Description

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+0x2a0/0x4a0 tasklet_action_common+0x274/0x700 tasklet_action+0x28/0x3c _stext+0x188/0x620 run_ksoftirqd+0x34/0x74 smpboot_thread_fn+0x1d8/0x464 kthread+0x178/0x238 ret_from_fork+0x10/0x20 Code: aa0003e8 91000429 f100044a 3940002b (3800150b) ---[ end trace 0fe00bec2b975c99 ]--- Kernel panic - not syncing: Oops: Fatal exception in interrupt.
