CVE-2026-90141

CVE-2026-90141 is an integer overflow in the Linux kernel IPVS FTP helper (ip_vs_ftp_get_addrport()). Decimal digits from a crafted FTP PASV/EPSV response are accumulated into a __u16 port variable and unsigned char address octets without overflow checks, causing the value to wrap and the helper ...

CVE-2026-90076

CVE-2026-90076 affects the Linux kernel 's net/sched FQ (Fair Queue) qdisc. In fq_init(), the quantum and initial_quantum values are computed from psched_mtu() without overflow protection. A network device with an extremely large MTU (e.g., a dummy device accepting MTU 2147483634) causes the 32-b...

Wire: Unauthenticated decoder crash via 32-bit length integer overflow in ByteArrayProtoReader32 (incomplete fix of CVE-2026-45799)

Wire's protobuf decoders did not consistently validate attacker-controlled length-delimited sizes against the current reader bounds before computing cursor, limit, or pointer positions. In the Kotlin runtime, ProtoAdapter.decodeByteArray and ProtoAdapter.decodeByteString use the ProtoReader32 fas...

kernel: net: qrtr: fix 32-bit integer overflow in qrtr_endpoint_post()

A flaw was found in the Linux kernel's qrtr network component. On 32-bit systems, a 32-bit integer overflow can occur in the qrtrendpointpost function when processing an incoming packet. This overflow can bypass a size validation check, leading to an out-of-bounds write and causing the kernel to...

libvirt: Integer overflow in NodeGetFreePages RPC handler leading to heap buffer overflow

A flaw was found in libvirt. An unprivileged local user could exploit an integer overflow vulnerability in the NodeGetFreePages RPC handler. This flaw allows crafted values to bypass a size check, leading to an undersized memory buffer. Subsequently, real NUMA node data can overwrite this buffer...

github.com/klauspost/compress: klauspost/compress: Denial of Service via integer overflow in dictionary processing

A flaw was found in the klauspost/compress package. A remote attacker can exploit this vulnerability by supplying a specially crafted compression dictionary with an excessively large repeat value, triggering an integer overflow. When the dictionary is subsequently processed, this overflow leads t...
