Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
slimbus: messaging: Free transaction ID in delayed interrupt scenario
In case of interrupt delay for any reason, slim_do_transfer() returns timeout error but the transaction ID (TID) is not freed. This results into invalid memory access inside qcom_slim_ngd_rx_msgq_cb() due to invalid TID.
Fix the issue by freeing the TID in slim_do_transfer() before returning timeout error to avoid invalid memory access.
