Title
irqchip/mchp-eic: Fix error code in mchp_eic_domain_alloc()
Summary
In the Linux kernel, the following vulnerability has been resolved: irqchip/mchp-eic: Fix error code in mchp_eic_domain_alloc() If irq_domain_translate_twocell() sets "hwirq" to >= MCHP_EIC_NIRQ (2) then it results in an out of bounds access. The code checks for invalid values, but doesn't set the error code. Return -EINVAL in that case, instead of returning success.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

    Related by attack behaviour

    Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
