SUSE CVE-2023-52993

In the Linux kernel, the following vulnerability has been resolved: x86/i8259: Mark legacy PIC interrupts with IRQLEVEL Baoquan reported that after triggering a crash the subsequent crash-kernel fails to boot about half of the time. It triggers a NULL pointer dereference in the periodic tick code...

CVE-2023-52993

CVE-2023-52993 affects the Linux kernel’s x86/i8259 legacy interrupt handling. The root cause is that IRQ_LEVEL was not set for legacy PIC interrupts, allowing a spurious APIC interrupt on IRQ0 to trigger a software resend of the legacy timer interrupt, which in the softirq/tasklet context can yi...
