CVE-2025-21710

CVE-2025-21710: In the Linux kernel, tcp window advertising under extreme memory squeeze could diverge between the local receive window and the peer, leading to a stall where the peer sends no data. Root cause: the receive window (tp->rcv_wnd) and pending update logic (tp->rcv_wup) could mi...

CVE-2024-57999

The CVE-2024-57999 issue affects PowerPC pseries IOMMU handling in the Linux kernel. The vulnerability arises because the index used when setting the IOMMU bitmap is an int while the address is unsigned long, producing negative bitmap values, and because the DMA offset is treated as page-sh shift...
