CVE-2026-58058

CVE-2026-58058 : Nmap up to 7.99 is affected by an integer underflow in IPv6 extension-header parsing (ipv6_get_data_primitive in libnetutil/netutil.cc). A crafted or truncated IPv6 extension header returned by a scanned target or on-path attacker can cause the remaining-length to underflow to a ...

EUVD-2026-39978

Nmap through 7.99 does not keep the IPv6 extension-header walk within the captured packet in ipv6getdataprimitive libnetutil/netutil.cc, so the pointer advances past the buffer and the remaining-length computation underflows to a large value. A scanned target or on-path attacker returning a craft...

GHSA-3PV8-6F4R-FFG2 tar has a PAX header desynchronization issue

Summary When a tar stream contains multiple "header" entries prior to a file entry, tar-rs applies the PAX header x to the next entry in the stream, regardless of type. For example, a stream of x - L - file PAX, GNU longname, file would result in x's extensions being applied to L rather than to...

CVE-2026-31405

CVE-2026-31405 : Linux kernel media/dvb-net vulnerability — OOB read in ULE extension header tables due to 255-element lookup arrays; bounds check added for htype to ensure out-of-range SNDU is discarded. This resolves a kernel-wide issue and is reflected in OSV advisories (e.g., Root: Debian 11/...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from an unvalidated extension header type index. This vulnerability may lead to out-of-bound reads and...
