CVE-2026-43462

CVE-2026-43462 affects the Linux kernel spacemit network driver. An error in the function emac_tx_mem_map() could leak DMA mappings on a mapping failure. This resource mismanagement may lead to a denial of service, impacting system availability. The published fix frees the leaked DMA mappings usi...

CVE-2026-43461

CVE-2026-43461 affects the Linux kernel’s spi: amlogic: spifc-a4 driver, specifically aml_sfc_dma_buffer_setup(). The patch fixes three DMA mapping error paths: (1) removing an unnecessary goto when sfc->daddr mapping fails, (2) preventing a double-unmap when info DMA mapping fails by avoiding...

CVE-2026-43445

In the Linux kernel, the following vulnerability has been resolved: e1000/e1000e: Fix leak in DMA error cleanup If an error is encountered while mapping TX buffers, the driver should unmap any buffers already mapped for that skb. Because count is incremented after a successful mapping, it will...

CVE-2026-43445

CVE-2026-43445 is a Linux kernel vulnerability in the e1000/e1000e drivers (and potentially igbvf) where a DMA mapping error cleanup leak could occur. The root cause was an off-by-one condition in the dma_error path: count was decremented before the loop, so if any TX buffer mappings succeeded be...

CVE-2026-43434

In the Linux kernel, the following vulnerability has been resolved: rustbinder: check ownership before using vma When installing missing pages or zapping them, Rust Binder will look up the vma in the mm by address, and then call vminsertpage or zappagerangesingle. However, if the vma is closed an...

In the Linux kernel, the following vulnerability has been resolved: rustbinder: check ownership before using vma When installing missing pages or zapping them, Rust Binder will look up the vma in the mm by address, and then call vminsertpage or zappagerangesingle. However, if the vma is closed an...

CVE-2026-43433

In the Linux kernel, the following vulnerability has been resolved: rustbinder: avoid reading the written value in offsets array When sending a transaction, its offsets array is first copied into the target proc's vma, and then the values are read back from there. This is normally fine because th...
