CVE-2022-0882

Illegal access to Kernel log in Fuchsia

A bug exists where an attacker can read the kernel log through exposed Zircon kernel addresses without the required capability ZX_RSRC_KIND_ROOT. It is recommended to upgrade the Fuchsia kernel to 4.1.1 or greater.

CVE-2024-10604

Identifiable Header Values In Fuchsia Leading To Tracking of The User

Vulnerabilities in the algorithms used by Fuchsia to populate network protocol header fields, specifically the TCP ISN, TCP timestamp, TCP and UDP source ports, and IPv4/IPv6 fragment ID allow for these values to be guessed under circumstances

Write access to VMO data through copy-on-write in Fuchsia

An issue exists in Fuchsia where VMO data can be modified through access to copy-on-write snapshots. A local attacker could modify objects in the VMO that they do not have permission to. We recommend upgrading past commit d97c05d2301799ed585620a9c5c739d36e7b5d3d or any of the listed versions.

CVE-2021-22556

Integer Overflow in Fuchsia Kernel

The Security Team discovered an integer overflow bug that allows an attacker with code execution to issue memory cache invalidation operations on pages that they don’t own, allowing them to control kernel memory from userspace. We recommend upgrading to kernel version 4.1 or beyond.

CVE-2021-22566

Incorrect mapping of Executable bits in Fuchsia Kernel

An incorrect setting of UXN bits within mmu_flags_to_s1_pte_attr lead to privileged executable pages being mapped as executable from an unprivileged context. This can be leveraged by an attacker to bypass executability restrictions of kernel-mode pages from user-mode. An incorrect setting of PXN bits within mmu_flags_to_s1_pte_attr lead to unprivileged executable pages being mapped as executable from a privileged context. This can be leveraged by an attacker to bypass executability restrictions of user-mode pages from kernel-mode. Typically this allows a potential attacker to circumvent a mitigation, making exploitation of potential kernel-mode vulnerabilities easier. We recommend updating kernel beyond commit 7d731b4e9599088ac3073956933559da7bca6a00 and rebuilding.
