CVE-2026-6791

CVE-2026-6791 concerns tilde expansion in wordexp within glibc. When expanding paths starting with ~username, parse_tilde extracts the username and allocates memory for it on the stack via strndupa. No bounds checks on the username length can exhaust stack space, enabling a stack-clash condition ...

EUVD-2026-55729

When expanding paths that begin with a tilde followed by a username, the internal parsetilde function extracts the username to determine the user's home directory. The implementation allocates memory for this username directly on the stack using the strndupa macro. Because the size of this...
