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

net: usb: rtl8150: fix use-after-free in rtl8150_start_xmit()

syzbot reported a KASAN slab-use-after-free read in rtl8150_start_xmit() when accessing skb->len for tx statistics after usb_submit_urb() has been called:

BUG: KASAN: slab-use-after-free in rtl8150_start_xmit+0x71f/0x760 drivers/net/usb/rtl8150.c:712 Read of size 4 at addr ffff88810eb7a930 by task kworker/0:4/5226

The URB completion handler write_bulk_callback() frees the skb via dev_kfree_skb_irq(dev->tx_skb). The URB may complete on another CPU in softirq context before usb_submit_urb() returns in the submitter, so by the time the submitter reads skb->len the skb has already been queued to the per-CPU completion_queue and freed by net_tx_action():

CPU A (xmit) CPU B (USB completion softirq) ------------ ------------------------------ dev->tx_skb = skb; usb_submit_urb() --+ |-------> write_bulk_callback() | dev_kfree_skb_irq(dev->tx_skb) | net_tx_action() | napi_skb_cache_put() <-- free netdev->stats.tx_bytes | += skb->len; <-- UAF read

Fix it by caching skb->len before submitting the URB and using the cached value when updating the tx_bytes counter.

The pre-existing tx_bytes semantics are preserved: the counter tracks the origina…

OESA-2026-4039 — kernel security update

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:ALSA: caiaq: Use snd_card_free_when_closed() at disconnectionThe USB disconnect callback is supposed to be short and not too-longwaiting. OTOH, the current code uses snd_card_free() atdisconnection, but this waits for the close of all used fds, hence itcan take long. It eventually blocks the upper layer USB ioctls, whichmay trigger a soft lockup.An easy workaround is to replace snd_card_free() withsnd_card_free_when_closed(). This variant returns immediately whilethe release of resources is done asynchronously by the card devicerelease at the last close.This patch also splits the code to the disconnect and the free phases;the former is called immediately at the USB disconnect callback whilethe latter is called from the card destructor.(CVE-2024-56531)

In the Linux kernel, the following vulnerability has been resolved:xsk: fix OOB map writes when deleting elementsJordy says: In the xsk_map_delete_elem function an unsigned integer(map->max_entries) is compared with a user-controlled signed integer(k). Due to implicit type conversion, a large unsigned value formap->max_entries can bypass the intended bounds check: if (k >= map->max_entries) return -EINVAL;This allows k to hold a negative value (between -2147483648 and -2),which is then used as an array index in m->xsk_map[k], which resultsin an out-of-bounds access. spi…
