CVE-2026-43026

In the Linux kernel, the following vulnerability has been resolved: netfilter: ctnetlink: zero expect NAT fields when CTAEXPECTNAT absent ctnetlinkallocexpect allocates expectations from a non-zeroing slab cache via nfctexpectalloc. When CTAEXPECTNAT is not present in the netlink message, savedad...

CVE-2026-43026

CVE-2026-43026 concerns the Linux kernel netfilter ctnetlink path: when CTA_EXPECT_NAT is absent, ctnetlink_alloc_expect() can leave saved_addr and saved_proto uninitialized, risking leakage of stale data. The safe nf_ct_expect_init() in the packet path zeros these fields, and the patch adds expl...

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-2026-43005 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
