CVE-2013-3301
HighSummary
Implementacja ftrace w jądrze Linuxa przed wersją 3.8.8 pozwala lokalnym użytkownikom na spowodowanie odmowy usługi (dereferencja wskaźnika NULL i awaria systemu) lub potencjalnie inny nieokreślony wpływ, wykorzystując uprawnienia CAP_SYS_ADMIN do zapisu w plikach set_ftrace_pid lub set_graph_function, a następnie wykonując wywołanie systemowe lseek.
Risk Assessment
Podatność ta może prowadzić do awarii systemu, co wpływa na dostępność usług w organizacji. Dodatkowo, możliwość wykorzystania nieokreślonych skutków może stwarzać dodatkowe zagrożenia dla bezpieczeństwa systemu.
Recommendation
Zaleca się aktualizację jądra Linuxa do wersji 3.8.8 lub nowszej, aby usunąć tę podatność. Należy również ograniczyć dostęp do uprawnień CAP_SYS_ADMIN dla lokalnych użytkowników.

- CVE-2026-6715Critical
IBM Concert 1.0 through 3.0.1.1 allows an attacker to supply crafted input that is incorporated into an operating system command without adequate validation or sanitization. Successful exploitation allows remote attackers to execute arbitrary commands on the underlying operating system with the privileges of the affected service.
Original NVD description (English source)
The ftrace implementation in the Linux kernel before 3.8.8 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by leveraging the CAP_SYS_ADMIN capability for write access to the (1) set_ftrace_pid or (2) set_graph_function file, and then making an lseek system call.
