CVE-2026-90259 btrfs: qgroup: fix a wrong length calculation in qgroup_free_reserved_data()

In the Linux kernel, the following vulnerability has been resolved: btrfs: qgroup: fix a wrong length calculation in qgroupfreereserveddata In that function, we round down the start position and round up the ending position. But during the calculation of @len, we use "roundupstart + len,...

CVE-2026-90259

CVE-2026-90259 affects the btrfs qgroup subsystem of the Linux kernel . The bug is in qgroup_free_reserved_data(), where the length calculation incorrectly uses round_up(start + len, sectorsize)—yielding the rounded-up end position rather than the rounded-up length . This produces an erroneously ...

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...

GHSA-9RM7-3QHH-H2MC 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...
