| In the Linux kernel, the following vulnerability has been resolved:
wifi: ath9k: avoid uninit memory read in ath9k_htc_rx_msg()
syzbot is reporting uninit value at ath9k_htc_rx_msg() [1], for
ioctl(USB_RAW_IOCTL_EP_WRITE) can call ath9k_hif_usb_rx_stream() with
pkt_len = 0 but ath9k_hif_usb_rx_stream() uses
__dev_alloc_skb(pkt_len + 32, GFP_ATOMIC) based on an assumption that
pkt_len is valid. As a result, ath9k_hif_usb_rx_stream() allocates skb
with uninitialized memory and ath9k_htc_rx_msg() is reading from
uninitialized memory.
Since bytes accessed by ath9k_htc_rx_msg() is not known until
ath9k_htc_rx_msg() is called, it would be difficult to check minimal valid
pkt_len at "if (pkt_len > 2 * MAX_RX_BUF_SIZE) {" line in
ath9k_hif_usb_rx_stream().
We have two choices. One is to workaround by adding __GFP_ZERO so that
ath9k_htc_rx_msg() sees 0 if pkt_len is invalid. The other is to let
ath9k_htc_rx_msg() validate pkt_len before accessing. This patch chose
the latter.
Note that I'm not sure threshold condition is correct, for I can't find
details on possible packet length used by this protocol. |
| In the Linux kernel, the following vulnerability has been resolved:
HSI: ssi_protocol: fix potential resource leak in ssip_pn_open()
ssip_pn_open() claims the HSI client's port with hsi_claim_port(). When
hsi_register_port_event() gets some error and returns a negetive value,
the HSI client's port should be released with hsi_release_port().
Fix it by calling hsi_release_port() when hsi_register_port_event() fails. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: ath10k: Delay the unmapping of the buffer
On WCN3990, we are seeing a rare scenario where copy engine hardware is
sending a copy complete interrupt to the host driver while still
processing the buffer that the driver has sent, this is leading into an
SMMU fault triggering kernel panic. This is happening on copy engine
channel 3 (CE3) where the driver normally enqueues WMI commands to the
firmware. Upon receiving a copy complete interrupt, host driver will
immediately unmap and frees the buffer presuming that hardware has
processed the buffer. In the issue case, upon receiving copy complete
interrupt, host driver will unmap and free the buffer but since hardware
is still accessing the buffer (which in this case got unmapped in
parallel), SMMU hardware will trigger an SMMU fault resulting in a
kernel panic.
In order to avoid this, as a work around, add a delay before unmapping
the copy engine source DMA buffer. This is conditionally done for
WCN3990 and only for the CE3 channel where issue is seen.
Below is the crash signature:

| In the Linux kernel, the following vulnerability has been resolved:
mrp: introduce active flags to prevent UAF when applicant uninit
The caller of del_timer_sync must prevent restarting of the timer, If
we have no this synchronization, there is a small probability that the
cancellation will not be successful.

| The nbconvert tool, jupyter nbconvert, converts Jupyter notebooks to various other formats via Jinja templates. Versions of nbconvert up to and including 7.16.6 on Windows have a vulnerability in which converting a notebook containing SVG output to a PDF results in unauthorized code execution. Specifically, a third party can create a `inkscape.bat` file that defines a Windows batch script, capable of arbitrary code execution. When a user runs `jupyter nbconvert --to pdf` on a notebook containing SVG output to a PDF on a Windows platform from this directory, the `inkscape.bat` file is run unexpectedly. As of time of publication, no known patches exist. |

| igmpproxy 0.4 before commit 2b30c36 allows remote attackers to cause a denial of service (application crash) via a crafted IGMPv3 membership report packet with a malicious source address. Due to insufficient validation in the `recv_igmp()` function in src/igmpproxy.c, an invalid group record type can trigger a NULL pointer dereference when logging the address using `inet_fmtsrc()`. This vulnerability can be exploited by sending malformed multicast traffic to a host running igmpproxy, leading to a crash. igmpproxy is used in various embedded networking environments and consumer-grade IoT devices (such as home routers and media gateways) to handle multicast traffic for IPTV and other streaming services. Affected devices that rely on unpatched versions of igmpproxy may be vulnerable to remote denial-of-service attacks across a LAN . |
