Linux Distros Unpatched Vulnerability : CVE-2026-80853

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - In the Linux kernel, the following vulnerability has been resolved: KVM: SEV: Allocate full pages for DE,ENCRYPT ops on SNP-enabled hosts When de,encrypting...

CVE-2026-80853

CVE-2026-80853 affects the Linux kernel KVM subsystem on SNP-enabled hosts . When KVM performs {de,en}crypt operations for an SEV or SEV-ES guest, it used a sub-page allocation for its temporary buffer. On SNP platforms, pages written by firmware are temporarily transferred to Firmware ownership ...

In the Linux kernel, the following vulnerability has been resolved: KVM: SEV: Allocate full pages for DE,ENCRYPT ops on SNP-enabled hosts When de,encrypting memory of an SEV or SEV-ES guest on an SNP-enabled host via a temporary buffer, allocate a full 4KiB page for the buffer to ensure the page...

CVE-2026-53199 hv_netvsc: use kmap_local_page in netvsc_copy_to_send_buf

In the Linux kernel, the following vulnerability has been resolved: hvnetvsc: use kmaplocalpage in netvsccopytosendbuf netvsccopytosendbuf copies page buffer entries into the VMBus send buffer using phystovirt on the entry PFN. Entries for the RNDIS header and the skb linear data come from...

CVE-2026-53199

CVE-2026-53199 pertains to the Linux kernel hv_netvsc path, where netvsc_copy_to_send_buf previously used phys_to_virt() on page buffer PFNs and could fault when fragments referenced high mem/user pages on 32-bit x86 with HIGHMEM. The fix maps pages with kmap_local_page() and reconstructs native ...

kernel: NFSD: Protect against send buffer overflow in NFSv2 READ

In the Linux kernel, the following vulnerability has been resolved: NFSD: Protect against send buffer overflow in NFSv2 READ Since before the git era, NFSD has conserved the number of pages held by each nfsd thread by combining the RPC receive and send buffers into a single array of pages. This...
