In the Linux kernel, the following vulnerability has been resolved: dma-buf: Fix silent overflow for phys vec to sgt In case MMIO size is bigger than 4G and peer2peer DMA goes through host bridge, we trigger a code path that assigns the total linked IOVA which is greater than 4G to mappedlen...

CVE-2026-98242

A vulnerability in the Linux kernel dma-buf subsystem allows for a silent overflow when the MMIO size exceeds 4G during peer-to-peer DMA through a host bridge. The root cause is that mapped_len was declared as a 32-bit unsigned int, causing a wrap-around when accumulating size_t lengths. This tru...

CVE-2026-98240 net: ip_tunnel: initialize `options_len` before referencing options

In the Linux kernel, the following vulnerability has been resolved: net: iptunnel: initialize optionslen before referencing options The following command triggers a kernel panic: ip link add d0 type dummy; ip link set d0 up ip route add 10.30.0.0/16 \ encap ip id 300 geneveopts 4660:66:11223344 d...

CVE-2026-98240

The Linux kernel contains a vulnerability in the net: ip_tunnel component where options_len is used to calculate an option pointer before being initialized. This oversight leads to a buffer overflow during a memcpy operation, specifically when processing geneve_opts . This issue can trigger a ker...

CVE-2026-98232 scsi: core: Validate MODE SENSE lengths in scsi_cdl_enable()

In the Linux kernel, the following vulnerability has been resolved: scsi: core: Validate MODE SENSE lengths in scsicdlenable scsicdlenable uses length fields returned by MODE SENSE to locate the ATA feature mode page in a 64-byte stack buffer. A target can report a total length shorter than its...

CVE-2026-98222 KEYS: encrypted: fix integer overflow of datablob_len

In the Linux kernel, the following vulnerability has been resolved: KEYS: encrypted: fix integer overflow of databloblen encryptedkeyalloc stores databloblen in a u16. It is computed from multiple string and payload lengths. If the result exceeds U16MAX, the assignment truncates the allocation...

CVE-2026-98222

The Linux kernel contains an integer overflow vulnerability in the KEYS: encrypted subsystem. The function encrypted_key_alloc() stores datablob_len in a u16 variable. When the sum of various string and payload lengths exceeds U16_MAX , the allocation size is truncated, leading to a slab-out-of-b...

CVE-2026-98206

In the Linux kernel, the following vulnerability has been resolved: Input: cyttsp5 - clamp the HID report size before memcpy The size field comes from the device and is used as the memcpy length into responsebuf, which is CYMAXINPUT bytes...

CVE-2026-98206 Input: cyttsp5 - clamp the HID report size before memcpy

In the Linux kernel, the following vulnerability has been resolved: Input: cyttsp5 - clamp the HID report size before memcpy The size field comes from the device and is used as the memcpy length into responsebuf, which is CYMAXINPUT bytes...

CVE-2026-98206

The Linux kernel is affected by a vulnerability where the HID report size provided by a device is used as the length for a memcpy() operation into response_buf . Because the size field originates from the device without prior validation, it could lead to a buffer overflow if it exceeds CY_MAX_INP...

CVE-2026-98185 wifi: mwifiex: validate scan response extents

In the Linux kernel, the following vulnerability has been resolved: wifi: mwifiex: validate scan response extents mwifiexret80211scan subtracts the fixed response fields and the firmware-provided BSS length from resp-size without first proving that either extent fits. A short response or oversize...

CVE-2026-98184

The Linux kernel contains a heap buffer overflow in the mwifiex driver. The mwifiex_cfg80211_authenticate() function incorrectly stores the sum of req->ie_len and req->auth_data_len (both size_t) into a u16 variable. Because NL80211_ATTR_AUTH_DATA lacks a maximum length policy, the sum can ...
