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.

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.

It will     result in TX buffer has multiple accessors and the later process interferes with the previous process.

  - 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)).

    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.

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.

    In the Linux kernel, the following vulnerability has been resolved:

    coresight: cti: Fix hang in cti_disable_hw()

    cti_enable_hw() and cti_disable_hw() are called from an atomic context     so shouldn't use runtime PM because it can result in a sleep when     communicating with firmware.

    Since commit 3c6656337852 (Revert firmware: arm_scmi: Add clock     management to the SCMI power domain), this causes a hang on Juno when     running the Perf Coresight tests or running this command:

      perf record -e cs_etm//u -- ls

    This was also missed until the revert commit because pm_runtime_put()     was called with the wrong device until commit 692c9a499b28 (coresight:
    cti: Correct the parameter for pm_runtime_put)

    With lock and scheduler debugging enabled the following is output:
