In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: fix out-of-bounds access in mmio copy helpers mt76mmiowritecopy and mt76mmioreadcopy iterate up to ALIGNlen, 4, so a length that is not a multiple of four reads past the source buffer writecopy or writes past the...

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 ...

CVE-2026-90230

CVE-2026-90230 is a heap out-of-bounds read in the Linux kernel's NVMe target (nvmet) authentication path. The function nvmet_auth_negotiate() indexes a fixed idlist[60] array using host-supplied halen/dhlen fields (both u8, max 255) without validating the transfer length, allowing a malicious or...

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...
