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

apparmor: fix potential UAF in aa_replace_profiles

The function aa_replace_profiles was accessing udata->size after calling aa_put_loaddata(udata), causing a potential UAF.

Fixed this by saving the size to a local variable before dropping the reference.

OESA-2026-3706 — kernel security update

2026-10-04T03:51:25.553999+00:00

Affected: openEuler:22.03-LTS-SP4: kernel

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

In the Linux kernel, the following vulnerability has been resolved:net: af_can: do not leave a dangling sk pointer in can_create()On error can_create() frees the allocated sk object, but sock_init_data()has already attached it to the provided sock object. This will leave adangling sk pointer in the sock object and may cause use-after-free later.(CVE-2024-56603)

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

hdlc_ppp: sync per-proto timers before freeing hdlc state

Each PPP control protocol (LCP/IPCP/IPV6CP) embedded in struct ppp registers a timer via timer_setup(). That struct ppp is the hdlc->state allocation, which detach_hdlc_protocol() frees with kfree() in both teardown paths: unregister_hdlc_device() and the re-attach inside attach_hdlc_protocol().

The ppp proto never registered a .detach callback, so detach_hdlc_protocol() performs no timer synchronization before the kfree(). The only cancel, timer_delete(&proto->timer) in ppp_cp_event(), is partial (it does not wait for a running callback) and only runs on the ->CLOSED transition; ppp_stop()/ppp_close() do not sync either. A ppp_timer callback already executing (blocked on ppp->lock) survives the kfree and then dereferences proto->state / ppp->lock in freed memory, leading to a use-after-free.

Fix this by adding a .detach helper that calls timer_shutdown_sync() on every per-proto timer. detach_hd…
