kernel: idpf: fix read_dev_clk_lock spinlock init in idpf_ptp_init()

A flaw was found in the Linux kernel's Intel Ethernet controller driver idpf. This vulnerability occurs because a critical synchronization mechanism, known as a spinlock, is accessed before it has been properly initialized. An attacker could potentially exploit this timing issue to cause the syst...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fixed an error in the unwind operation of rxecreateqp.

SUSE CVE-2026-43227

In the Linux kernel, the following vulnerability has been resolved: clocksource/drivers/shtmu: Always leave device running after probe The TMU device can be used as both a clocksource and a clockevent provider. The driver tries to be smart and power itself on and off, as well as enabling and...

CVE-2026-43227

A flaw was found in the Linux kernel's clocksource/drivers/shtmu component. This issue arises when the shtmu driver attempts to manage its power and clock states using specific runtime power management functions while holding raw spinlocks. This creates a conflict with other platform drivers that...
