Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw related to interrupt request (IRQ) handling on the arm64 architecture. Specifically, the
filter irq stacks() function, intended to filter IRQ-related entries from the call stack, does not function correctly when the CONFIG FUNCTION GRAPH TRACER option is disabled. This can lead to unintended deep call stack entries, particularly in situations where Kernel Address Sanitizer (KASAN) is enabled. This issue arises because the gic handle irq entry point, which is the entry point for arm64 IRQs, is not included between the irqentry text start and irqentry text end symbols when the function graph tracer is not active. This can result in stack depot capacity issues and potential crashes.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
