CVE-2026-22185

OpenLDAP LMDB mdb_load Heap Buffer Underflow in readline()

OpenLDAP Lightning Memory-Mapped Database (LMDB) versions 0.9.14 before 0.9.34, prior to commit 8e1fda8, contain a heap buffer underflow in the readline() function of mdb_load. When processing malformed input containing an embedded NUL byte, an unsigned offset calculation can underflow and cause an out-of-bounds read of one byte before the allocated heap buffer. This can cause mdb_load to crash, leading to a limited denial-of-service condition.

CVE-2025-34457

wb2osz/direwolf <= 1.8.1 Stack-based Buffer Overflow DoS

wb2osz/direwolf (Dire Wolf) versions up to and including 1.8.1, prior to commit 694c954, contain a stack-based buffer overflow vulnerability in the function kiss_rec_byte() located in src/kiss_frame.c. When processing crafted KISS frames that reach the maximum allowed frame length (MAX_KISS_LEN), the function appends a terminating FEND byte without reserving sufficient space in the stack buffer. This results in an out-of-bounds write followed by an out-of-bounds read during the subsequent call to kiss_unwrap(), leading to stack memory corruption or application crashes. This vulnerability may allow remote unauthenticated attackers to trigger a denial-of-service condition.

CVE-2026-116197

Contrast 1.21.0 before 1.25.0 Credential Leak via imagepuller Wildcard Registry Selection

Edgeless Systems Contrast from 1.21.0 before 1.25.0 contains a non-deterministic registry selection flaw in imagepuller that can prefer wildcard configuration entries over concrete domain matches. When a pull configuration lists both a concrete domain and its parent wildcard, registry credentials, CA bundles, or mirror settings intended for the wildcard may be applied to the concrete registry, leaking credentials or pull metadata.

vLLM 0.20.1 before 0.29.0 DoS and GPU Out-of-Bounds Write via stop_token_ids

vLLM from 0.20.1 before 0.29.0 contains an improper input validation vulnerability that allows remote attackers to crash the engine by supplying out-of-vocabulary stop_token_ids. Attackers can send OpenAI chat, completion, generate, or batch requests with invalid IDs to terminate the engine or write outside the V2 runner's logits buffer.

ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 Stack Buffer Overflow via bzip2 Compressed Images

ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 contains a stack-based buffer overflow in the handling of bzip2 compressed images. Attackers can supply a crafted image using bzip2 compression to overwrite stack memory during decoding, causing crashes or memory corruption.

CVE-2026-98952

pfcp: make sure the SEID is linear before reading it

In the Linux kernel, the following vulnerability has been resolved: pfcp: make sure the SEID is linear before reading it pfcp_encap_recv() only makes sure that the UDP header and the 4 byte PFCP header are in the linear area. When the S flag is set, pfcp_session_recv() then reads the 8 byte SEID that follows, which is not covered by the pskb_may_pull() check. A short PFCP packet with the S flag set, or one whose session header lies in a fragment, therefore makes pfcp_session_recv() read beyond the end of the packet data, and whatever it finds there is stored in the tunnel metadata that flower later classifies on. Pull up to the end of the SEID before reading it, and drop packets that are too short to contain it. Reload the header pointer afterwards since pskb_may_pull() may reallocate the skb head. Use offsetofend() rather than sizeof(struct pfcphdr_session): the structure is not packed, so its size is 16 bytes because of the alignment of the __be64 member, while the header on the wire is only 12 bytes, and valid session messages would be dropped.
