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

wifi: brcmfmac: ensure CLM version is null-terminated to prevent stack-out-of-bounds

Fix a stack-out-of-bounds read in brcmfmac that occurs when 'buf' that is not null-terminated is passed as an argument of strreplace() in brcmf_c_preinit_dcmds(). This buffer is filled with a CLM version string by memcpy() in brcmf_fil_iovar_data_get(). Ensure buf is null-terminated.

Found by a modified version of syzkaller.

OESA-2025-2659 — kernel security update

2026-09-29T19:56:56.682658+00:00

Affected: openEuler:20.03-LTS-SP4: kernel

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

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

misc: tifm: fix possible memory leak in tifm_7xx1_switch_media()

If device_register() returns error in tifm_7xx1_switch_media(), name of kobject which is allocated in dev_set_name() called in device_add() is leaked.

Never directly free @dev after calling device_register(), even if it returned an error! Always use put_device() to give up the reference initialized.(CVE-2022-50349)

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

net: hns: fix possible memory leak in hnae_ae_register()

Inject fault while probing module, if device_register() fails, but the refcount of kobject is not decreased to 0, the name allocated in dev_set_name() is leaked. Fix this by calling put_device(), so that name can be freed in callback function kobject_cleanup().
