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

ntb_hw_switchtec: Fix shift-out-of-bounds in switchtec_ntb_mw_set_trans

There is a kernel API ntb_mw_clear_trans() would pass 0 to both addr and size. This would make xlate_pos negative.

OESA-2025-1446 — kernel security update

Affected: openEuler:24.03-LTS-SP1: kernel

The Linux Kernel, the operating system core itself. Security Fix(es):

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

ntb_hw_switchtec: Fix shift-out-of-bounds in switchtec_ntb_mw_set_trans

There is a kernel API ntb_mw_clear_trans() would pass 0 to both addr and size. This would make xlate_pos negative.

Ensuring xlate_pos is a positive or zero before BIT.(CVE-2023-53034)

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

drm/msm/gem: prevent integer overflow in msm_ioctl_gem_submit()

The "submit->cmd[i].size" and "submit->cmd[i].offset" variables are u32 values that come from the user via the submit_lookup_cmds() function. This addition could lead to an integer wrapping bug so use size_add() to prevent that.

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