CVE-2026-12633 Out-of-bounds write in IPv6 6LoWPAN Context Option handling via unauthenticated Router Advertisement

The IPv6 neighbor-discovery code in subsys/net/ip/ipv6nbr.c processes the 6LoWPAN Context Option 6CO, RFC 6775 carried inside ICMPv6 Router Advertisements. In handlera6co the 8-bit contextlen field is taken directly from the packet and was never bounded to the RFC maximum of 128. The function...

CVE-2026-12633

CVE-2026-12633 is an out-of-bounds write in the Zephyr RTOS IPv6 neighbor-discovery code (subsys/net/ip/ipv6_nbr.c). The function handle_ra_6co() processes the 6LoWPAN Context Option (RFC 6775) from ICMPv6 Router Advertisements without bounding the 8-bit context_len field to the RFC maximum of 12...

CVE-2026-53542 Termix: Tar option injection in file-manager archive creation allows command execution on managed SSH hosts

Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. Prior to 2.3.2, the archive creation endpoint in src/backend/ssh/file-manager.ts passes selected file basenames to tar without an end-of-options marker and without making the operands...

CVE-2026-72712

A flaw was found in Nmap. A remote attacker can exploit this denial of service vulnerability by sending a specially crafted packet that includes a zero-length Transmission Control Protocol TCP option. This malformed packet forces the application to enter an infinite loop during packet processing,...

kernel: ipv6: icmp: clear skb2->cb[] in ip6_err_gen_icmpv6_unreach()

A flaw was found in the Linux kernel's IPv6 ICMP error generation. A remote attacker could send a specially crafted IPv4 ICMP error packet with a Common Internet Protocol Security Option CIPSO IP option. This could lead to incorrect handling of packet control block data when generating an IPv6 IC...

CVE-2026-76221

GitPython before 3.1.58 contains a config-name injection vulnerability in the option-name validator that allows attackers to forge arbitrary git-config directives by injecting equals signs, hash symbols, and whitespace into option names. Attackers can inject malicious option names like 'sshComman...

CVE-2026-76221

GitPython before 3.1.58 is affected by a config-name injection vulnerability in the option-name validator. The validator fails to properly sanitize option names, allowing an attacker to inject equals signs, hash symbols, and whitespace to forge arbitrary git-config directives. A crafted option na...

CVE-2026-76219 GitPython before 3.1.58 Arbitrary File Overwrite via read-tree

GitPython versions before 3.1.58 contain an arbitrary file overwrite vulnerability in IndexFile.fromtree, IndexFile.reset, and IndexFile.mergetree methods that append caller-influenced treeish strings to git read-tree without option validation or argument separation. Attackers can inject the...

CVE-2026-65609

nnn is vulnerable to Out-of-Bound write vulnerability. Due to lack of validation of attacker-controlled length fields deserialized from a session file, a crafted session file can cause nnn to write data beyond the bounds of fixed-size global buffers when loaded with the -s option. An attacker who...

vim: Fix of CVE-2026-25749

CVE-2026-25749: bound the copy of the 'helpfile' option value in gettagfname so an over-long value cannot overflow the MAXPATHL buffer, reserving room for the "tags" tail appended right after upstream 9.1.2132...

DEBIAN-CVE-2026-54552

sh provides Python process launching. Prior to 2.2.4, the uid option in sh.py performs an incomplete privilege drop on Linux and Unix-like systems. When sh runs from an elevated process and launches a command with uid set to an unprivileged user, the child changes its UID but can retain the paren...
