EUVD-2026-76610

In the Linux kernel, the following vulnerability has been resolved: nfsd: widen nfsdgenlrqstp address fields to sockaddrstorage struct nfsdgenlrqstp declares rqdaddr and rqsaddr as plain "struct sockaddr" 16 bytes. When an IPv6 NFS client is connected, nfsdgenlrpcstatuscomposemsg casts these fiel...

CVE-2026-89691 nfsd: clear opcnt on compound arg release to prevent OOB read

In the Linux kernel, the following vulnerability has been resolved: nfsd: clear opcnt on compound arg release to prevent OOB read nfsd4releasecompoundargs resets args-ops to the inline iops8 array when the dynamically-allocated ops buffer is freed, but leaves args-opcnt at its original value whic...

CVE-2026-89691

CVE-2026-89691 affects the Linux kernel's nfsd (NFS server) component. The root cause is that nfsd4_release_compoundargs() resets args->ops to the inline 8-element iops[] array after freeing the dynamically allocated ops buffer, but fails to clear args->opcnt, which can be up to 200 for NFS...

CVE-2026-89656

CVE-2026-89656 affects the libceph subsystem of the Linux kernel . The vulnerability resides in crush_decode() , which stores CRUSH bucket data by array slot. A malformed CRUSH map can encode a bucket id that does not match its array slot, causing the mapper to alias one bucket into another's wor...

CVE-2026-89656 libceph: reject buckets with mismatched CRUSH ids

In the Linux kernel, the following vulnerability has been resolved: libceph: reject buckets with mismatched CRUSH ids crushdecode stores bucket data by array slot, and the mapper later derives the per-bucket workspace index from the decoded bucket id. A malformed map can therefore make one bucket...

CVE-2026-89649

CVE-2026-89649 affects the Linux kernel's CephFS subsystem. The function __build_xattrs() decodes xattr blobs supplied by the Ceph metadata server (MDS) but fails to verify that the final attribute's value length does not exceed the remaining bytes in the blob — it advances the pointer with a bar...

EUVD-2026-76545

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix OOB read/write from unvalidated DataOffset in coalescet2 coalescet2 computes data pointers directly from server-supplied DataOffset fields with no validation against buffer bounds: dataareaoftgt = char...

CVE-2026-89634

CVE-2026-89634 affects the Linux kernel SMB client subsystem. The vulnerability resides in the symlink_data() error-context loop: when ErrorDataLength is near UINT32_MAX (e.g., 0xFFFFFFF9), the ALIGN(x, 8) macro overflows and wraps to 0 , causing the post-alignment bounds check to pass incorrectl...

CVE-2026-89631 smb: client: reject a tree connect response whose byte count is too small

In the Linux kernel, the following vulnerability has been resolved: smb: client: reject a tree connect response whose byte count is too small CIFSTCon bounds its strnlen over the byte area with the server's ByteCount minus two, which for ByteCount 0 or 1 goes negative as an int and converts to a...

CVE-2026-89621

CVE-2026-89621 is a Linux kernel vulnerability in the HID mcp2221 driver's mcp2221_raw_event() function. The function fails to validate the size of incoming HID reports in the MCP2221_I2C_GET_DATA path, trusting a device-supplied data[3] field as the copy length without verifying that 4 + data[3]...

CVE-2026-89583

CVE-2026-89583 affects the Linux kernel Bluetooth EIR subsystem. The function eir_get_service_data() walks advertising data for a matching Service Data UUID but incorrectly decrements eir_len by only the field's data length, omitting the length and type bytes. This shortfall compounds across skip...

CVE-2026-89542

CVE-2026-89542 affects the Linux kernel SUNRPC subsystem, specifically the gss_krb5_unwrap_v2() function used during Kerberos GSS authentication. The function reads the EC and RRC header fields at ptr+4 and ptr+6 before validating that the token is at least 16 bytes long, and its rotate_left() he...

CVE-2026-89541

CVE-2026-89541 affects the Linux kernel's SUNRPC subsystem in the function gss_unwrap_resp_priv(). The root cause is a u32 integer overflow in the RPCSEC_GSS opaque length validation: when opaque_len is near 0xffffffff, the sum offset + opaque_len wraps to a small value, bypassing the bound check...

EUVD-2026-76401

In the Linux kernel, the following vulnerability has been resolved: ocfs2: bound namelen in dlmmigraterequesthandler Patch series "ocfs2/dlm: bound peer-controlled lengths in the o2dlm". The o2dlm receive handlers trust u8 length and count fields from the wire without bounding them, so a node in ...

CVE-2026-89495

Linux kernel (ocfs2/dlm subsystem) is vulnerable to a heap out-of-bounds write in dlm_migrate_request_handler(). A peer-supplied namelen field (u8) from a DLM_MIGRATE_REQUEST message is passed unchecked to dlm_init_mle(), which memcpy()s it into a fixed 32-byte mname[] array, allowing up to ~215 ...

EUVD-2026-76400

In the Linux kernel, the following vulnerability has been resolved: ocfs2: validate lengths in dlmmiglockreshandler A node receiving a DLMMIGLOCKRES message trusts several fields of the peer-supplied dlmmigratablelockres without validation. numlocks and locknamelen are bounded only on the sending...

CVE-2026-89471 power: supply: cros_usbpd-charger: bound the EC-reported port count

In the Linux kernel, the following vulnerability has been resolved: power: supply: crosusbpd-charger: bound the EC-reported port count crosusbpdchargerprobe reads two port counts from the EC and uses one of them, numchargerports, as the loop bound when populating a fixed-size array: struct portda...

EUVD-2026-76349

In the Linux kernel, the following vulnerability has been resolved: platform/x86: ISST: Validate level in perf mask ioctls isstifgetperflevelmask and isstifgetbasefreqmask use the user-provided level as an index into perflevels via readpplevelinfo and readbflevelinfo, but neither helper validates...

CVE-2026-81014

CVE-2026-81014 is a heap out-of-bounds read in the Linux kernel's platform/x86: hp-bioscfg driver, affecting the sk_store() and kek_store() sysfs write handlers. Both functions strip a trailing newline from user input and allocate a key buffer of size length (one byte shorter), but then pass the ...

CVE-2026-81014 platform/x86: hp-bioscfg: fix heap OOB read in sk_store() and kek_store()

In the Linux kernel, the following vulnerability has been resolved: platform/x86: hp-bioscfg: fix heap OOB read in skstore and kekstore skstore and kekstore strip a trailing newline from the sysfs write before allocating the key buffer: length = count; if buflength - 1 == '\n' length--;...
