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

tty: goldfish: Use tty_port_destroy() to destroy port

In goldfish_tty_probe(), the port initialized through tty_port_init() should be destroyed in error paths.In goldfish_tty_remove(), qtty->port also should be destroyed or else might leak resources.

Fix the above by calling tty_port_destroy().

OESA-2025-1432 — kernel security update

2026-10-04T10:29:44.066925+00:00

Affected: openEuler:20.03-LTS-SP4: kernel

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

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

KVM: x86: Handle SRCU initialization failure during page track init

Check the return of init_srcu_struct(), which can fail due to OOM, when initializing the page track mechanism. Lack of checking leads to a NULL pointer deref found by a modified syzkaller.

[Move the call towards the beginning of kvm_arch_init_vm. - Paolo](CVE-2021-47407)

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

NFSD: prevent underflow in nfssvc_decode_writeargs()

Smatch complains:

fs/nfsd/nfsxdr.c:341 nfssvc_decode_writeargs() warn: no lower bound on 'args->len'

Change the type to unsigned to prevent this issue.(CVE-2022-49280)

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

tty: synclink_gt: Fix null-pointer-dereference in slgt_clean()

When the driver fails at alloc_hdlcdev(), and then we remove the driver module, we will get the following splat:

[ 25.065966] general protection fault, probably for non-canonical address 0xdffffc0000000182: 0000 [#1] PREEMPT SMP KASAN PTI [ 25.066914] KASAN: null-ptr-deref in range [0x0000000000000c10-0x0000000000000c17] [ 25.069262] RIP: 0010:detach_hdlc_protocol+0x2a/0x3e0 [ 25.077709] Call Trace: [ 25.077924] <TASK> [ 25.078108] unregister_hdlc_device+0x16/0x30 [ 25.078481] slgt_cleanup+0x157/0x9f0 [synclink_gt]
