A vulnerability was found in the Linux kernel's EBPF verifier when handling internal data structures. Internal memory locations could be returned to userspace. A local attacker with the permissions to insert eBPF code to the kernel can use this to leak internal kernel memory details defeating some of the exploit mitigations in place for the kernel. Se encontró una vulnerabilidad en el verificador EBPF del kernel de Linux cuando son manejadas estructuras de datos internas. Las ubicaciones de memoria interna podían ser devueltas al espacio de usuario. • https://access.redhat.com/security/cve/CVE-2021-4159 https://bugzilla.redhat.com/show_bug.cgi?id=2036024 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=294f2fc6da27620a506e6c050241655459ccd6bd https://lists.debian.org/debian-lts-announce/2022/10/msg00000.html https://security-tracker.debian.org/tracker/CVE-2021-4159 • CWE-202: Exposure of Sensitive Information Through Data Queries •
