fkie_cve-2025-37994

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

usb: typec: ucsi: displayport: Fix NULL pointer access

This patch ensures that the UCSI driver waits for all pending tasks in the ucsi_displayport_work workqueue to finish executing before proceeding with the partner removal.

GHSA-p49g-r9vw-4fm8

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

usb: typec: ucsi: displayport: Fix NULL pointer access

This patch ensures that the UCSI driver waits for all pending tasks in the ucsi_displayport_work workqueue to finish executing before proceeding with the partner removal.

OESA-2025-2772 — kernel security update

Affected: openEuler:22.03-LTS-SP3: kernel

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

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

media: davinci: vpif: fix use-after-free on driver unbind

The driver allocates and registers two platform device structures during probe, but the devices were never deregistered on driver unbind.

This results in a use-after-free on driver unbind as the device structures were allocated using devres and would be freed by driver core when remove() returns.

Fix this by adding the missing deregistration calls to the remove() callback and failing probe on registration errors.

Note that the platform device structures must be freed using a proper release callback to avoid leaking associated resources like device names.(CVE-2021-47653)

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

mmc: core: use sysfs_emit() instead of sprintf()

sprintf() (still used in the MMC core for the sysfs output) is vulnerable to the buffer overflow. Use the new-fangled sysfs_emit() instead.

Found by Linux Verification Center (linuxtesting.org) with the SVACE static analysis tool.(CVE-2022-49267)

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

Bluetooth: btmtksdio: fix use-after-free at btmtksdio_recv_event

We should not access skb buffer data anymore after hci_recv_frame was called.
