SUSE CVE-2026-6103

phartarnumber parses the octal size field of a TAR header into a uint32t with no overflow check. The field is 11 octal digits wide and holds values up to 0x1FFFFFFFF, so a size above 0xFFFFFFFF silently wraps. The parser then skips the wrong number of data blocks and interprets attacker-controlle...

SUSE CVE-2026-59980

hpack is an HTTP/2 Header Encoding for Python. Prior to version 4.2.0, unbounded variable integer decoding can cause run-away computation on malformed input leading to On^2 runtime, effectively blocking further processing with large enough unsanitized input. A fix is available in python-hyper/hpa...

SUSE CVE-2026-93784

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: validate IEs in cfg80211wextsiwgenie The KASAN allocation trace shows that a malformed IE buffer is stored via SIOCSIWGENIE cfg80211wextsiwgenie without any validation. The crash trace shows that a subsequent...

CVE-2026-97551

A flaw was found in the Linux kernel's XFS file system. A local user can trigger a Denial of Service DoS by forcing an unexpected filesystem shutdown. When updating parent pointer attributes, the kernel fails to properly initialize the block reservation counter, causing an integer underflow durin...

CVE-2026-18747 Integer underflow of net_buf length in the MCUmgr serial (SMP over console) transport leads to out-of-bounds read

The MCUmgr SMP-over-console transport decodes a base64 frame, reads a 16-bit packet length from it, verifies a CRC and then unconditionally strips the trailing CRC with rxctxt-nb-len -= 2U; in mcumgrserialprocessfrag subsys/mgmt/mcumgr/transport/src/serialutil.c. mcumgrserialextractlen accepted a...

CVE-2026-18747

The MCUmgr SMP-over-console transport in the Zephyr RTOS (specifically affecting CONFIG_MCUMGR_TRANSPORT_UART and CONFIG_MCUMGR_TRANSPORT_SHELL) is vulnerable to an integer underflow in mcumgr_serial_process_frag(). The system fails to properly validate declared packet lengths of 0 or 1; when the...

kernel: RDMA/siw: Reject MPA FPDU length underflow before signed receive math

A flaw was found in the Linux kernel's Soft-iWARP siw component for Remote Direct Memory Access RDMA. A remote attacker can send a specially crafted iWARP Fast Path Data Unit FPDU with a manipulated length field. This manipulation causes an integer underflow, leading to a use-after-free...
