CVE-2025-38067
MediumSummary
W jądrze Linuxa naprawiono podatność, która powodowała błąd segmentacji podczas rejestracji, gdy pole rseq_cs było różne od zera. Pole to powinno być ustawione na 0 przez przestrzeń użytkownika przed rejestracją, jednak nie było to obecnie egzekwowane przez jądro.
Risk Assessment
Brak egzekwowania ustawienia pola rseq_cs na 0 może prowadzić do błędów segmentacji, co może destabilizować system i wpływać na jego dostępność.
Recommendation
Zaleca się aktualizację jądra Linuxa do najnowszej wersji, aby usunąć tę podatność i zapewnić prawidłowe działanie rejestracji rseq.

This could have permitted the attacker to gain full administrative control, including the creation of a new administrative account.
Original NVD description (English source)
In the Linux kernel, the following vulnerability has been resolved: rseq: Fix segfault on registration when rseq_cs is non-zero The rseq_cs field is documented as being set to 0 by user-space prior to registration, however this is not currently enforced by the kernel. This can result in a segfault
