EUVD-2026-309554

fkie_cve-2021-47122

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

net: caif: fix memory leak in caif_device_notify

In case of caif_enroll_dev() fail, allocated link_support won't be assigned to the corresponding structure. So simply free allocated pointer in case of error

OESA-2024-1392 — kernel security update

Affected: openEuler:20.03-LTS-SP1: kernel

The Linux Kernel, the operating system core itself. Security Fix(es): In the Linux kernel, the following vulnerability has been resolved: media: dvbdev: Fix memory leak in dvb_media_device_free() dvb_media_device_free() is leaking memory. Free `dvbdev->adapter->conn` before setting it to NULL, as documented in include/media/media-device.h: "The media_entity instance itself must be freed explicitly by the driver if required."(CVE-2020-36777) In the Linux kernel, the following vulnerability has been resolved: i2c: sprd: fix reference leak when pm_runtime_get_sync fails The PM reference count is not expected to be incremented on return in sprd_i2c_master_xfer() and sprd_i2c_remove(). However, pm_runtime_get_sync will increment the PM reference count even failed. Forgetting to putting operation will result in a reference leak here. Replace it with pm_runtime_resume_and_get to keep usage counter balanced.(CVE-2020-36780) In the Linux kernel, the following vulnerability has been resolved: i2c: cadence: fix reference leak when pm_runtime_get_sync fails The PM reference count is not expected to be incremented on return in functions cdns_i2c_master_xfer and cdns_reg_slave. However, pm_runtime_get_sync will increment pm usage counter even failed. Forgetting to putting operation will result in a reference leak here. Replace it with pm_runtime_resume_and_get to keep usage counter balanced.(CVE-2020-36784) In the Linux kernel,…

WID-SEC-W-2024-0652 — Linux Kernel: Mehrere Schwachstellen ermöglichen Denial of Service

Ein lokaler Angreifer kann mehrere Schwachstellen im Linux-Kernel ausnutzen, um einen Denial-of-Service-Zustand herbeizuführen oder einen nicht spezifizierten Angriff durchzuführen.
