Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - 已修复 Linux 内核中的下列漏洞：ice: fix NULL access of tx->in_use in ice_ll_ts_intr Recent versions of the E810 firmware have support for an extra interrupt to handle report of the low latency Tx timestamps coming from the specialized low latency firmware interface. Instead of polling the registers, software can wait until the low latency interrupt is fired. This logic makes use of the Tx timestamp tracking structure, ice_ptp_tx, as it uses the same ready bitmap to track which Tx timestamps complete. Unfortunately, the ice_ll_ts_intr() function does not check if the tracker is initialized before its first access. This results in NULL dereference or use-after-free bugs similar to the issues fixed in the ice_ptp_ts_irq() function. Fix this by only checking the in_use bitmap (and other fields) if the tracker is marked as initialized. The reset flow will clear the init field under lock before it tears the tracker down, thus preventing any use-after-free or NULL access. (CVE-2025-39854)
