CVE-2026-89783

CVE-2026-89783 is an out-of-bounds write in the Linux kernel's xfrm6_input_addr() function (net/ipv6/xfrm6_input.c). An off-by-one in the depth check (1 + sp->len == XFRM_MAX_DEPTH instead of >=) allows a write to index 6 of a 6-element xvec[] array when the security path is already at maxi...

CVE-2026-89781

CVE-2026-89781 is an out-of-bounds read in the Linux kernel fs/ntfs3 driver, specifically in read_log_rec_buf() (fs/ntfs3/fslog.c). The function copies a log record using an offset derived from log->record_header_len, which is read verbatim from the on-disk restart area and only validated for ...

CVE-2026-89779

A slab-out-of-bounds read in the Linux kernel's ntfs3 filesystem driver occurs when a crafted NTFS image contains an Extended Attribute (EA) record with a mismatched ef->size and elength. The function ntfs_read_ea() in fs/ntfs3/xattr.c validates only that the record fits in the remaining buffe...

CVE-2026-89780

CVE-2026-89780 is a null-pointer dereference in the Linux kernel's Qualcomm RMNET driver (drivers/net/ethernet/qualcomm/rmnet). The function rmnet_map_deaggregate() allocates sub-frames via alloc_skb() leaving skb->dev as NULL. Because MAP command frames are dispatched to rmnet_map_command() b...

CVE-2026-89778

CVE-2026-89778 is an out-of-bounds page array access in the Linux kernel's zisofs (compressed ISO9660) filesystem. The root cause is in zisofs_uncompress_block()'s empty-block fast path, which returns pcount <

CVE-2026-89776

CVE-2026-89776 affects the Linux kernel VXLAN VNI filter (vxlan: vnifilter). The root cause is that GROUP/GROUP6 address attributes were declared with NLA_BINARY and only a maximum length, allowing validate_nla() to accept payloads shorter than the address. The consumer then performs an unconditi...

CVE-2026-89777

A use-after-free vulnerability in the Linux kernel's VFIO/PCI subsystem (drivers/vfio/pci/vfio_pci_config.c) occurs when vdev->msi_perm is freed via kfree() on an init failure path but not NULLed , leaving a dangling pointer that persists across device open/close cycles. On the next vfio_confi...

CVE-2026-89775

CVE-2026-89775 affects the Linux kernel in the KVM arm64 subsystem. When the S1 MMU is disabled, the page-table walk level is set to −127 (S1_MMU_DISABLED), but pgshift_level_to_ttl() casts it to an unsigned 8-bit value, yielding an invalidation size of 0 during VNCR TLB evaluation. This can leav...

CVE-2026-73464

Arista EOS is affected via its gRPC Network Management Interface (gNMI) component. A specially crafted request from an authenticated client with gNMI access can execute arbitrary code with root privileges on the switch. The root cause is classified as CWE-94 (Code Injection) . Exploitation requir...

CVE-2026-85501

NLnet Labs Unbound up to and including 1.26.0 is vulnerable to a set of DNSSEC algorithmic complexity attacks collectively termed ReTrap . Four distinct vectors are identified: TagTrap (mismatched DNSKEY, RRSIG, and DS records in responses), DelegationTrap (iterative chain-of-trust validation fro...

CVE-2026-82720

NLnet Labs Unbound versions 1.12.0 through 1.26.0 contain a use-after-free vulnerability in the DNS-over-HTTPs (DoH) code path when compiled with --with-libnghttp2. During failure code paths (e.g., RPZ drop query or jostle due to heavy traffic), a dropped DoH stream tears down the entire DoH sess...

CVE-2026-82717

NLnet Labs Unbound versions up to and including 1.26.0 are affected by a heap buffer overflow in CNAME synthesis during upstream response processing. When the resolver enforces a max TTL value in the packet buffer, a compression pointer pointing to the overwritten value invalidates the domain nam...

CVE-2026-81642

NLnet Labs Unbound (up to and including 1.26.0 ) contains a heap buffer overflow in the DNSSEC validator when digesting DNSKEY records. A DNSKEY with an owner compression pointer referencing its own RDATA can overflow the digest buffer, enabling denial of service and possible remote code executio...

CVE-2026-81634

NLnet Labs Unbound up to and including 1.26.0 is affected by a heap buffer overflow in the RRSet canonicalisation routine. The root cause is a missing first owner name in the buffer length check, which can be triggered by a 255-length query name combined with a large TCP response. Since canonical...

CVE-2026-80225

NLnetLabs Unbound versions up to and including 1.26.0 are affected by a degradation of service vulnerability in the TCP/DoT reading procedure . The root cause is the absence of a limit on consecutive reads : a remote, unauthenticated attacker who can sustain a rate of distinct uncached DNS querie...

CVE-2026-78227

NLnet Labs Unbound versions 1.22.0 through 1.26.1 contain a use-after-free vulnerability in the DNS-over-QUIC (DoQ) implementation, triggered only when compiled with '--with-libngtcp2'. The root cause is that ngtcp2's retransmission buffer retains a shallow pointer into a per-stream output buffer...

CVE-2026-77955

NLnet Labs Unbound versions 1.13.2 through 1.26.1 are affected by a timing window in ZONEMD verification for zones configured with zonemd-check: yes located below (but not at) a trust anchor. The root cause is the asynchronous DS/DNSKEY resolution required before the ZONEMD integrity check comple...

CVE-2026-77860

NLnetLabs Unbound versions 1.20.0 through 1.26.0 are affected by a double-decrement flaw in the serve-expired code path that causes the per-client wait-limit counter to be decremented twice. An attacker controlling an authoritative zone with short TTLs can alternate "slow" queries (never answered...

CVE-2026-86338

Ash (Elixir) field_policies were intended to prevent filter-based information disclosure by nilling forbidden field references in filters. The nilling mechanism matched only Ash.Resource.* structs (attributes) but failed to match Ash.Query.Calculation and Ash.Query.Aggregate structs, so filters r...

CVE-2026-88255

CVE-2026-88255 is an improper validation of unsafe equivalence in input in ZenHive mpp (versions 0.2.0 through before 0.16.2). The root cause lies in MPP.Methods.Tempo, where the pre-broadcast dedup reserve (reserve_hash_atomic/2) keys on the caller-supplied raw hex (tx.raw) rather than a canonic...
