CVE-2024-35879

CVE-2024-35879 affects the Linux kernel’s dynamic handling of device trees: synchronization of of_changeset_destroy() with devlink removals in the OF stack. The issue arises during a two-step sequence (1) of_platform_depopulate() destroying devices and removing devlinks, then (2) of_overlay_remov...

CVE-2021-47239

CVE-2021-47239 : In Linux kernel net/usb, theSmsc75xx driver has a use-after-free in smsc75xx_bind caused by not cleaning up a scheduled work in smsc75xx_reset→smsc75xx_set_multicast. The patch 46a8b29c6306 adds cancel_work_sync and NULLs the dangling pointer (dev->data[0]) to prevent use-afte...

CVE-2025-39703

CVE-2025-39703 affects the Linux kernel net/hsr path. When an HSR frame arrives with insufficient space for the HSR tag, the skb cannot accommodate headers, leading to a panicked skb_push() in br_dev_queue_push_xmit() and a kernel crash. The issue stems from corrupted HSR frames being processed b...
