AZL-64896 CVE-2025-38335 affecting package kernel for versions less than 6.6.104.2-1

In the Linux kernel, the following vulnerability has been resolved: Input: gpio-keys - fix a sleep while atomic with PREEMPTRT When enabling PREEMPTRT, the gpiokeysirqtimer callback runs in hard irq context, but the inputevent takes a spinlock, which isn't allowed there as it is converted to a...

AZL-72590 CVE-2025-38335 affecting package kernel for versions less than 5.15.200.1-1

In the Linux kernel, the following vulnerability has been resolved: Input: gpio-keys - fix a sleep while atomic with PREEMPTRT When enabling PREEMPTRT, the gpiokeysirqtimer callback runs in hard irq context, but the inputevent takes a spinlock, which isn't allowed there as it is converted to a...

CVE-2025-38335 Input: gpio-keys - fix a sleep while atomic with PREEMPT_RT

In the Linux kernel, the following vulnerability has been resolved: Input: gpio-keys - fix a sleep while atomic with PREEMPTRT When enabling PREEMPTRT, the gpiokeysirqtimer callback runs in hard irq context, but the inputevent takes a spinlock, which isn't allowed there as it is converted to a...

CVE-2025-38335

CVE-2025-38335 concerns a Linux kernel vulnerability in the gpio_keys driver related to PREEMPT_RT. The description states that when PREEMPT_RT is enabled, gpio_keys_irq_timer() can run in hard IRQ context while input_event() uses a spin_lock, which is incompatible with hard IRQ. This leads to a ...

Use After Free

Overview Affected versions of this package are vulnerable to Use After Free via std::atomicint in reference counting process. An attacker can execute arbitrary code or cause a denial of service by overflowing the reference count and triggering access to memory after it has been freed. Remediation...

DEBIAN-CVE-2025-52886

Poppler is a PDF rendering library. Versions prior to 25.06.0 use std::atomicint for reference counting. Because std::atomicint is only 32 bits, it is possible to overflow the reference count and trigger a use-after-free. Version 25.06.0 patches the issue...

Taylor has race condition in /get-patch that allows purchase token replay

Hi team, I was looking at the recent fix and you limited the exploitability of race conditions but unfortunately it is still possible to exploit the issue since two requests happening at the exact same time will still go through. You should be able to completely fix the race conditions by...

CVE-2025-38029

In the Linux kernel, the following vulnerability has been resolved: kasan: avoid sleepable page allocation from atomic context applytopterange enters the lazy MMU mode and then invokes kasanpopulatevmallocpte callback on each page table walk iteration. However, the callback can go into sleep when...
