In the Linux kernel, the following vulnerability has been resolved: RDMA/bnxtre: zero shared page before exposing to userspace bnxtreallocucontext allocates uctx-shpg via getfreepageGFPKERNEL. The buddy allocator does not zero pages without GFPZERO, so the page contains stale kernel data from...

CVE-2026-68768

hashcat contains a heap-based buffer overflow out-of-bounds write in the outfilewrite function in src/outfile.c. When assembling output into a fixed-size buffer HCBUFSIZLARGE, 16 MB, the function sequentially appends the username, separator, hash, and plaintext via memcpy without validating that...

CVE-2026-70626

NLTK versions before 3.9.4 contain a symlink escape vulnerability in CorpusReader.open that allows local attackers to read arbitrary files outside the corpus root. The vulnerability exists because path validation is lexical and does not account for symlink resolution, enabling attackers to place...

CVE-2026-68767

hashcat's fgetl function in src/filehandling.c writes a null terminator one byte past the caller's buffer when an input line is exactly the buffer length. Attackers can trigger this out-of-bounds heap write by providing a hash file, potfile, or wordlist containing a line of exactly HCBUFSIZLARGE...

CVE-2026-68766

hashcat fails to restrict command-line options when parsing restore files, allowing attackers to inject output-redirecting options like --outfile and --potfile-path. Attackers can craft restore files with malicious options to append attacker-controlled content to arbitrary files, enabling code...

CVE-2026-66393

NLTK versions before 3.9.4 contain an unbounded recursion vulnerability in JSONTaggedDecoder.decodeobj that allows attackers to cause denial of service by supplying deeply nested JSON structures. Attackers can craft JSON payloads exceeding the recursion limit to trigger an unhandled RecursionErro...

CVE-2026-65915
