Description OSIDB Bzimport 2025-07-25 14:04:59 UTC 
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
