Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description In the drm/panthor component, the system fails to verify if vm bind mappings of user-mode exposed Buffer Objects BOs intersect with the address space carve-out reserved for mapping kerne...

CVE-2026-19941

A flaw was found in BIND 9. A remote attacker could exploit this by providing an inapplicable NSEC Next Secure record to a named resolver. This could allow the attacker to mask the existence of a victim's wildcard DNS Domain Name System record, potentially leading to a misrepresentation of DNS...

CVE-2026-77119

A flaw was found in BIND 9. A remote attacker could exploit a vulnerability where a validly signed NSEC3 record from an unrelated DNS zone might be accepted as proof of insecurity. This could downgrade a secure delegation, allowing forged unsigned DNS answers to be accepted by the resolver,...

CVE-2026-19662

A flaw was found in BIND 9. A remote attacker can cause a named resolver to stop functioning Denial of Service by inducing the victim resolver to send multiple queries for a DNSSEC-signed zone. If the attacker's authoritative server responds with a specific sequence of crafted answers that arrive...

CLSA-2026-1789580964 389-ds-base: Fix of 4 CVEs

CVE-2026-18922: reset the SASL auxprop context after a failed one-shot bind so a stale canonuser identity cannot be inherited by a later successful bind - CVE-2026-18355: validate the minimum SASL packet length in sasliostartpacket to prevent an unsigned underflow in saslioreadpacket -...

bind9: bind: BIND 9: Denial of Service via 16-bit length truncation in DNS negative cache handling

A flaw was found in bind9's named component. A remote attacker, by sending a specially crafted DNS negative answer of exactly 65536 bytes from an authoritative server, can cause a 16-bit length truncation. This results in a zero-byte negative cache entry. When named attempts to read this invalid...

bind: BIND: Unauthorized zone content updates via unauthenticated IXFR deltas

A flaw was found in bind. A remote attacker without a valid TSIG Transaction Signature can send unauthorized zone contents to a secondary server during a multi-message TCP IXFR Incremental Zone Transfer. The named process may apply this unauthenticated data before the TSIG signature is verified. ...

bind9: bind: BIND 9: Denial of Service via crafted DNSSEC responses

A flaw was found in BIND 9. A remote attacker can cause a named resolver to stop functioning Denial of Service by inducing the victim resolver to send multiple queries for a DNSSEC-signed zone. If the attacker's authoritative server responds with a specific sequence of crafted answers that arrive...

bind: BIND: Denial of Service via TKEY query with specific configuration

A flaw was found in BIND. A remote attacker can exploit this vulnerability by sending a specially crafted TKEY query to a BIND server configured without a global 'options' block in its 'named.conf' file. This can lead to an assertion failure, causing the BIND program to unexpectedly terminate. Th...

bind9: bind: BIND 9: DNSSEC bypass via NSEC3 insecure-referral proof

A flaw was found in BIND 9. A remote attacker could exploit a vulnerability where a validly signed NSEC3 record from an unrelated DNS zone might be accepted as proof of insecurity. This could downgrade a secure delegation, allowing forged unsigned DNS answers to be accepted by the resolver,...

bind: BIND: Remote Denial of Service via crafted DNS-over-HTTPS request

A flaw was found in BIND, a widely used Domain Name System DNS software. A remote attacker can exploit this vulnerability by sending a specially crafted DNS-over-HTTPS DoH request containing an invalid SIG0 record. This action, combined with prematurely closing the connection, can cause the named...

bind: BIND: Denial of Service via invalid DNSSEC records

A flaw was found in BIND, a widely used Domain Name System DNS software. A remote attacker could exploit this vulnerability by sending a large number of specially crafted, invalid DNSSEC Domain Name System Security Extensions records to a BIND recursive resolver. This could lead to excessive...

bind9: bind: BIND 9: DNS wildcard record existence can be masked by an attacker via inapplicable NSEC records

A flaw was found in BIND 9. A remote attacker could exploit this by providing an inapplicable NSEC Next Secure record to a named resolver. This could allow the attacker to mask the existence of a victim's wildcard DNS Domain Name System record, potentially leading to a misrepresentation of DNS...

bind: BIND 9: Denial of Service via crafted query responses

A flaw was found in BIND 9. A remote attacker could send multiple copies of a single record in a query response to the named service. This could lead to increased memory usage in the negative cache, potentially causing a Denial of Service DoS due to memory exhaustion...

bind: BIND: DNS cache poisoning via malformed zone insertion

A flaw was found in BIND, a widely used Domain Name System DNS software. A remote attacker could exploit this by introducing a specially crafted, malformed DNS zone into an authoritative BIND server. This action could cause the server to incorrectly delegate authority for parts of its own...

bind: BIND: Denial of Service via malformed DNS64 responses

A flaw was found in BIND. When a resolver is configured to use DNS64, a specially crafted, malformed answer from an authoritative server can cause the named process to exit unexpectedly. This can lead to a Denial of Service DoS for clients relying on the affected resolver...

bind: BIND: Denial of Service via crafted DNSSEC reply

A flaw was found in BIND. A remote attacker, by sending a specially crafted DNSSEC-signed authoritative zone reply, can trigger an unexpected program exit in the validating resolver. This can lead to a Denial of Service DoS for the affected BIND resolver...

bind: BIND 9: Remote Denial of Service via cached SVCB/HTTPS AliasMode records

A flaw was found in BIND 9. A remote attacker can exploit this vulnerability by querying a BIND resolver for the root of a specially crafted, cached tree of SVCB/HTTPS AliasMode records. This action causes the resolver to spend a disproportionate amount of CPU time constructing the response,...
