安全等级: Medium
公告ID: KylinSec-SA-2025-2718
发布日期: 2025年6月11日
关联CVE: CVE-2025-21662 CVE-2024-58058
The Linux Kernel, the operating system core itself.
Security Fix(es):
In the Linux kernel, the following vulnerability has been resolved:
ubifs: skip dumping tnc tree when zroot is null
Clearing slab cache will free all znode in memory and make
c->zroot.znode = NULL, then dumping tnc tree will access
c->zroot.znode which cause null pointer dereference.(CVE-2024-58058)
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Fix variable not being completed when function returns
When cmd_alloc_index(), fails cmd_work_handler() needs
to complete ent->slotted before returning early.
Otherwise the task which issued the command may hang:
mlx5_core 0000:01:00.0: cmd_work_handler:877:(pid 3880418): failed to allocate command entry
