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

jffs2: fix memory leak in jffs2_do_fill_super

If jffs2_iget() or d_make_root() in jffs2_do_fill_super() returns an error, we can observe the following kmemleak report:

OESA-2025-1336 — kernel security update

2026-10-05T17:54:07.031971+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:

drm/plane: Move range check for format_count earlier

While the check for format_count > 64 in __drm_universal_plane_init() shouldn't be hit (it's a WARN_ON), in its current position it will then leak the plane->format_types array and fail to call drm_mode_object_unregister() leaking the modeset identifier. Move it to the start of the function to avoid allocating those resources in the first place.(CVE-2021-47659)

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

scsi: target: tcmu: Fix possible page UAF

tcmu_try_get_data_page() looks up pages under cmdr_lock, but it does not take refcount properly and just returns page pointer. When tcmu_try_get_data_page() returns, the returned page may have been freed by tcmu_blocks_release().

We need to get_page() under cmdr_lock to avoid concurrent tcmu_blocks_release().(CVE-2022-49053)

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

ASoC: atmel: Add missing of_node_put() in at91sam9g20ek_audio_probe

This node pointer is returned by of_parse_phandle() with refcount incremented in this function. Calling of_node_put() to avoid the refcount leak.(CVE-2022-49243)

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