CVE-2026-64112

In the Linux kernel, the following vulnerability has been resolved: rbd: eliminate a race in lockdwork draining on unmap Given how rbdlockaddrequest and rbdimgexclusivelock are written, lockdwork may be requeued more than it's actually needed: for example in case a new I/O request comes in while ...

CVE-2026-64112

The CVE-2026-64112 issue affects the Linux kernel’s RBD path (rbd_lock_add_request/rbd_img_exclusive_lock) where lock_dwork can be (re)queued more than needed, enabling a TOCTOU race during image unmapping. The problem arises when a new I/O request arrives during rbd_acquire_lock(), or in maybe_k...

CVE-2026-63950

Summary: CVE-2026-63950 pertains to the Linux kernel mm/rmap path. The issue arose from not reinitializing nr_pages at the start of each loop in try_to_unmap_one, allowing a value from a previous folio_unmap_pte_batch() to be reused in a later iteration. This could cause corruption of folio refco...

CVE-2026-31735

In the Linux kernel, the following vulnerability has been resolved: iommupt: Fix short gather if the unmap goes into a large mapping unmap has the odd behavior that it can unmap more than requested if the ending point lands within the middle of a large or contiguous IOPTE. In this case the gather...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from the lack of an unmap operation when the zerofsgetextentcompressedlen function fails, which could lead to a...

DEBIAN-CVE-2022-49336

In the Linux kernel, the following vulnerability has been resolved: drm/etnaviv: check for reaped mapping in etnaviviommuunmapgem When the mapping is already reaped the unmap must be a no-op, as we would otherwise try to remove the mapping twice, corrupting the involved data structures...

CVE-2022-49336

CVE-2022-49336 concerns the Linux kernel, specifically the DRM subsystem driver etnaviv. The vulnerability arises in etnaviv_iommu_unmap_gem: if a mapping has already been reaped, the unmap operation must be a no-op to avoid removing the mapping twice and corrupting kernel data structures. The is...
