Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> scsi: pm80xx: Set phy-&gt;enable_completion only when we wait for it<br /> <br /> pm8001_phy_control() populates the enable_completion pointer with a stack<br /> address, sends a PHY_LINK_RESET / PHY_HARD_RESET, waits 300 ms, and<br /> returns. The problem arises when a phy control response comes late. After<br /> 300 ms the pm8001_phy_control() function returns and the passed<br /> enable_completion stack address is no longer valid. Late phy control<br /> response invokes complete() on a dangling enable_completion pointer which<br /> leads to a kernel crash.
