CVE Vulnerability Catalog

It was discovered that a systemd service using the DynamicUser property can gain new privileges through the execution of SUID binaries, allowing creation of binaries owned by the service's transient group with the setgid bit set. A local attacker may exploit this flaw to access resources that will be.

Several vulnerabilities have been discovered and fixed in the upstream libvips dependency, two rated as high severity using CVSSv4. Versions of sharp prior to 0.35.0 processing untrusted input are affected.

Repeated use of the Unpacker after an error occurs may cause the process to crash with a SEGV. If the Unpacker is used repeatedly to unpack untrusted input from external sources, it may be vulnerable to a DoS attack.

A vulnerability in the virtio-gpu module of the Linux kernel involves an incorrect overflow check when allocating 2D images. This flaw can lead to a buffer overflow, potentially enabling privilege escalation or system crash.

A vulnerability in the DNS protocol, related to the Closest Encloser Proof aspect in RFC 5155 (when RFC 9276 guidance is skipped), allows remote attackers to cause a denial of service (DoS) by triggering excessive CPU consumption for SHA-1 computations. The attack involves sending DNSSEC responses in a random subdomain attack, known as the NSEC3 issue.

A divide-by-zero error was discovered in py-lmdb 0.97 in the mdb_env_open2 function when mdb_env_read_header obtains a zero value for a certain size field. This issue can be triggered by supplying a crafted data.mdb file.

This is a residual of GHSA-g5vv-9gxw-82hx / CVE-2026-87819. The 3.1.60 fix made Actor._from_string regex-free, but parse_actor_and_date still runs _re_actor_epoch on the same author/committer/tagger line one step earlier. That pattern backtracks quadratically when the trailing epo...
