CVE ID : CVE-2025-37789

Published : May 1, 2025, 2:15 p.m. | 1 hour, 10 minutes ago

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

net: openvswitch: fix nested key length validation in the set() action

It’s not safe to access nla_len(ovs_key) if the data is smaller than
the netlink header. Check that the attribute is OK first.

CVE-2025-37791 – Dell PowerEdge ethtool Stack Corruption Vulnerability

CVE ID : CVE-2025-37791

Published : May 1, 2025, 2:15 p.m. | 1 hour, 10 minutes ago

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

ethtool: cmis_cdb: use correct rpl size in ethtool_cmis_module_poll()

rpl is passed as a pointer to ethtool_cmis_module_poll(), so the correct
size of rpl is sizeof(*rpl) which should be just 1 byte. Using the
pointer size instead can cause stack corruption:

CVE-2025-37792 – Linux Bluetooth btrtl NULL Pointer Dereference Vulnerability

CVE ID : CVE-2025-37792

Published : May 1, 2025, 2:15 p.m. | 1 hour, 10 minutes ago

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

Bluetooth: btrtl: Prevent potential NULL dereference

The btrtl_initialize() function checks that rtl_load_file() either
had an error or it loaded a zero length file. However, if it loaded
a zero length file then the error code is not set correctly. It
results in an error pointer vs NULL bug, followed by a NULL pointer
dereference. This was detected by Smatch:

drivers/bluetooth/btrtl.c:592 btrtl_initialize() warn: passing zero to ‘ERR_PTR’

CVE-2025-37793 – Intel ASoC avs Null Pointer Dereference Vulnerability

CVE ID : CVE-2025-37793

Published : May 1, 2025, 2:15 p.m. | 1 hour, 10 minutes ago

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

ASoC: Intel: avs: Fix null-ptr-deref in avs_component_probe()

devm_kasprintf() returns NULL when memory allocation fails. Currently,
avs_component_probe() does not check for this case, which results in a
NULL pointer dereference.

CVE-2025-37794 – “Qualcomm Atheros Linux Wi-Fi Driver NULL Pointer Dereference Vulnerability”

CVE ID : CVE-2025-37794

Published : May 1, 2025, 2:15 p.m. | 1 hour, 10 minutes ago

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

wifi: mac80211: Purge vif txq in ieee80211_do_stop()

After ieee80211_do_stop() SKB from vif’s txq could still be processed.
Indeed another concurrent vif schedule_and_wake_txq call could cause
those packets to be dequeued (see ieee80211_handle_wake_tx_queue())
without checking the sdata current state.

Because vif.drv_priv is now cleared in this function, this could lead to
driver crash.

For example in ath12k, ahvif is store in vif.drv_priv. Thus if
ath12k_mac_op_tx() is called after ieee80211_do_stop(), ahvif->ah can be
NULL, leading the ath12k_warn(ahvif->ah,…) call in this function to
trigger the NULL deref below.

because SDATA_STATE_RUNNING is cleared at this point).

CVE-2025-37795 – Linux Kernel wifi ath11k Use After Free

CVE ID : CVE-2025-37795

Published : May 1, 2025, 2:15 p.m. | 1 hour, 10 minutes ago

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

wifi: mac80211: Update skb’s control block key in ieee80211_tx_dequeue()

The ieee80211 skb control block key (set when skb was queued) could have
been removed before ieee80211_tx_dequeue() call. ieee80211_tx_dequeue()
already called ieee80211_tx_h_select_key() to get the current key, but
the latter do not update the key in skb control block in case it is
NULL. Because some drivers actually use this key in their TX callbacks
(e.g. ath1{1,2}k_mac_op_tx()) this could lead to the use after free
below:

CVE-2025-37796 – “Linux Kernel WiFi at76c50x Use After Free”

CVE ID : CVE-2025-37796

Published : May 1, 2025, 2:15 p.m. | 1 hour, 10 minutes ago

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

wifi: at76c50x: fix use after free access in at76_disconnect

The memory pointed to by priv is freed at the end of at76_delete_device
function (using ieee80211_free_hw). But the code then accesses the udev
field of the freed object to put the USB device. This may also lead to a
memory leak of the usb device. Fix this by using udev from interface.
