DEBIAN-CVE-2023-52984

In the Linux kernel, the following vulnerability has been resolved: net: phy: dp83822: Fix null pointer access on DP83825/DP83826 devices The probe function is only used for the DP83822 PHY, leaving the private data pointer uninitialized for the smaller DP83825/26 models. While all uses of the...

UBUNTU-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...

UBUNTU-CVE-2023-53013

In the Linux kernel, the following vulnerability has been resolved: ptdma: ptcoreexecutecmd should use spinlock The interrupt handler ptcoreirqhandler of the ptdma driver can be called from interrupt context. The code flow in this function can lead down to ptcoreexecutecmd which will attempt to...

CVE-2023-53013 ptdma: pt_core_execute_cmd() should use spinlock

CVE-2023-53013

The CVE-2023-53013 issue in the Linux kernel relates to the ptdma driver: pt_core_irq_handler() could call pt_core_execute_cmd() from interrupt context, where acquiring a mutex is invalid and could cause a kernel panic. The fix replaces the mutex with a spinlock, addressing the interrupt-context ...

CVE-2023-52993 x86/i8259: Mark legacy PIC interrupts with IRQ_LEVEL

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...

CVE-2025-21878

CVE-2025-21878 relates to the Linux kernel i2c npcm driver. The vulnerability arises from not disabling the interrupt enable bit before calling devm_request_irq, leaving an i2c-related status bit that is read-only and triggers repeated interrupts. This behavior can cause a soft lockup and a reboo...
