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-2026-53306

CVE-2026-53306 affects the Linux kernel tty/hvc_iucv path. The issue is an off-by-one in the number of supported devices: MAX_HVC_IUCV_LINES is 8, and hvc_iucv_devices can be 0–8. When devices == 8, a path that validates against the table size can access hvc_iucv_table[8], potentially triggering ...
