In the Linux kernel, the following vulnerability has been resolved:

nvmet-rdma: handle inline data with a nonzero offset

nvmet_rdma_use_inline_sg() maps the host-controlled inline data offset into the per-command inline scatterlist. The bounds check admits any offset with off + len <= inline_data_size, but the mapping still assumes the data begins in the first inline page:

sg->offset = off; sg->length = min_t(int, len, PAGE_SIZE - off);

When a port is configured with inline_data_size > PAGE_SIZE (settable up to max(SZ_16K, PAGE_SIZE)), an offset in (PAGE_SIZE, inline_data_size] makes "PAGE_SIZE - off" underflow, so sg->length is set to ~4 GiB and the block backend reads far past the first inline page. num_pages(len) also ignores the offset, so an in-bounds offset whose [off, off+len) span crosses a page boundary under-counts the scatterlist.

Map the offset properly: split it into a page index and an in-page offset, start the scatterlist at that page, and size the page count from page_off + len. Because the request scatterlist may now start at inline_sg[page_idx] rather than inline_sg[0], generalize the inline-SGL identity test in nvmet_rdma_release_rsp() to a range test; otherwise the persistent inline scatterlist is mistaken for an allocated one and nvmet_req_free_sgls() frees an inline page (and warns in free_large_kmalloc()).

OESA-2026-3703 — kernel security update

Affected: openEuler:24.03-LTS-SP1: kernel

The Linux Kernel, the operating system core itself. Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

ASoC: qcom: Fix sc7280 lpass potential buffer overflow

Case values introduced in commit 5f78e1fb7a3e ("ASoC: qcom: Add driver support for audioreach solution") cause out of bounds access in arrays of sc7280 driver data (e.g. in case of RX_CODEC_DMA_RX_0 in sc7280_snd_hw_params()).

Redefine LPASS_MAX_PORTS to consider the maximum possible port id for q6dsp as sc7280 driver utilizes some of those values.

Found by Linux Verification Center (linuxtesting.org) with SVACE.(CVE-2025-37979)

In the Linux kernel, the following vulnerability has been resolved:

net: usb: asix_devices: Fix PHY address mask in MDIO bus initialization

Syzbot reported shift-out-of-bounds exception on MDIO bus initialization.

The PHY address should be masked to 5 bits (0-31). Without this mask, invalid PHY addresses could be used, potentially causing issues with MDIO bus operations.

Fix this by masking the PHY address with 0x1f (31 decimal) to ensure it stays within the valid range.(CVE-2025-38736)

In the Linux kernel, the following vulnerability has been resolved:

crypto: af_alg - Fix page reassignment overflow in af_alg_pull_tsgl

When page reassignment was added to af_alg_pull_tsgl the original loop wasn't updated so it may try to reassign one more page than necessary.

Add the check to the reassignment so that this does not happen.
