UBUNTU-CVE-2026-68147

In the Linux kernel, the following vulnerability has been resolved: fscrypt: Avoid dynamic allocation in fscryptgetdevices When a blkcryptokey starts being used or is evicted, fs/crypto/ calls fscryptgetdevices to get the filesystem's list of block devices, then iterates over them and calls...

CVE-2026-68417 RDMA/siw: publish QP after initialization

In the Linux kernel, the following vulnerability has been resolved: RDMA/siw: publish QP after initialization siwcreateqp currently calls siwqpadd before the queues, CQ pointers, state, completion, and device list entry are ready. A QPN lookup can therefore reach a QP that is still being...

CVE-2026-68383

CVE-2026-68383 affects the Linux kernel drm/xe/guc component. The vulnerability arises because the scheduler keeps a pointer to the timeline name, but q->name is freed when the exec queue is freed while scheduler fences can still reference it, leading to a use-after-free. The published fix sto...

CVE-2026-68330

CVE-2026-68330 relates to the Linux kernel net/airoha NPU mailbox handling. The issue arises because airoha_npu_send_msg() always maps the mailbox buffer with DMA_TO_DEVICE, while some callers expect the NPU to write the response back into the same buffer. On non‑cache‑coherent architectures (e.g...

EUVD-2026-55369

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Return error on non-migratable faults requiring devmem Non-migratable faults that require devmem incorrectly jump to the 'out' label, which squashes the error code intended to be returned to the upper layers. Fix this by...

CVE-2026-68233

In the Linux kernel DRM/VC4 subsystem, CVE-2026-68233 addresses a use-after-free-like race where a timer callback (BO cache timer) can be rearmed by time_work during teardown. vc4_bo_cache_destroy() deletes the timer and cancels the work, but the cancelled work can rearm the timer and queue work ...

EUVD-2026-55293

In the Linux kernel, the following vulnerability has been resolved: wifi: brcmfmac: make releasescratchbuffers idempotent brcmfpciereleasescratchbuffers frees the shared.scratch and shared.ringupd DMA buffers with dmafreecoherent but does not clear the pointers afterwards, unlike the sibling...

EUVD-2026-55533

In the Linux kernel, the following vulnerability has been resolved: fscrypt: Add missing superblock check in findorinsertdirectkey The legacy 'fscryptdirectkeys' table caches master keys that are used by v1 encryption policies that have FSCRYPTPOLICYFLAGDIRECTKEY. It's just a global table for all...

CVE-2026-68148 fscrypt: Add missing superblock check in find_or_insert_direct_key()

In the Linux kernel, the following vulnerability has been resolved: fscrypt: Add missing superblock check in findorinsertdirectkey The legacy 'fscryptdirectkeys' table caches master keys that are used by v1 encryption policies that have FSCRYPTPOLICYFLAGDIRECTKEY. It's just a global table for all...

CVE-2026-68148

The CVE relates to the Linux kernel fscrypt component. A missing superblock check in fscrypt_find_or_insert_direct_key() allowed inode keys to be shared across different super_blocks, risking use-after-free of a fscrypt_direct_key and potentially enabling denial of service, information disclosure...

CVE-2026-68147 fscrypt: Avoid dynamic allocation in fscrypt_get_devices()

In the Linux kernel, the following vulnerability has been resolved: fscrypt: Avoid dynamic allocation in fscryptgetdevices When a blkcryptokey starts being used or is evicted, fs/crypto/ calls fscryptgetdevices to get the filesystem's list of block devices, then iterates over them and calls...

In the Linux kernel, the following vulnerabilities have been resolved: dmaengine: fsl-edma: Do not explicitly disable clocks in .remove The clocks in fsledmaengine::muxclk are allocated and enabled using devmclkgetenabled, which automatically cleans up these resources. However, these clocks are...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: mtd: rawnand: cadence: The issue involves fixing a situation where the NULL pointer of the DMA device was dereferenced, without ensuring that cdnsctrl-dmac was properly initialized first. The pointer dmadev was being dereferenced...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: mm/secretmem: fixed a use-after-free race condition in the fault handler. When a page fault occurs in a secret memory file created with memfdsecret2, the kernel will allocate a new folio for it, mark the underlying page as not...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Net: Ethernet: ecbhf: Fixed the dmafreecoherent function’s DMA handle. The error-prone use of dmafreecoherent takes priv-rxbuf.alloclen as the DMA handle. This could result in improper unmapping of the buffer. The DMA handle has...
