CVE-2026-79771

Nokogiri versions before 1.19.3 are affected by a memory leak in the XSLT Stylesheet transform method. The root cause is heap allocations leaking when Ruby strings containing null bytes are passed as transform parameters. An unauthenticated, network-based attacker can trigger this by supplying cr...

CVE-2026-15310

This vulnerability affects Python's zipfile module, specifically the decompression path for bzip2, LZMA, and Zstandard compressed members. The root cause is that these decompression routines use an attacker-controlled size to pre-allocate memory without a max_length bound , effectively defeating ...

CVE-2026-79902

A flaw was found in the Seattle FilmWorks plugin in GIMP. When processing a specially crafted SFW image file, the plugin allocates a Variable-Length Array VLA on the stack without integer overflow checks, causing an unbounded stack allocation. This issue leads to an application crash, resulting i...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling through osslcmpmsgcheckupdate in crypto/cmp/cmpvfy.c. An attacker can drive unbounded memory growth by repeatedly sending CMP messages with unique extraCerts that are rejected during...

AZL-97944 CVE-2026-63074 affecting package openssl for versions less than 3.3.7-6

Issue summary: The OpenSSL Certificate Management Protocol CMP caches additional certificates extraCerts sent in a CMP message, but never expunges them for instance if they are invalid. If a server reuses an OSSLCMPCTX frequently, this cache of extraCerts may grow unboundedly, and a malicious...

CVE-2026-74728

A flaw was found in the Linux kernel's XFS filesystem. When the system attempts to allocate memory for an XFS buffer and that allocation fails, the xfsbuffree function is called with a null buffer address. This leads to a null pointer dereference, causing the kernel to crash. This vulnerability c...

libgit2: libgit2: Denial of Service via Unbounded Memory Allocation

A flaw was found in libgit2. The gitdeltaapply function incorrectly trusts an attacker-controlled size value from a delta object header, which is used for memory allocation before proper validation of delta instructions. A remote attacker or local user can supply malicious pack data, for example,...
