https://notcve.org/view.php?id=CVE-2023-3212
A NULL pointer dereference issue was found in the gfs2 file system in the Linux kernel. It occurs on corrupt gfs2 file systems when the evict code tries to reference the journal descriptor structure after it has been freed and set to NULL. A privileged local user could use this flaw to cause a kernel panic. A NULL pointer dereference flaw was found in the gfs2 file system in the Linux kernel.

CVSS: 7.5EPSS: 0%CPEs: 21EXPL: 0CVE-2023-2911 – Exceeding the recursive-clients quota may cause named to terminate unexpectedly when stale-answer-client-timeout is set to 0
https://notcve.org/view.php?id=CVE-2023-2911
If the `recursive-clients` quota is reached on a BIND 9 resolver configured with both `stale-answer-enable yes;` and `stale-answer-client-timeout 0;`, a sequence of serve-stale-related lookups could cause `named` to loop and terminate unexpectedly due to a stack overflow. This issue affects BIND 9 versions 9.16.33 through 9.16.41, 9.18.7 through 9.18.15, 9.16.33-S1 through 9.16.41-S1, and 9.18.11-S1 through 9.18.15-S1. • http://www.openwall.com/lists/oss-security/2023/06/21/6 https://kb.isc.org/docs/cve-2023-2911 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/SEFCEVCTYEMKTWA7V7EYPI5YQQ4JWDLI https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/U3K6AJK7RRSR53HRF5GGKPA6PDUDWOD2 https://security.netapp.com/advisory/ntap-20230703-0010 https://www.debian.org/security/2023/dsa-5439 • CWE-787: Out-of-bounds Write •
CVSS: 7.5EPSS: 0%CPEs: 13EXPL: 0CVE-2023-2829 – Malformed NSEC records can cause named to terminate unexpectedly when synth-from-dnssec is enabled
https://notcve.org/view.php?id=CVE-2023-2829
A `named` instance configured to run as a DNSSEC-validating recursive resolver with the Aggressive Use of DNSSEC-Validated Cache (RFC 8198) option (`synth-from-dnssec`) enabled can be remotely terminated using a zone with a malformed NSEC record. This issue affects BIND 9 versions 9.16.8-S1 through 9.16.41-S1 and 9.18.11-S1 through 9.18.15-S1. • https://kb.isc.org/docs/cve-2023-2829 https://security.netapp.com/advisory/ntap-20230703-0010 •
CVSS: 7.5EPSS: 0%CPEs: 21EXPL: 0CVE-2023-2828 – named's configured cache size limit can be significantly exceeded
https://notcve.org/view.php?id=CVE-2023-2828
Every `named` instance configured to run as a recursive resolver maintains a cache database holding the responses to the queries it has recently sent to authoritative servers. The size limit for that cache database can be configured using the `max-cache-size` statement in the configuration file; it defaults to 90% of the total amount of memory available on the host. When the size of the cache reaches 7/8 of the configured limit, a cache-cleaning algorithm starts to remove expired and/or least-recently used RRsets from the cache, to keep memory use below the configured limit. It has been discovered that the effectiveness of the cache-cleaning algorithm used in `named` can be severely diminished by querying the resolver for specific RRsets in a certain order, effectively allowing the configured `max-cache-size` limit to be significantly exceeded. This issue affects BIND 9 versions 9.11.0 through 9.16.41, 9.18.0 through 9.18.15, 9.19.0 through 9.19.13, 9.11.3-S1 through 9.16.41-S1, and 9.18.11-S1 through 9.18.15-S1. A vulnerability was found in BIND. The effectiveness of the cache-cleaning algorithm used in named can be severely diminished by querying the resolver for specific RRsets in a certain order, effectively allowing the configured max-cache-size limit to exceed significantly. • http://www.openwall.com/lists/oss-security/2023/06/21/6 https://kb.isc.org/docs/cve-2023-2828 https://lists.debian.org/debian-lts-announce/2023/07/msg00021.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/SEFCEVCTYEMKTWA7V7EYPI5YQQ4JWDLI https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/U3K6AJK7RRSR53HRF5GGKPA6PDUDWOD2 https://security.netapp.com/advisory/ntap-20230703-0010 https://www.debian.org/security/2023/dsa-5439& • CWE-770: Allocation of Resources Without Limits or Throttling •
