CVE-2026-43331
Summary of details (CVE-2026-43331): In the Linux kernel, a KCOV instrumentation issue in the x86/kexec path is resolved by disabling KCOV for the affected areas. The root cause is that load_segments() changes segment registers and invalidates the GS base KCOV relies on for per-CPU data, causing ...

When CONFIGKCOV is enabled, any subsequent instrumented C...
CVE-2026-43289
CVE-2026-43289 relates to the Linux kernel kexec flow. The patch fixes kexec_load_purgatory() so image->start is derived from the purgatory_start symbol when present, rather than blindly locating e_entry within an SHF_EXECINSTR section. This prevents the entrypoint check from matching multiple...
