SUSE 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...
