CVE-2026-43006

A flaw was found in the Linux kernel's iouring subsystem. A local attacker can exploit a vulnerability in the ioimportfixed function by importing a zero-length fixed buffer. This can lead to an out-of-bounds read from slab memory, potentially resulting in information disclosure or a denial of...

CVE-2026-43005

A flaw was found in the Linux kernel's tps53679 hwmon driver. When the i2csmbusreadblockdata function returns a zero-length read, the tps53679identifychip function attempts to access memory before the allocated buffer. This out-of-bounds read could lead to information disclosure or a denial of...

CVE-2026-43005

In the Linux kernel, the following vulnerability has been resolved: hwmon: tps53679 Fix array access with zero-length block read i2csmbusreadblockdata can return 0, indicating a zero-length read. When this happens, tps53679identifychip accesses bufret - 1 which is buf-1, reading one byte before t...

CVE-2026-43006

In the Linux kernel, the following vulnerability has been resolved: iouring/rsrc: reject zero-length fixed buffer import validatefixedrange admits bufaddr at the exact end of the registered region when len is zero, because the check uses strict greater-than bufend imu-ubuf + imu-len. ioimportfixe...

CVE-2026-43017 Bluetooth: MGMT: validate mesh send advertising payload length

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: MGMT: validate mesh send advertising payload length meshsend currently bounds MGMTOPMESHSEND by total command length, but it never verifies that the bytes supplied for the flexible advdata array actually match the...

CVE-2026-43017

CVE-2026-43017 concerns the Linux kernel Bluetooth MGMT mesh path. It fixes missing validation of adv_data_len in mesh_send, which could allow out-of-bounds access in queued commands. The description and connected advisories indicate: affected software is the Linux kernel; root cause is failure t...

In the Linux kernel, the following vulnerability has been resolved: iouring/rsrc: reject zero-length fixed buffer import validatefixedrange admits bufaddr at the exact end of the registered region when len is zero, because the check uses strict greater-than bufend imu-ubuf + imu-len. ioimportfixe...

CVE-2026-43006

In the Linux kernel, the following vulnerability has been resolved: iouring/rsrc: reject zero-length fixed buffer import validatefixedrange admits bufaddr at the exact end of the registered region when len is zero, because the check uses strict greater-than bufend imu-ubuf + imu-len. ioimportfixe...

CVE-2026-43006

CVE-2026-43006 (Linux kernel io_uring rsr/rsrc): A zero-length fixed-buffer import in io_import_fixed() could trigger a slab-out-of-bounds read due to a boundary check that allows len == 0 to be processed. The underlying issue is in validate_fixed_range(), which permits buf_addr at the end of the...

CVE-2026-43006 io_uring/rsrc: reject zero-length fixed buffer import

In the Linux kernel, the following vulnerability has been resolved: iouring/rsrc: reject zero-length fixed buffer import validatefixedrange admits bufaddr at the exact end of the registered region when len is zero, because the check uses strict greater-than bufend imu-ubuf + imu-len. ioimportfixe...

CVE-2026-43006 io_uring/rsrc: reject zero-length fixed buffer import

In the Linux kernel, the following vulnerability has been resolved: iouring/rsrc: reject zero-length fixed buffer import validatefixedrange admits bufaddr at the exact end of the registered region when len is zero, because the check uses strict greater-than bufend imu-ubuf + imu-len. ioimportfixe...

CVE-2026-43005 hwmon: (tps53679) Fix array access with zero-length block read

In the Linux kernel, the following vulnerability has been resolved: hwmon: tps53679 Fix array access with zero-length block read i2csmbusreadblockdata can return 0, indicating a zero-length read. When this happens, tps53679identifychip accesses bufret - 1 which is buf-1, reading one byte before t...

CVE-2026-43005

CVE-2026-43005 affects the Linux kernel hwmon driver for tps53679. The bug arises when i2c_smbus_read_block_data() returns 0 (zero-length read); tps53679_identify_chip() then accesses buf[ret-1] (buf[-1]), causing an out-of-bounds read. The fix changes the check from ret < 0 to ret
