CVSS: 7.8EPSS: 0%CPEs: 26EXPL: 0CVE-2021-29154 – kernel: Local privilege escalation due to incorrect BPF JIT branch displacement computation
https://notcve.org/view.php?id=CVE-2021-29154
08 Apr 2021 — BPF JIT compilers in the Linux kernel through 5.11.12 have incorrect computation of branch displacements, allowing them to execute arbitrary code within the kernel context. This affects arch/x86/net/bpf_jit_comp.c and arch/x86/net/bpf_jit_comp32.c. Los compiladores BPF JIT en el kernel de Linux hasta la versión 5.11.12 tienen un cálculo incorrecto de los desplazamientos de rama, lo que les permite ejecutar código arbitrario dentro del contexto del kernel.

06 Apr 2021 — The fix for XSA-365 includes initialization of pointers such that subsequent cleanup code wouldn't use uninitialized or stale values. This initialization went too far and may under certain conditions also overwrite pointers which are in need of cleaning up. The lack of cleanup would result in leaking persistent grants. The leak in turn would prevent fully cleaning up after a respective guest has died, leaving around zombie domains. All Linux versions having the fix for XSA-365 applied are vulnerable. • https://lists.debian.org/debian-lts-announce/2021/06/msg00019.html • CWE-665: Improper Initialization •
