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

ax25: Fix refcount leak caused by setting SO_BINDTODEVICE sockopt

If an AX25 device is bound to a socket by setting the SO_BINDTODEVICE socket option, a refcount leak will occur in ax25_release().

Commit 9fd75b66b8f6 ("ax25: Fix refcount leaks caused by ax25_cb_del()") added decrement of device refcounts in ax25_release(). In order for that to work correctly the refcounts must already be incremented when the device is bound to the socket. An AX25 device can be bound to a socket by either calling ax25_bind() or setting SO_BINDTODEVICE socket option. In both cases the refcounts should be incremented, but in fact it is done only in ax25_bind().

This bug leads to the following issue reported by Syzkaller:

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…
