Detailsinfo

A vulnerability was found in Linux Kernel up to 6.13.1 and classified as critical. Affected by this issue is the function ath12k_mac_assign_vif_to_vdev. The manipulation with an unknown input leads to a use after free vulnerability. Using CWE to declare the problem leads to CWE-416. Referencing memory after it has been freed can cause a program to crash, use unexpected values, or execute code. Impacted is confidentiality, integrity, and availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix read pointer after free in ath12k_mac_assign_vif_to_vdev() In ath12k_mac_assign_vif_to_vdev(), if arvif is created on a different radio, it gets deleted from that radio through a call to ath12k_mac_unassign_link_vif(). This action frees the arvif pointer. Subsequently, there is a check involving arvif, which will result in a read-after-free scenario. Fix this by moving this check after arvif is again assigned via call to ath12k_mac_assign_link_vif(). Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1
