Description
In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix GCC_GCC_PCIE_HOT_RST definition for WCN7850 GCC_GCC_PCIE_HOT_RST is wrongly defined for WCN7850, causing kernel crash on some specific platforms. Since this register is divergent for WCN7850 and QCN9274, move it to register table to allow different definitions. Then correct the register address for WCN7850 to fix this issue. Note IPQ5332 is not affected as it is not PCIe based device. Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3

Can you explain this vulnerability to me?

This vulnerability is due to an incorrect definition of the GCC_GCC_PCIE_HOT_RST register for the WCN7850 device in the Linux kernel's ath12k wifi driver. The wrong definition causes the kernel to crash on some specific platforms. The issue arises because the register differs between WCN7850 and QCN9274 devices. The fix involved moving the register definition to a register table to allow different definitions and correcting the register address for WCN7850.


How can this vulnerability impact me? :

This vulnerability can cause the Linux kernel to crash on certain platforms using the WCN7850 wifi device, potentially leading to system instability or downtime.
