| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the
request threaded irq() function in the gpiolib component of the Linux kernel, which can cause a repeated release of memory, potentially leading to a denial of service. When running a gpio test on the nxp-ls1028 platform with the command gpiomon --num-events=3 --rising-edge gpiochip1 25, a warning trace may occur due to the lineevent state::irq being set before the IRQ register is successful, causing the subsequent invocation of free irq() to trigger a warning call trace. The lineevent free() function is invoked to release the resource after the request threaded irq() function fails.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
