Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from a problematic vfstate allocation during PF probing...

The vulnerability of the iavf component in the Linux operating system’s kernel allows a hacker to trigger a service failure.

The vulnerability of the iavf component in the Linux operating system’s kernel is related to errors in resource management within the iavfdisablevf function. Exploiting this vulnerability can allow an attacker to cause a service failure...

The vulnerability of the `filter_frame` function in the `vf_tile.c` component of the FFmpeg multimedia library occurs due to improper memory release before deleting the last reference. This allows a malicious actor to trigger a service failure.

The vulnerability of the filterframe function in the vftile.c component of the FFmpeg multimedia library is related to improper memory release before deleting the last reference. Exploiting this vulnerability could allow a remote attacker to cause a service failure...

CVE-2024-50042

CVE-2022-48949

The CVE-2022-48949 issue affects the Linux kernel igb driver handling VF resets. When a MAC address is not assigned to a VF, the mailbox message portion sent to the VF is not initialized, and the memory backing the message is taken from the stack, potentially leaking information to the VM. The vu...
