Important: kernel

Issue Overview: In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables: double hook unregistration in netns path CVE-2022-49558 A race condition leading to a use-after-free issue was found in the QXL driver in the Linux kernel. CVE-2023-39198 A use-after-free...

The vulnerability of the nft_set_commit_update() function in the net/netfilter/nf_tables_api.c module of the netfilter component of the Linux kernel allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information, thereby enhancing their privileges.

The vulnerability of the nftsetcommitupdate function in the net/netfilter/nftablesapi.c module of the netfilter component of the Linux kernel operating system is related to the repeated use of previously freed memory. Exploiting this vulnerability could allow a privileged attacker to compromise t...

DEBIAN-CVE-2023-46835

The current setup of the quarantine page tables assumes that the quarantine domain domio has been initialized with an address width of DEFAULTDOMAINADDRESSWIDTH 48 and hence 4 page table levels. However domio being a PV domain gets the AMD-Vi IOMMU page tables levels based on the maximum hot...

CVE-2023-34322

For migration as well as to work around kernels unaware of L1TF see XSA-273, PV guests may be run in shadow paging mode. Since Xen itself needs to be mapped when PV guests run, Xen and shadowed PV guests run directly the respective shadow page tables. For 64-bit PV guests this means running on th...

CVE-2023-46835

CVE-2023-46835 affects Xen on x86/AMD with a mismatch in IOMMU quarantine page table levels. The quarantine domain (dom_io) expects 4 page table levels (DEFAULT_DOMAIN_ADDRESS_WIDTH 48), but on PV domains the AMD-Vi IOMMU page tables can be configured with only 3 levels for RAM up to 512 GB. Cons...

CVE-2023-34322

CVE-2023-34322 concerns Xen hypervisor shadow paging handling during memory pressure. In PV (paravirtualized) guests, Xen and shadowed PV guests map the guest root page table in shadow mode, so 64-bit PV guests operate on the shadow root page table. Under memory scarcity, shadows of page tables m...
