CVE-2026-64235

CVE-2026-64235 refers to a Linux kernel issue where, on x86 with CONFIG_CALL_DEPTH_TRACKING and retbleed protections (e.g., Skylake), relocating percpu references for dynamic ftrace trampolines caused a crash on the first call to a traced function. The crash was due to a mis relocation of the CAL...

PT-2026-64350

Name of the Vulnerable Software and Affected Versions Linux kernel version 7.0.10 Description An issue exists in the x86 ftrace implementation where registering a dynamic ftrace trampoline on retbleed-affected platforms such as Skylake with CONFIG CALL DEPTH TRACKING enabled and retbleed=stuff...

UBUNTU-CVE-2026-56131

libexpat before 2.8.2 lacks handler call depth tracking for calls to XMLResumeParser from within handlers in cases of a policy violation. Thus, a use-after-free can occur similar to the CVE-2026-50219 situation...

CVE-2024-40944

A vulnerability was found in the Linux kernel's x86/kexec component, where the function call to ccplatformhas could lead to a system crash when call depth tracking is active. This issue occurs because the GS segment is reset by loadsegments, setting GSBASE to 0, while call depth tracking relies o...

CVE-2024-40944

CVE-2024-40944 affects the Linux kernel (x86/kexec). The vulnerability is a bug in call depth tracking where calling cc_platform_has() may fault if depth tracking is active because GS_BASE is reset to 0 by load_segments(). The mitigation described in the documentation is to invoke cc_platform_has...
