In the Linux kernel, the following vulnerability has been resolved: squashfs: Add dictionary size range check to prevent shift-out-of-bounds When an abnormal SquashFS image COMPOPTS flag is 1 but dictionary size is 0 is mounted, and performs shift operations using dictionarysize, the shift expone...

CVE-2026-98636

The Linux kernel contains a vulnerability in the squashfs module where mounting an abnormal SquashFS image (with COMP_OPTS set to 1 but a dictionary size of 0) triggers a shift-out-of-bounds error. This occurs because the shift exponent $n$ becomes -1, leading to an invalid shift operation during...

In the Linux kernel, the following vulnerability has been resolved: scsi: block: Fix zonescond out-of-bounds write on zone report blkrevalidatediskzones sizes the zonescond array from the disk capacity and zone size, but the index used by blkrevalidatezonecond comes from the device-driven...

CVE-2026-98635

The Linux kernel contains an out-of-bounds write vulnerability in the scsi block layer during zone reporting. The blk_revalidate_disk_zones() function sizes the zones_cond array based on disk capacity and zone size, but blk_revalidate_zone_cond() uses an index from the device-driven report_zones(...

CVE-2026-98635 scsi: block: Fix zones_cond out-of-bounds write on zone report

In the Linux kernel, the following vulnerability has been resolved: scsi: block: Fix zonescond out-of-bounds write on zone report blkrevalidatediskzones sizes the zonescond array from the disk capacity and zone size, but the index used by blkrevalidatezonecond comes from the device-driven...

CVE-2026-98634

The Linux kernel contains a vulnerability in the scsi: sd_zbc component where sd_zbc_read_zones() uses 64-bit arithmetic to compute zone counts but stores them in an unsigned int field. This results in silent truncation for counts exceeding 32 bits, causing the system to use incorrect values for ...

CVE-2026-98634 scsi: sd_zbc: Reject disks with too many zones

In the Linux kernel, the following vulnerability has been resolved: scsi: sdzbc: Reject disks with too many zones sdzbcreadzones computes the number of zones with 64-bit arithmetic and stores the result in the unsigned int nrzones field of struct zoneddiskinfo, silently truncating counts that...

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btnxpuart: Fix skb leak in nxpprocessfwdump When CONFIGDEVCOREDUMP=n, hcidevcdappend returns -EOPNOTSUPP without freeing its skb argument. This leaks the cloned skb and also prevents nxpsetindreset from being called to...

CVE-2026-98633

The Linux kernel contains a memory leak vulnerability in the Bluetooth btnxpuart component within the nxp_process_fw_dump() function. When CONFIG_DEV_COREDUMP is disabled, the hci_devcd_append() function returns -EOPNOTSUPP without freeing its skb argument , resulting in a leaked cloned skb. This...

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: mgmt: Dequeue pending meshsendsync entries on cancel In sendcancel, pending meshtx objects are removed from the hdev-meshpending list and freed via meshsendcomplete. However, if a mesh transmission was already queued...

CVE-2026-98632

A use-after-free vulnerability exists in the Linux kernel Bluetooth management component. The issue occurs because send_cancel() frees mesh_tx objects via mesh_send_complete() while the hdev->cmd_sync_work_list may still retain a raw pointer to those objects. When hci_cmd_sync_work processes t...
