n the Linux kernel, the following vulnerability has been resolved: stmmac: intel: Add a missing clk_disable_unprepare() call in intel_eth_pci_remove() Commit 09f012e64e4b ("stmmac: intel: Fix clock handling on error and remove paths") removed this clk_disable_unprepare() This was partly revert by commit ac322f86b56c ("net: stmmac: Fix clock handling on remove path") which removed this clk_disable_unprepare() because: " While unloading the dwmac-intel driver, clk_disable_unprepare() is being called twice in stmmac_dvr_remove() and intel_eth_pci_remove(). This causes kernel panic on the second call. " However later on, commit 5ec55823438e8 ("net: stmmac: add clocks management for gmac driver") has updated stmmac_dvr_remove() which do not call clk_disable_unprepare() anymore. So this call should now be called from intel_eth_pci_remove().

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: stmmac: intel: Añadir una llamada clk_disable_unprepare() faltante en intel_eth_pci_remove(). el commit 09f012e64e4b ("stmmac: intel: Corregir el manejo del reloj en caso de error y eliminar rutas") eliminó esta clk_disable_unprepare(). Esto se revirtió parcialmente mediante el commit ac322f86b56c ("net: stmmac: Corregir el manejo del reloj al eliminar la ruta"), que eliminó esta clk_disable_unprepare() porque: "Al descargar el controlador dwmac-intel, se llama a clk_disable_unprepare() dos veces en stmmac_dvr_remove() e intel_eth_pci_remove(). Esto provoca un pánico del kernel en la segunda llamada". Sin embargo, más tarde, el commit 5ec55823438e8 ("net: stmmac: añadir la gestión de relojes para el controlador gmac") ha actualizado stmmac_dvr_remove() ya no llama a clk_disable_unprepare(). Por lo tanto, esta llamada ahora debe ejecutarse desde intel_eth_pci_remove().
