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

ext4: verify orphan file size is not too big

In principle orphan file can be arbitrarily large. However orphan replay needs to traverse it all and we also pin all its buffers in memory. Thus filesystems with absurdly large orphan files can lead to big amounts of memory consumed. Limit orphan file size to a sane value and also use kvmalloc() for allocating array of block descriptor structures to avoid large order allocations for sane but large orphan files.

OESA-2025-2765 — kernel security update

Affected: openEuler:24.03-LTS: kernel

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

A transient execution vulnerability in some AMD processors may allow an attacker to infer data in the L1D cache, potentially resulting in the leakage of sensitive information across privileged boundaries.(CVE-2024-36357)

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

fs/ntfs3: Prevent integer overflow in hdr_first_de()

The "de_off" and "used" variables come from the disk so they both need to check. The problem is that on 32bit systems if they're both greater than UINT_MAX - 16 then the check does work as intended because of an integer overflow.(CVE-2025-22080)

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

ext4: fix off-by-one error in do_split

Syzkaller detected a use-after-free issue in ext4_insert_dentry that was caused by out-of-bounds access due to incorrect splitting in do_split.

WID-SEC-W-2025-2595 — Linux Kernel: Mehrere Schwachstellen

Ein Angreifer kann mehrere Schwachstellen im Linux-Kernel ausnutzen, um nicht näher spezifizierte Angriffe durchzuführen, die möglicherweise zu einer Denial-of-Service- Bedingung führen oder eine Speicherbeschädigung verursachen können.
