CVE-2022-49800

CVE-2022-49800 is a Linux kernel issue addressed by multiple advisories. The root cause was a memory-leak in the tracing tests (test_gen_synth_cmd and test_empty_synth_event) where allocated buffers were freed only on failure paths; the fix adds kfree(buf) to ensure no leak. The Nessus/OpenVAS en...

CVE-2022-49793 iio: trigger: sysfs: fix possible memory leak in iio_sysfs_trig_init()

In the Linux kernel, the following vulnerability has been resolved: iio: trigger: sysfs: fix possible memory leak in iiosysfstriginit devsetname allocates memory for name, it need be freed when deviceadd fails, call putdevice to give up the reference that hold in deviceinitialize, so that it can ...

CVE-2022-49793

CVE-2022-49793 is tied to Linux kernel code fixing a memory leak in iio_sysfs_trig_init within iio: trigger: sysfs. The issue arises from dev_set_name() allocating memory for the trigger name and not freeing it if device_add() fails; the fix ensures the allocated memory is released by freeing the...

CVE-2025-23140

CVE-2025-23140 affects the Linux kernel PCI Endpoint Test driver. The issue arose when devm_request_irq() failed in pci_endpoint_test_request_irq(): some IRQs were not released, leaving /proc/irq entries and triggering a WARN in fs/proc/generic.c (remove_proc_entry). The root cause is that pci_en...
