CVE-2026-98725

The Linux kernel contains an out-of-bounds write vulnerability in the nvmet_auth_challenge() function within the nvmet-auth component. The root cause is that the output buffer is received as a void pointer , causing sizeof(*d) to evaluate to one under GCC . This results in an undercount of the fi...

CVE-2026-98725 nvmet-auth: fix out-of-bounds write in nvmet_auth_challenge()

In the Linux kernel, the following vulnerability has been resolved: nvmet-auth: fix out-of-bounds write in nvmetauthchallenge nvmetauthchallenge receives its output buffer as a void pointer. sizeofd therefore evaluates to one with GCC and undercounts the fixed challenge header by 15 bytes. A shor...

CVE-2026-98724 nvmet: pci-epf: reject too-short SGL segments

In the Linux kernel, the following vulnerability has been resolved: nvmet: pci-epf: reject too-short SGL segments The host controls an SGL segment's length. A nonzero length smaller than one SGL descriptor makes nrdescs zero, so nvmetpciepfgetsglsegment reads the type byte of sgls-1 outside the...

CVE-2026-98724

The Linux kernel contains a vulnerability in the nvmet driver related to pci-epf SGL segments. A host-controlled SGL segment length that is nonzero but smaller than a single SGL descriptor causes nr_descs to become zero. This leads the function nvmet_pci_epf_get_sgl_segment() to perform an out-of...

CVE-2026-98723

The Linux kernel contains a vulnerability in the nvmet subsystem where the hostid is incorrectly copied into the controller. Due to a sequence error in the nvmet_alloc_ctrl() implementation, nvmet_ctrl_init_pr() snapshots a nil UUID into per-controller per-namespace reservation references because...

In the Linux kernel, the following vulnerability has been resolved: mtd: block2mtd: Fix divide error when erasesize is zero The erase size is parsed from the "block2mtd" module parameter and can be set to zero. adddevice then evaluates if size % erasesize with a zero divisor, which triggers a...

CVE-2026-98722

The Linux kernel contains a vulnerability in the mtd: block2mtd module where a divide error occurs if the erase_size module parameter is set to zero. The add_device() function performs a modulo operation (size % erase_size) without first validating that erase_size is non-zero, leading to a kernel...

CVE-2026-98721 mtd: rawnand: cadence: Initialize IRQ state before requesting IRQ

In the Linux kernel, the following vulnerability has been resolved: mtd: rawnand: cadence: Initialize IRQ state before requesting IRQ The Cadence NAND interrupt handler uses both the IRQ lock and completion object. Registering the IRQ before initializing them leaves a window in which a pending...

CVE-2026-98721

The Linux kernel contains a vulnerability in the mtd: rawnand: cadence driver. The issue arises because the Cadence NAND interrupt handler uses both an IRQ lock and a completion object , but these are registered before being properly initialized. This sequence creates a race condition where a pen...
