CVE-2024-43876

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A link problem in the Linux kernel has been resolved by demoting WARN() to dev warn ratelimited() in rcar pcie wakeup(). This issue occurs when an ASMedia ASM1062 PCIe SATA controller, which does not support ASPM, enters D3hot state and the link enters L1 state during suspend or platform pm test. If the SATA controller wakes up before rcar pcie wakeup() is called and returns to D0, the link returns to L0 before the controller driver starts its transition to L1 link state. The controller driver then attempts to perform the transition to L1 link state unconditionally, resulting in a PMSR L1FAEG poll timeout. However, the link still works as it is already back in L0 state. This change reduces the warning verbosity, and in case the link is really broken, the rcar pcie config access() would fail.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
