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...

SUSE 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...

kernel: mm/page_alloc: clear page->private in free_pages_prepare()

A flaw was found in the Linux kernel's memory management subsystem. When pages are freed, the page-private field is not properly cleared. If these pages are later reallocated as high-order pages and split, the tail pages can retain stale page-private values. This can lead to a use-after-free...

CVE-2026-53311

A flaw was found in the FUSE Filesystem in Userspace subsystem of the Linux kernel. An uninitialized value vulnerability exists in the fusedentryrevalidate function, where it may be called with a dentry that has an uninitialized dtime field. This can lead to unpredictable system behavior or a...

CVE-2026-53294

A flaw was found in the Linux kernel's mailbox subsystem. This vulnerability occurs when the receive RX channel is aliased to the transmit TX channel with a different Memory-Mapped I/O MMIO and is not properly handled during the freeing of channels. This can lead to a double-free condition, which...

CVE-2026-36848

Gigamon GVOS v5.16.1 and earlier is affected by a Directory Traversal in the H-VUE subsystem. The root cause is in the legacy persistd web service (port 8089) of GVOS, where DownloadDbFile and UploadDbFile handlers mishandle user-supplied paths, enabling arbitrary file read/write outside the GVOS...

PT-2026-53654

Name of the Vulnerable Software and Affected Versions Gigamon GVOS versions prior to 5.16.2 Description The GVOS H-VUE subsystem contains a directory traversal flaw, which allows an attacker to access files and directories outside the intended folder. Recommendations Update Gigamon GVOS to versio...

Integer Overflow or Wraparound

Overview Affected versions of this package are vulnerable to Integer Overflow or Wraparound through the processing of a 32-bit attribute count received from a remote server in the publickey subsystem. An attacker can cause a heap buffer overflow by sending a specially crafted response that trigge...

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...
