CVE-2026-53171

A flaw was found in the Linux kernel's accel/ethosu driver. The dmalength function, responsible for calculating Direct Memory Access DMA region usage, contains several arithmetic issues. These issues, including potential underflows and overflows during calculations, can lead to an under-reporting...

CVE-2026-53173

A flaw was found in the Linux kernel's accel/ethosu component. A local user can exploit this vulnerability by providing a specially crafted command stream, which causes an out-of-bounds write in memory. This memory corruption can lead to system instability, causing a denial of service or...

CVE-2026-53169

A flaw was found in the Linux kernel's accel/ethosu driver. An unprivileged local user with access to the Direct Rendering Manager DRM device could submit a specific command NPUOPRESIZE that the driver does not properly handle. This could lead to excessive kernel log spam and, if the paniconwarn...

SUSE CVE-2026-53172

In the Linux kernel, the following vulnerability has been resolved: accel/ethosu: fix IFM region index out-of-bounds in command stream parser NPUSETIFMREGION extracts the region index with param & 0x7f, giving a maximum value of 127. However regionsize and outputregion in struct...

CVE-2026-53170

A flaw was found in the Linux kernel's accel/ethosu driver. A local attacker could exploit a vulnerability where DMA commands with uninitialized length are not properly handled. By omitting a specific DMA length setup command and issuing a DMA start command, a user could bypass bounds checks,...

CVE-2026-53172

In the Linux kernel, the following vulnerability has been resolved: accel/ethosu: fix IFM region index out-of-bounds in command stream parser NPUSETIFMREGION extracts the region index with param & 0x7f, giving a maximum value of 127. However regionsize and outputregion in struct...

CVE-2026-53169: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: accel/ethosu: reject NPUOPRESIZE commands from userspace NPUOPRESIZE is a U85-only command that the driver does not yet implement. The existing WARNON1 placeholder fires unconditionally whenever userspace submits this command via...

CVE-2026-53172: Out-of-bounds Read

In the Linux kernel, the following vulnerability has been resolved: accel/ethosu: fix IFM region index out-of-bounds in command stream parser NPUSETIFMREGION extracts the region index with param & 0x7f, giving a maximum value of 127. However regionsize and outputregion in struct...

CVE-2026-53171: Undefined Security Weakness

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-2026-53173: Out-of-bounds Write

In the Linux kernel, the following vulnerability has been resolved: accel/ethosu: fix OOB write in ethosugemcmdstreamcopyandvalidate The command stream parsing loop increments the index variable a second time when a 64-bit command word is encountered bit 14 set, but does not re-check the loop bou...

CVE-2026-53170: Use of Uninitialized Resource

In the Linux kernel, the following vulnerability has been resolved: accel/ethosu: reject DMA commands with uninitialized length cmdstateinit initializes the command state with memset0xff, leaving dma-len at U64MAX to signal missing setup. The only setter is NPUSETDMA0LEN; if userspace omits this...
