CVE-2026-58051
libssh2 through 1.11.1 grows its publickey list with SSH2REALLOC but does not zero-initialize new entries before parsing populates them, so a parse failure reaching the cleanup path leaves libssh2publickeylistfree operating on an uninitialized entry. A malicious SSH server offering the publickey...
CVE-2026-58050
libssh2 through 1.11.1 reads an attacker-controlled 32-bit attribute count from a publickey-subsystem response and uses it in the allocation numattrs sizeoflibssh2publickeyattribute without bounds checking, so on 32-bit platforms the multiplication overflows to an undersized buffer. A malicious S...

CVE-2026-58051
CVE-2026-58051 affects libssh2 up to version 1.11.1. The vulnerability arises because libssh2 grows its publickey list using SSH2_REALLOC but does not zero-initialize the newly allocated entries before parsing populates them. If parsing fails and the code path cleans up, libssh2_publickey_list_fr...
CVE-2026-58050
CVE-2026-58050 affects libssh2 up to 1.11.1. The publickey subsystem reads an attacker-controlled 32-bit attribute count and uses it in the allocation num_attrs * sizeof(libssh2_publickey_attribute) without bounds checking. On 32-bit platforms, this multiplication can overflow, producing an under...
