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

smb: client: fix potential cfid UAF in smb2_query_info_compound

When smb2_query_info_compound() retries, a previously allocated cfid may have been freed in the first attempt. Because cfid wasn't reset on replay, later cleanup could act on a stale pointer, leading to a potential use-after-free.

Reinitialize cfid to NULL under the replay label.

 https://cve.radiocsirt.org/vuln/oesa-2026-1303 OESA-2026-1303 — kernel security update 2026-10-02T15:51:26.495044+00:00

Affected: openEuler:24.03-LTS: kernel

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

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

ptr_ring: do not block hard interrupts in ptr_ring_resize_multiple()

Jakub added a lockdep_assert_no_hardirq() check in __page_pool_put_page() to increase test coverage.

syzbot found a splat caused by hard irq blocking in ptr_ring_resize_multiple() [1]

As current users of ptr_ring_resize_multiple() do not require hard irqs being masked, replace it to only block BH.

Rename helpers to better reflect they are safe against BH only.

- ptr_ring_resize_multiple() to ptr_ring_resize_multiple_bh() - skb_array_resize_multiple() to skb_array_resize_multiple_bh()
