CVE-2026-58081 Heap based buffer overflow in iconv(3)

Several encoding modules, including HZ, UTF-7, VIQR, and ZW, did not properly check the size of the caller-supplied output buffer before writing converted characters. An application that uses iconv3 to convert untrusted input to or from one of the affected encodings may be vulnerable to buffer...

CVE-2026-6368

A flaw was found in glibc GNU C Library. A local attacker or application using the wordexp function with the WRDEAPPEND flag can trigger the interface to return invalid memory in the wewordv member. This invalid memory, when subsequently processed by wordfree, may cause the process to abort,...

CVE-2026-6791

A flaw was found in glibc. When processing paths that start with a tilde followed by a username, the wordexp function can be forced to allocate an excessive amount of memory on the program's stack. A remote attacker could exploit this by providing a very long username, leading to a stack exhausti...
