fkie_cve-2025-21783

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

gpiolib: Fix crash on error in gpiochip_get_ngpios()

The gpiochip_get_ngpios() uses chip_*() macros to print messages. However these macros rely on gpiodev to be initialised and set, which is not the case when called via bgpio_init(). In such a case the printing messages will crash on NULL pointer dereference. Replace chip_*() macros by the respective dev_*() ones to avoid such crash.

OESA-2025-1285 — kernel security update

Affected: openEuler:24.03-LTS: kernel

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

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

IORING_OP_READ did not correctly consume the provided buffer list when read i/o returned < 0 (except for -EAGAIN and -EIOCBQUEUED return). This can lead to a potential use-after-free when the completion via io_rw_done runs at separate context.(CVE-2023-52926)

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

NFS: Fix potential buffer overflowin nfs_sysfs_link_rpc_client()

name is char[64] where the size of clnt->cl_program->name remains unknown. Invoking strcat() directly will also lead to potential buffer overflow. Change them to strscpy() and strncat() to fix potential issues.(CVE-2024-54456)

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

wifi: mac80211: fix mbss changed flags corruption on 32 bit systems

On 32-bit systems, the size of an unsigned long is 4 bytes, while a u64 is 8 bytes. Therefore, when using or_each_set_bit(bit, &bits, sizeof(changed) * BITS_PER_BYTE), the code is incorrectly searching for a bit in a 32-bit variable that is expected to be 64 bits in size, leading to incorrect bit finding.

Solution: Ensure that the size of the bits variable is correctly adjusted for each architecture.
