CVE-2025-21914

Vulnerability overview

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. Call trace: __memcpy_fromio+0x20/0x190 qcom_slim_ngd_rx_msgq_cb+0x130/0x290 [slim_qcom_ngd_ctrl] vchan_complete+0x2a0/0x...
