CVE-2026-89633

CVE-2026-89633 is a critical (CVSS 9.8) vulnerability in the Linux kernel's SMB client , specifically in the coalesce_t2() function. The root cause is that server-supplied DataOffset fields are used to compute data pointers without any validation against buffer boundaries. A small DataOffset valu...

CVE-2026-89633 smb: client: fix OOB read/write from unvalidated DataOffset in coalesce_t2()

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-2026-89622 HID: mcp2221: clear rxbuf after I2C/SMBus transfer completes

In the Linux kernel, the following vulnerability has been resolved: HID: mcp2221: clear rxbuf after I2C/SMBus transfer completes mcpi2csmbusread stores the caller-supplied buffer pointer in mcp-rxbuf for the duration of a transfer but never clears it when the transfer finishes or times out. Once...

CVE-2026-89622

CVE-2026-89622 is a write use-after-free in the Linux kernel's HID mcp2221 driver . The function mcp_i2c_smbus_read() stores a caller-supplied buffer pointer in mcp->rxbuf but fails to clear it when an I2C/SMBus transfer completes or times out. Once the caller frees the buffer, a delayed or sp...

CVE-2026-89615

CVE-2026-89615 is a buffer overflow in the Linux kernel's NTFS3 filesystem driver. In the copy_lcns loop and the redo shorten loop, page_lcns[] is indexed at j + i, where i runs up to the log record's lcns_follow. That count is validated only against the record's own length, not the target entry'...

CVE-2026-89615

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: bound pagelcns index by the log record The copylcns loop and the redo shorten loop index pagelcns at j + i, where i runs up to the log record's lcnsfollow. That count is checked only against the record's own length, not...

CVE-2026-89611

This vulnerability affects the Linux kernel NTFS driver in ntfs_attr_update_meta(), where insufficient validation of non-resident attribute offsets during sparse/non-sparse conversion allows a malicious MFT record to cause out-of-bounds writes or data overlap with mapping pairs. Red Hat describes...

CVE-2026-89607

CVE-2026-89607 affects the Linux kernel's ecryptfs module. The function parse_tag_3_packet() fails to bound encrypted_key_size against ECRYPTFS_MAX_KEY_BYTES (64) in the passphrase decryption path. When the value exceeds 64, two out-of-bounds writes corrupt the ecryptfs_auth_tok and ecryptfs_cryp...
