Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: The issue arises from the PCI AER model being an awkward fit for CXL error handling. When a PCI device escalates to link reset to recover from an AER event, the same reset on CXL resul...
bind9: Querying RFC 1918 reverse zones may cause an assertion failure when “nxdomain-redirect” is enabled
A flaw was found in the bind package which may result in a Denial of Service in named process. This is a result of a reachable assertion, leading named to prematurely terminate when both conditions are met: nxdomain-redirect for the queried domain is configured and the resolver receives a PTR...
bind9: Preparing an NSEC3 closest encloser proof can exhaust CPU resources
A flaw was found in bind9. By flooding a DNSSEC resolver with responses coming from a DNSEC-signed zone using NSEC3, an attacker can lead the targeted resolver to a CPU exhaustion, further leading to a Denial of Service on the targeted host. This vulnerability applies only for systems where DNSSE...
bind9: Enabling both DNS64 and serve-stale may cause an assertion failure during recursive resolution
A flaw was found in the bind package. This issue may allow an attacker to query in a DNS64 enabled resolver node with a domain name triggering a server-stale data, triggering a code assertion, and resulting in a crash of named processes. This can allow a remote unauthenticated user to cause a...
bind9: Specific recursive query patterns may lead to an out-of-memory condition
A flaw was found in the named application, part of the bind9 package, which uses a cache database to speeds up DNS queries. To maintain its efficiency when running as a recursive name resolver, named performs a cache database clean up under certain conditions. This issue may allow an attacker to...
bind9: Parsing large DNS messages may cause excessive CPU load
A flaw was found in the bind package. This issue may allow a remote attacker with no specific privileges to craft a specially long DNS message leading to an excessive and uncontrolled CPU usage, the server being unavailable, and a Denial of Service...

bind9: KeyTrap - Extreme CPU consumption in DNSSEC validator
Processing specially crafted responses coming from DNSSEC-signed zones can lead to uncontrolled CPU usage, leading to a Denial of Service in the DNSSEC-validating resolver side. This vulnerability applies only for systems where DNSSEC validation is enabled...

K000139084: DNS vulnerability CVE-2023-50868
Security Advisory Description The Closest Encloser Proof aspect of the DNS protocol in RFC 5155 when RFC 9276 guidance is skipped allows remote attackers to cause a denial of service CPU consumption for SHA-1 computations via DNSSEC responses in a random subdomain attack, aka the "NSEC3" issue. T...

K000138990: BIND vulnerability CVE-2023-4408
Security Advisory Description The DNS message parsing code in named includes a section whose computational complexity is overly high. It does not cause problems for typical DNS traffic, but crafted queries and responses may cause excessive CPU load on the affected named instance by exploiting thi...
K000138991: BIND vulnerability CVE-2023-6516
Security Advisory Description To keep its cache database efficient, named running as a recursive resolver occasionally attempts to clean up the database. It uses several methods, including some that are asynchronous: a small chunk of memory pointing to the cache element that can be cleaned up is...
