https://notcve.org/view.php?id=CVE-2021-47047
28 Feb 2024 — In the Linux kernel, the following vulnerability has been resolved: spi: spi-zynqmp-gqspi: return -ENOMEM if dma_map_single fails The spi controller supports 44-bit address space on AXI in DMA mode, so set dma_addr_t width to 44-bit to avoid using a swiotlb mapping. In addition, if dma_map_single fails, it should return immediately instead of continuing doing the DMA operation which bases on invalid address. This fixes the following crash which occurs in reading a big block from flash: [ 123.633577] zynqmp-... • https://git.kernel.org/stable/c/1c26372e5aa9e53391a1f8fe0dc7cd93a7e5ba9e •

28 Feb 2024 — In the Linux kernel, the following vulnerability has been resolved: sched/fair: Fix shift-out-of-bounds in load_balance() Syzbot reported a handful of occurrences where an sd->nr_balance_failed can grow to much higher values than one would expect. A successful load_balance() resets it to 0; a failed one increments it. Once it gets to sd->cache_nice_tries + 3, this *should* trigger an active balance, which will either set it to sd->cache_nice_tries+1 or reset it to 0.
