel, the following vulnerability has been resolved: lz4: fix LZ4_decompress_safe_partial     read out of bound When partialDecoding, it is EOF if we've either filled the output buffer or can't     proceed with reading an offset for following match. In some extreme corner cases when compressed data is     suitably corrupted, UAF will occur. As reported by KASAN [1], LZ4_decompress_safe_partial may lead to read     out of bound problem during decoding. lz4 upstream has fixed it [2] and this issue has been disscussed     here [3] before. current decompression routine was ported from lz4 v1.8.3, bumping lib/lz4 to v1.9.+ is     certainly a huge work to be done later, so, we'd better fix it first.

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

The Rocky Linux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1780562693 advisory.

  - An issue was discovered in the Linux kernel before 5.16.12. drivers/net/usb/sr9700.c allows attackers to     obtain sensitive information from heap memory via crafted frame lengths from a device. (CVE-2022-26966)

  - In the Linux kernel, the following vulnerability has been resolved: kprobes: don't call disarm_kprobe()     for disabled kprobes The assumption in __disable_kprobe() is wrong, and it could try to disarm an already     disarmed kprobe and fire the WARN_ONCE() below. [0] We can easily reproduce this issue. 1. Write 0 to     /sys/kernel/debug/kprobes/enabled. # echo 0 > /sys/kernel/debug/kprobes/enabled 2. Run execsnoop.

    Then, __unregister_trace_kprobe() initialises tk->rp.kp.list and creates an infinite loop like this.

  - In the Linux kernel, the following vulnerability has been resolved: tracing/hist: Fix out-of-bound write     on 'action_data.var_ref_idx' When generate a synthetic event with many params and then create a trace     action for it [1], kernel panic happened [2]. It is because that in trace_action_create() 'data->n_params'     is up to SYNTH_FIELDS_MAX (current value is 64), and array 'data->var_ref_idx' keeps indices into array     'hist_data->var_refs' for each synthetic event param, but the length of 'data->var_ref_idx' is     TRACING_MAP_VARS_MAX (current value is 16), so out-of-bound write happened when 'data->n_params' more than     16. In this case, 'data->match_data.event' is overwritten and eventually cause the panic. To solve the     issue, adjust the length of 'data->var_ref_idx' to be SYNTH_FIELDS_MAX and add sanity checks to avoid out-     of-bound write.

  - In the Linux kernel, the following vulnerability has been resolved: net: can: j1939: enhanced error     handling for tightly received RTS messages in xtp_rx_rts_session_new This patch enhances error handling in     scenarios with RTS (Request to Send) messages arriving closely. It replaces the less informative     WARN_ON_ONCE backtraces with a new error handling method. This provides clearer error messages and allows     for the early termination of problematic sessions. Previously, sessions were only released at the end of     j1939_xtp_rx_rts(). Potentially this could be reproduced with something like: testj1939 -r vcan0:0x80 &     while true; do # send first RTS cansend vcan0 18EC8090#1014000303002301; # send second RTS cansend vcan0     18EC8090#1014000303002301; # send abort cansend vcan0 18EC8090#ff00000000002301; done (CVE-2023-52887)

  - In the Linux kernel, the following vulnerability has been resolved: net: fec: remove .ndo_poll_controller     to avoid deadlocks There is a deadlock issue found in sungem driver, please refer to the commit     ac0a230f719b (eth: sungem: remove .ndo_poll_controller to avoid deadlocks). The root cause of the issue     is that netpoll is in atomic context and disable_irq() is called by .ndo_poll_controller interface of     sungem driver, however, disable_irq() might sleep. After analyzing the implementation of     fec_poll_controller(), the fec driver should have the same issue. Due to the fec driver uses NAPI for TX     completions, the .ndo_poll_controller is unnecessary to be implemented in the fec driver, so     fec_poll_controller() can be safely removed. (CVE-2024-38553)
