| OpenVPN from 2.6.0 through 2.6.10 in a server role accepts multiple exit notifications from authenticated clients which will extend the validity of a closing session |
| An attacker may cause a denial of service by crafting an Accept-Language header which ParseAcceptLanguage will take significant time to parse. |
| JasPer 2.0.14 has a memory leak in base/jas_malloc.c in libjasper.a when "--output-format jp2" is used. |
| A flaw was found in the way civetweb frontend was handling requests for ceph RGW server with SSL enabled. An unauthenticated attacker could create multiple connections to ceph RADOS gateway to exhaust file descriptors for ceph-radosgw service resulting in a remote denial of service. |
| In the Linux kernel, the following vulnerability has been resolved:
ice: Fix improper handling of refcount in ice_dpll_init_rclk_pins()
This patch addresses a reference count handling issue in the
ice_dpll_init_rclk_pins() function. The function calls ice_dpll_get_pins(),
which increments the reference count of the relevant resources. However,
if the condition WARN_ON((!vsi || !vsi->netdev)) is met, the function
currently returns an error without properly releasing the resources
acquired by ice_dpll_get_pins(), leading to a reference count leak.
To resolve this, the check has been moved to the top of the function. This
ensures that the function verifies the state before any resources are
acquired, avoiding the need for additional resource management in the
error path.
This bug was identified by an experimental static analysis tool developed
by our team. The tool specializes in analyzing reference count operations
and detecting potential issues where resources are not properly managed.
In this case, the tool flagged the missing release operation as a
potential problem, which led to the development of this patch. |
| In the Linux kernel, the following vulnerability has been resolved:
netfs: Delete subtree of 'fs/netfs' when netfs module exits
In netfs_init() or fscache_proc_init(), we create dentry under 'fs/netfs',
but in netfs_exit(), we only delete the proc entry of 'fs/netfs' without
deleting its subtree. This triggers the following WARNING:
==================================================================

| In the Linux kernel, the following vulnerability has been resolved:
codetag: debug: mark codetags for poisoned page as empty
When PG_hwpoison pages are freed they are treated differently in
free_pages_prepare() and instead of being released they are isolated.
Page allocation tag counters are decremented at this point since the page
is considered not in use. Later on when such pages are released by
unpoison_memory(), the allocation tag counters will be decremented again
and the following warning gets reported:

| In the Linux kernel, the following vulnerability has been resolved:
iavf: Fix error handling in iavf_init_module()
The iavf_init_module() won't destroy workqueue when pci_register_driver()
failed. Call destroy_workqueue() when pci_register_driver() failed to
prevent the resource leak.
Similar to the handling of u132_hcd_init in commit f276e002793c
("usb: u132-hcd: fix resource leak") |
| In the Linux kernel, the following vulnerability has been resolved:
net/9p: Fix a potential socket leak in p9_socket_open
Both p9_fd_create_tcp() and p9_fd_create_unix() will call
p9_socket_open(). If the creation of p9_trans_fd fails,
p9_fd_create_tcp() and p9_fd_create_unix() will return an
error directly instead of releasing the cscoket, which will
result in a socket leak.
This patch adds sock_release() to fix the leak issue. |
| In the Linux kernel, the following vulnerability has been resolved:
gpio: amd8111: Fix PCI device reference count leak
for_each_pci_dev() is implemented by pci_get_device(). The comment of
pci_get_device() says that it will increase the reference count for the
returned pci_dev and also decrease the reference count for the input
pci_dev @from if it is not NULL.
If we break for_each_pci_dev() loop with pdev not NULL, we need to call
pci_dev_put() to decrease the reference count. Add the missing
pci_dev_put() after the 'out' label. Since pci_dev_put() can handle NULL
input parameter, there is no problem for the 'Device not found' branch.
For the normal path, add pci_dev_put() in amd_gpio_exit(). |
| In the Linux kernel, the following vulnerability has been resolved:
gpio/rockchip: fix refcount leak in rockchip_gpiolib_register()
The node returned by of_get_parent() with refcount incremented,
of_node_put() needs be called when finish using it. So add it in the
end of of_pinctrl_get(). |
| In the Linux kernel, the following vulnerability has been resolved:
net: wwan: iosm: fix memory leak in ipc_mux_init()
When failed to alloc ipc_mux->ul_adb.pp_qlt in ipc_mux_init(), ipc_mux
is not released. |
| In the Linux kernel, the following vulnerability has been resolved:
ethernet: aeroflex: fix potential skb leak in greth_init_rings()
The greth_init_rings() function won't free the newly allocated skb when
dma_mapping_error() returns error, so add dev_kfree_skb() to fix it.
Compile tested only. |
| In the Linux kernel, the following vulnerability has been resolved:
net: ipv6: ensure we call ipv6_mc_down() at most once
There are two reasons for addrconf_notify() to be called with NETDEV_DOWN:
either the network device is actually going down, or IPv6 was disabled
on the interface.
If either of them stays down while the other is toggled, we repeatedly
call the code for NETDEV_DOWN, including ipv6_mc_down(), while never
calling the corresponding ipv6_mc_up() in between. This will cause a
new entry in idev->mc_tomb to be allocated for each multicast group
the interface is subscribed to, which in turn leaks one struct ifmcaddr6
per nontrivial multicast group the interface is subscribed to.
The following reproducer will leak at least $n objects:
ip addr add ff2e::4242/32 dev eth0 autojoin
sysctl -w net.ipv6.conf.eth0.disable_ipv6=1
for i in $(seq 1 $n); do
ip link set up eth0; ip link set down eth0
done
Joining groups with IPV6_ADD_MEMBERSHIP (unprivileged) or setting the
sysctl net.ipv6.conf.eth0.forwarding to 1 (=> subscribing to ff02::2)
can also be used to create a nontrivial idev->mc_list, which will the
leak objects with the right up-down-sequence.
Based on both sources for NETDEV_DOWN events the interface IPv6 state
should be considered:
- not ready if the network interface is not ready OR IPv6 is disabled
for it
- ready if the network interface is ready AND IPv6 is enabled for it
The functions ipv6_mc_up() and ipv6_down() should only be run when this
state changes.
Implement this by remembering when the IPv6 state is ready, and only
run ipv6_mc_down() if it actually changed from ready to not ready.
The other direction (not ready -> ready) already works correctly, as:
- the interface notification triggered codepath for NETDEV_UP /
NETDEV_CHANGE returns early if ipv6 is disabled, and
- the disable_ipv6=0 triggered codepath skips fully initializing the
interface as long as addrconf_link_ready(dev) returns false
- calling ipv6_mc_up() repeatedly does not leak anything |

octeontx2-pf: Fix resource leakage in VF driver unbind
resources allocated like mcam entries to support the Ntuple feature
and hash tables for the tc feature are not getting freed in driver
unbind. This patch fixes the issue. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: SVM: fix missing sev_decommission in sev_receive_start
DECOMMISSION the current SEV context if binding an ASID fails after
RECEIVE_START. Per AMD's SEV API, RECEIVE_START generates a new guest
context and thus needs to be paired with DECOMMISSION:
The RECEIVE_START command is the only command other than the LAUNCH_START
command that generates a new guest context and guest handle.
The missing DECOMMISSION can result in subsequent SEV launch failures,
as the firmware leaks memory and might not able to allocate more SEV
guest contexts in the future.
Note, LAUNCH_START suffered the same bug, but was previously fixed by
commit 934002cd660b ("KVM: SVM: Call SEV Guest Decommission if ASID
binding fails"). |
