CVE-2026-53174 ovl: keep err zero after successful ovl_cache_get()

In the Linux kernel, the following vulnerability has been resolved: ovl: keep err zero after successful ovlcacheget ovliteratemerged stores PTRERRcache in err before checking ISERRcache. On success err holds the truncated cache pointer and can be returned as a bogus non-zero error. The syzbot...

CVE-2026-53174

CVE-2026-53174 affects the Linux kernel overlay filesystem (ovl). The bug in ovl_iterate_merged() stores PTR_ERR(cache) in err before validating the cache with IS_ERR(cache), so on success err may hold a truncated cache pointer and be returned as a bogus non-zero error. The repro path goes throug...

CVE-2026-53173

Summary (concrete details from provided docs): The Linux kernel component accel/ethosu contains an OOB write in ethosu_gem_cmdstream_copy_and_validate(). A local user can trigger by supplying a crafted command stream, causing memory corruption and potential instability. The issue arises in a pars...

CVE-2026-53171 accel/ethosu: fix arithmetic issues in dma_length()

In the Linux kernel, the following vulnerability has been resolved: accel/ethosu: fix arithmetic issues in dmalength dmalength derives DMA region usage from command stream values and updates regionsize: len = len + stride0 size0 + stride1 size1 regionsizeregion = max..., len + dma-offset Several...

CVE-2026-53171

The CVE affects the Linux kernel’s accel/ethosu driver. The dma_length() function can under- or overflow while deriving DMA region usage, causing region_size[] to be under-reported and potentially bypassing bounds checks in ethosu_job.c. The issue arises from arithmetic in len calculations, signe...

CVE-2026-53165

CVE-2026-53165 describes a race in the Linux kernel iomap subsystem where, during buffered read error reporting, a separate in-flight read can detach a folio and set folio->mapping to NULL before an error is reported, leading to a NULL dereference of folio->mapping in fserror_report_io(). T...

CVE-2026-53164

The CVE-2026-53164 entry concerns the Linux kernel IOMMU DMA SWIOTLB path. The vulnerability arises when iommu_dma_iova_link_swiotlb() maps an unaligned memory region and, if the middle portion is empty, calls iommu_map() with a 0 size, which the iommu_pt implementation treats as illegal, corrupt...

CVE-2026-53156

The CVE-2026-53156 entry concerns a Linux kernel vmem core use-after-free in error paths. The description specifies that several error paths call __nvmem_device_put() which may free the underlying memory and other resources, and the code may continue to use the nvmem structure. The fix is to ensu...
