CVE-2026-71402

An out-of-bounds read was found in the DHCPv4 packet capture code of wicked. nicaptureinspectudpheader in src/capture.c reports the IP total length as the payload length instead of the length of the remaining UDP payload. Consequently, the DHCP option walker in the DHCPv4 client wickedd-dhcp4 rea...

darknet subscripts its layer array with an index taken from a configuration file without checking it against the array's length. The array is allocated in src-lib/darknetnetwork.cpp as xcallocnet.n, sizeofDarknet::Layer, sized to exactly the number of layer sections the file declares. The shortcu...

CVE-2026-13481

The IEEE 1588 PTP management-message parser in subsys/net/lib/ptp/tlv.c mishandles the PTPMGMTTIME management id. In tlvmgmtpostrecv, the PTPMGMTTIME case casts mgmttlv-data to a 10-byte struct ptptimestamp and reads it then byte-swaps and writes it back without first checking that the TLV data...

CVE-2026-80557 libceph: fix OOB read in decode_watchers() via missing bounds check

In the Linux kernel, the following vulnerability has been resolved: libceph: fix OOB read in decodewatchers via missing bounds check cephstartdecoding validates that structlen bytes remain in the buffer after the encoding header, but accepts structlen=0 as valid: cephdecodeneedp, end, 0, bad alwa...

CVE-2026-80557

CVE-2026-80557 is a 4-byte out-of-bounds read in the Linux kernel's libceph client, specifically in decode_watchers(). The function calls ceph_decode_32(p) without a preceding bounds check; when a malicious or compromised OSD sends an obj_list_watch_response_t with struct_len=0, the pointer equal...

kernel: Input: synaptics-rmi4 - bound the F3A keymap to the GPIO count

A flaw was found in the Linux kernel's synaptics-rmi4 input driver. The rmif3amapgpios function incorrectly allocates memory for the gpiokeymap, making it smaller than required. This allows a device reporting a specific gpiocount value to trigger an out-of-bounds read, leading to information...
