| In the Linux kernel, the following vulnerability has been resolved:
mmc: core: Add validation for host-provided max_segs
The max_segs field is of type unsigned short, and if a host driver
sets an excessively large value, it may be truncated to zero. This
can cause mmc_alloc_sg() to call kmalloc_objs() with a zero size
allocation request, which leads to undefined behavior.
Under the SLUB allocator, kmalloc(0) returns a special pointer
(ZERO_SIZE_PTR). The subsequent 'if (sg)' check will evaluate to
true, and sg_init_table() will then attempt to access invalid memory,
resulting in a crash:

To prevent this, add a validation check in mmc_mq_init_request() to
detect when sg_len (derived from max_segs) is zero. If sg_len is zero,
we return an error and print an error message, allowing host driver
developers to identify and fix incorrect max_segs configuration.
This is a defensive measure that ensures the MMC core fails gracefully
when host drivers provide invalid max_segs values, rather than crashing
with a page fault. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/gma500: return errors from Oaktrail HDMI I2C reads
xfer_read() waits for the HDMI I2C transaction to reach
I2C_TRANSACTION_DONE, but it ignores both timeout and signal returns from
wait_for_completion_interruptible_timeout(). If the interrupt never
advances the transaction state, the loop can wait forever.
Return -ETIMEDOUT when the completion wait expires, propagate interrupted
waits, and make the I2C master_xfer callback return the first transfer
error instead of reporting a successful message count. |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: ipset: mark the rcu locked areas properly
When we bump the uref counter, there's no need to keep
the rcu lock because the referred hash table can't
disappear. Also, from the same reason in mtype_gc we
need the rcu lock and not a spinlock. |
| In the Linux kernel, the following vulnerability has been resolved:
macsec: initialize SecY before registering the netdevice
Creating a MACsec device with MAC offload over an LRO-capable lower
device triggers a warning in rtmsg_ifinfo_build_skb() when IPv4
forwarding is enabled by default.
register_netdevice() invokes inetdev_init(), which disables LRO and emits
a NETDEV_FEAT_CHANGE notification. This reaches macsec_fill_info() before
macsec_add_dev() initializes the SecY. key_len is still zero, so
macsec_fill_info() returns -EMSGSIZE and trips the WARN_ON in
rtmsg_ifinfo_build_skb(), even though the skb has enough space.
Even without the warning, notifications during registration can report
uninitialized SecY attributes, including the SCI. This ordering has existed
since the driver was introduced.
Initialize the SecY and apply the new-link attributes before registration.
Move MAC address inheritance into macsec_newlink() so the SCI can also be
initialized before registration-time notifications report it. Move the
per-CPU statistics and metadata destination allocation into ndo_init(),
and release partial allocations on failure. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: adau1372: allow sleepy powerdown GPIOs
gpiod_set_value() emits a WARN when the GPIO provider indicates that it
can sleep, as is typical for I2C controlled GPIO expanders. Since the
powerdown GPIO is only manipulated in process context, use the _cansleep
variant instead. This lets the driver use sleepy GPIOs to power off the
chip. |

| Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 42.11.16, 43.8.1, 44.9.1, and 45.0.0-beta.6, Electron does not block compromised eMudhra intermediate certificates in Chromium networking, Node.js tls, Node.js https, or Node.js fetch. An attacker who holds a certificate issued through one of these intermediates and can intercept network traffic can impersonate a TLS server to an affected application. This issue is fixed in versions 42.11.16, 43.8.1, 44.9.1, and 45.0.0-beta.6. |
