CVE-2026-55200 libssh2 - Out-of-Bounds Write via Unchecked packet_length in transport.c

libssh2 1.11.1, fixed in commit 97acf3d, contains an out-of-bounds write vulnerability in ssh2transportread that fails to enforce upper bounds on packetlength field. Remote attackers can send crafted SSH packets with excessively large packetlength values to corrupt heap memory and achieve remote...

Improper Input Validation

hono is vulnerable to Improper Input Validation. The vulnerability is due to trusting the client-supplied Content-Length header instead of validating the actual request body size, which allows an attacker to bypass configured body size limits by declaring a smaller content length while sending a...

xorg-x11-server: xorg-x11-server-Xwayland: xorg-x11-server: stack buffer overflow in font alias resolution due to libXfont2 name length mismatch

A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. A mismatch between the X server and the libXfont2 library's maximum font name length can cause a stack buffer overflow during font alias resolution. The server allocates a 256 byte stack buffer but libXfont2's alias...

CVE-2026-10641 Out-of-bounds write in Bluetooth HFP Hands-Free CIND indicator parsing (cind_handle_values)

Zephyr's Bluetooth Classic Hands-Free Profile HFP Hands-Free role parser subsys/bluetooth/host/classic/hfphf.c contains an out-of-bounds write. During Service Level Connection setup the HF sends AT+CIND=? and parses the AG's +CIND: response in cindhandle, which assigns a per-entry counter index a...

kernel: libceph: prevent potential out-of-bounds reads in handle_auth_done()

In the Linux kernel, the following vulnerability has been resolved: libceph: prevent potential out-of-bounds reads in handleauthdone Perform an explicit bounds check on payloadlen to avoid a possible out-of-bounds access in the callout. idryomov: changelog...

kernel: netfilter: xt_tcpmss: check remaining length before reading optlen

A flaw was found in the Linux kernel, specifically within the netfilter: xttcpmss module. A remote attacker could exploit this vulnerability by sending a specially crafted TCP packet. The TCP option parser does not properly validate the remaining option length, which results in an out-of-bounds...

kernel: netfilter: nf_conntrack_h323: check for zero length in DecodeQ931()

A flaw was found in the Linux kernel's netfilter subsystem, specifically within the nfconntrackh323 module. This vulnerability occurs in the DecodeQ931 function when processing a zero-length value from a packet. An integer underflow during a length calculation results in a large, incorrect value...
