CVE-2026-42250 MEDIUM PATCH This Month

Out-of-bounds write in bzip2's bzip2recover utility allows a local attacker to supply a specially crafted file that triggers an off-by-one error, corrupting a global buffer and crashing the process. Per the CVSS 4.0 vector (AV:L/AC:L/AT:N/PR:N/UI:N), the attack requires no privileges and no user interaction beyond the utility being invoked against a malicious file. Impact is strictly denial of service against the bzip2recover process - no confidentiality or integrity exposure - and the CVSS 4.0 score of 5.1 (Medium) reflects this constrained scope. No public exploit or active exploitation has been identified at time of analysis.

CVE-2026-8915 HIGH This Week

Out-of-bounds write in Samsung's Escargot JavaScript engine allows attacker-supplied scripts to corrupt memory through the ArrayBuffer.prototype.transfer() built-in, with high confidentiality, integrity, and availability impact (CVSS 8.8). The flaw stems from a missing length-bounds check when transferring an ArrayBuffer to a new byte length, enabling writes past the allocated buffer that can lead to remote code execution if a victim runs the malicious script. No public exploit has been identified at time of analysis, and no EPSS or CISA KEV data was provided.

CVE-2026-44988 HIGH This Week

Out-of-bounds write in LibVNCClient (shipped in the LibVNCServer project, versions 0.9.15 and earlier) lets a malicious or compromised VNC server corrupt memory in any client that connects to it. The Tight encoding decoder's Gradient filter uses fixed 2048-pixel scratch buffers but never validates the server-supplied rectangle width, so a crafted FramebufferUpdate with a width above 2048 overruns those buffers, threatening confidentiality, integrity, and availability (CVSS 8.8). There is no public exploit identified at time of analysis and it is not listed in CISA KEV; the issue is fixed by upstream commit 5b270544.

CVE-2026-48689 CRITICAL Act Now

Remote code execution in FastNetMon Community Edition through 1.2.9 stems from an off-by-one heap write in the pervasively-used dynamic_binary_buffer_t class, reachable by anyone who can send NetFlow, sFlow, IPFIX, or BGP traffic to the DDoS-detection appliance. Because the flawed buffer is exercised during BGP encoding/decoding, NetFlow template parsing, and Flow Spec NLRI construction, an unauthenticated network attacker can corrupt adjacent heap metadata and potentially execute arbitrary code. The flaw carries a critical CVSS 9.8 (AV:N/AC:L/PR:N/UI:N), but no public exploit is identified at time of analysis and it is not listed in CISA KEV.

CVE-2026-45253 HIGH This Week

Local privilege escalation in FreeBSD via the ptrace(PT_SC_REMOTE) interface allows an unprivileged user with debug access to a process to trigger arbitrary kernel code execution by abusing improperly validated parameters in syscall(2) and __syscall(2) meta-system calls. Affected releases include FreeBSD 14.3, 14.4, and 15.0 prior to their respective patch levels, and no public exploit identified at time of analysis. EPSS exploitation probability is low (0.02%) but the CVSS base score of 8.4 reflects high impact across confidentiality, integrity, and availability once a foothold exists.

Out-of-bounds write in Netatalk versions 2.0.4 through 4.4.2 stems from a missing o_len bounds check in the pull_charset_flags() character-set conversion routine, enabling remote attackers with low privileges to corrupt memory and potentially compromise confidentiality, integrity, and availability of the AFP file server. The flaw is addressed in Netatalk 4.4.3, and no public exploit has been identified at time of analysis.

Out-of-bounds write in Netatalk versions 2.0.4 through 4.4.2 affects the convert_charset() routine during null termination handling, exposing the AppleTalk/AFP server implementation to memory corruption. Authenticated remote attackers can trigger heap or stack corruption that threatens confidentiality, integrity, and availability of the host. No public exploit identified at time of analysis, and the vendor has shipped a corrective release in 4.4.3.

Heap buffer overflow write in libheif (versions ≤ 1.21.2) lets a crafted HEIF/AVIF file write 64 bytes of attacker-controlled data past a chroma-plane heap allocation during grid tile compositing. Any application using libheif to decode untrusted images - image viewers, file managers, browsers, mobile OS thumbnailers - is exposed, with CVSS 8.8 reflecting likely code execution after user-triggered file open. No public exploit identified at time of analysis, but the deterministic 64-byte fully-controlled overflow is highly favorable for exploitation.

Exploitation requires local execution of attacker-supplied script content with user interaction, but successful triggering yields high impact to confidentiality, integrity, and availability (CVSS 7.8). No public exploit identified at time of analysis and the issue is not on the CISA KEV list.
