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.

[ 23.734156] switchtec switchtec0: MW 0: part 0 addr 0x0000000000000000 size 0x0000000000000000 [ 23.734158] ================================================================================ [ 23.734172] UBSAN: shift-out-of-bounds in drivers/ntb/hw/mscc/ntb_hw_switchtec.c:293:7 [ 23.734418] shift exponent -1 is 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.

Patchwork: https://patchwork.freedesktop.org/patch/624696/(CVE-2024-52559)

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

fs/ntfs3: Mark inode as bad as soon as error detected in mi_enum_attr()

Extended the `mi_enum_attr()` function interface with an additional parameter, `struct ntfs_inode *ni`, to allow marking the inode as bad as soon as an error i…
