CVE-2024-47666 Information

Description

In the Linux kernel the following vulnerability has been resolved:

scsi: pm80xx: Set phy->enable_completion only when we wait for it

pm8001_phy_control() populates the enable_completion pointer with a stack address sends a PHY_LINK_RESET / PHY_HARD_RESET waits 300 ms and returns. The problem arises when a phy control response comes late. After 300 ms the pm8001_phy_control() function returns and the passed enable_completion stack address is no longer valid. Late phy control response invokes complete() on a dangling enable_completion pointer which leads to a kernel crash.
