EUVD-2026-81936

In the Linux kernel, the following vulnerability has been resolved: net/sched: fqcodel: clamp default quantum and mtu fqcodelinit sets q-quantum = pschedmtuqdiscdevsch without clamping. A device with a huge MTU e.g. dummy with maxmtu == 0 accepting MTU 2147483634 makes pschedmtu return 0x80000000...

CVE-2026-90073 net/sched: hhf: clamp quantum before hhf_change() to avoid overflow

In the Linux kernel, the following vulnerability has been resolved: net/sched: hhf: clamp quantum before hhfchange to avoid overflow hhfinit sets q-quantum = pschedmtuqdiscdevsch with no overflow check. A device with a huge MTU e.g. dummy with maxmtu == 0 accepting MTU 2147483634 makes weight...

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...

Integer Overflow or Wraparound

Overview Affected versions of this package are vulnerable to Integer Overflow or Wraparound via the ByteArrayProtoReader32 fast path in wire-runtime/src/commonMain/kotlin/com/squareup/wire/ByteArrayProtoReader32.kt. An attacker can crash protobuf decoding by supplying a length-delimited field wit...

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...
