CVE-2025-21914: slimbus: messaging: Free transaction ID in delayed interrupt scenario

Published Apr 1, 2025
·
Updated

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, slimdotransfer() returns timeout error but the transaction ID (TID) is not freed. This results into invalid memory access inside qcomslimngdrxmsgqcb() due to invalid TID.

Fix the issue by freeing the TID in slimdotransfer() before returning timeout error to avoid invalid memory access.
