  3. CVE-2022-49848
In the Linux kernel, the following vulnerability has been resolved: phy: qcom-qmp-combo: fix NULL-deref on runtime resume Commit fc64623637da ("phy: qcom-qmp-combo,usb: add support for separate PCS_USB region") started treating the PCS_USB registers as potentially separate from the PCS registers but used the wrong base when no PCS_USB offset has been provided. Fix the PCS_USB base used at runtime resume to prevent dereferencing a NULL pointer on platforms that do not provide a PCS_USB offset (e.g. SC7180).

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: phy: qcom-qmp-combo: corrección de la desreferencia de NULL al reanudar la ejecución. El commit fc64623637da ("phy: qcom-qmp-combo,usb: añadir compatibilidad con la región PCS_USB independiente") comenzó a tratar los registros PCS_USB como potencialmente independientes de los registros PCS, pero utilizaba la base incorrecta cuando no se proporcionaba un desplazamiento PCS_USB. Se corrigió la base PCS_USB utilizada al reanudar la ejecución para evitar la desreferenciación de un puntero NULL en plataformas que no proporcionan un desplazamiento PCS_USB (p. ej., SC7180).
