"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/erdma: Fix CEQ tasklet use-after-free on removal\n\nEach CEQ interrupt handler only schedules eqc->tasklet. The tasklet calls\nerdma_ceq_completion_handler(), which reads the DMA-coherent EQ ring\nthrough get_next_valid_eqe() and updates eq->dbrec through notify_eq().\n\nerdma_ceqs_uninit() frees each CEQ IRQ and then destroys its EQ.\nfree_irq() prevents another hard IRQ and waits for an in-flight handler,\nbut it does not drain a tasklet that the handler already scheduled. The\ntasklet can therefore access eq->qbuf or eq->dbrec after\nerdma_eq_destroy() frees them.\n\nClearing ceq_cb->ready does not synchronize with a tasklet that already\npassed the check at the start of erdma_ceq_completion_handler().\n\nKill the tasklet after free_irq(), when no handler can schedule it again,\nand before erdma_ceq_uninit_one() releases the EQ buffers."
