| In the Linux kernel, the following vulnerability has been resolved:
net: genl: fix error path memory leak in policy dumping
If construction of the array of policies fails when recording
non-first policy we need to unwind.
netlink_policy_dump_add_policy() itself also needs fixing as
it currently gives up on error without recording the allocated
pointer in the pstate pointer. |
| In the Linux kernel, the following vulnerability has been resolved:
net/sunrpc: fix potential memory leaks in rpc_sysfs_xprt_state_change()
The issue happens on some error handling paths. When the function
fails to grab the object `xprt`, it simply returns 0, forgetting to
decrease the reference count of another object `xps`, which is
increased by rpc_sysfs_xprt_kobj_get_xprt_switch(), causing refcount
leaks. Also, the function forgets to check whether `xps` is valid
before using it, which may result in NULL-dereferencing issues.
Fix it by adding proper error handling code when either `xprt` or
`xps` is NULL. |
| In the Linux kernel, the following vulnerability has been resolved:
octeontx2-af: Fix mcam entry resource leak
The teardown sequence in FLR handler returns if no NIX LF
is attached to PF/VF because it indicates that graceful
shutdown of resources already happened. But there is a
chance of all allocated MCAM entries not being freed by
PF/VF. Hence free mcam entries even in case of detached LF. |
| In the Linux kernel, the following vulnerability has been resolved:
interconnect: exynos: fix node leak in probe PM QoS error path
Make sure to add the newly allocated interconnect node to the provider
before adding the PM QoS request so that the node is freed on errors. |
| In the Linux kernel, the following vulnerability has been resolved:
interconnect: fix mem leak when freeing nodes
The node link array is allocated when adding links to a node but is not
deallocated when nodes are destroyed. |
| In the Linux kernel, the following vulnerability has been resolved:
powerpc/iommu: fix memory leak with using debugfs_lookup()
When calling debugfs_lookup() the result must have dput() called on it,
otherwise the memory will leak over time. To make things simpler, just
call debugfs_lookup_and_remove() instead which handles all of the logic
at once. |
| In the Linux kernel, the following vulnerability has been resolved:
net: usb: lan78xx: Limit packet length to skb->len
Packet length retrieved from descriptor may be larger than
the actual socket buffer length. In such case the cloned
skb passed up the network stack will leak kernel memory contents.
Additionally prevent integer underflow when size is less than
ETH_FCS_LEN. |
| In the Linux kernel, the following vulnerability has been resolved:
octeontx2-vf: Add missing free for alloc_percpu
Add the free_percpu for the allocated "vf->hw.lmt_info" in order to avoid
memory leak, same as the "pf->hw.lmt_info" in
`drivers/net/ethernet/marvell/octeontx2/nic/otx2_pf.c`. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: scsi_dh_alua: Fix memleak for 'qdata' in alua_activate()
If alua_rtpg_queue() failed from alua_activate(), then 'qdata' is not
freed, which will cause following memleak:

| Uncontrolled resource consumption for some Gaudi software before version 1.21.0 within Ring 3: User Applications may allow a denial of service. System software adversary with an authenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts. |
| In the Linux kernel, the following vulnerability has been resolved:
net: ngbe: fix memory leak in ngbe_probe() error path
When ngbe_sw_init() is called, memory is allocated for wx->rss_key
in wx_init_rss_key(). However, in ngbe_probe() function, the subsequent
error paths after ngbe_sw_init() don't free the rss_key. Fix that by
freeing it in error path along with wx->mac_table.
Also change the label to which execution jumps when ngbe_sw_init()
fails, because otherwise, it could lead to a double free for rss_key,
when the mac_table allocation fails in wx_sw_init(). |

thunderbolt: Fix memory leak in margining
Memory for the usb4->margining needs to be relased for the upstream port
of the router as well, even though the debugfs directory gets released
with the router device removal. Fix this. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: dwc2: fix a devres leak in hw_enable upon suspend resume
Each time the platform goes to low power, PM suspend / resume routines
call: __dwc2_lowlevel_hw_enable -> devm_add_action_or_reset().
This adds a new devres each time.
This may also happen at runtime, as dwc2_lowlevel_hw_enable() can be
called from udc_start().
This can be seen with tracing:
- echo 1 > /sys/kernel/debug/tracing/events/dev/devres_log/enable
- go to low power
- cat /sys/kernel/debug/tracing/trace
A new "ADD" entry is found upon each low power cycle:
... devres_log: 49000000.usb-otg ADD 82a13bba devm_action_release (8 bytes)
... devres_log: 49000000.usb-otg ADD 49889daf devm_action_release (8 bytes)
...
A second issue is addressed here:
- regulator_bulk_enable() is called upon each PM cycle (suspend/resume).
- regulator_bulk_disable() never gets called.
So the reference count for these regulators constantly increase, by one
upon each low power cycle, due to missing regulator_bulk_disable() call
in __dwc2_lowlevel_hw_disable().
The original fix that introduced the devm_add_action_or_reset() call,
fixed an issue during probe, that happens due to other errors in
dwc2_driver_probe() -> dwc2_core_reset(). Then the probe fails without
disabling regulators, when dr_mode == USB_DR_MODE_PERIPHERAL.
Rather fix the error path: disable all the low level hardware in the
error path, by using the "hsotg->ll_hw_enabled" flag. Checking dr_mode
has been introduced to avoid a dual call to dwc2_lowlevel_hw_disable().
"ll_hw_enabled" should achieve the same (and is used currently in the
remove() routine). |
| containerd is an open-source container runtime. Versions 1.7.28 and below, 2.0.0-beta.0 through 2.0.6, 2.1.0-beta.0 through 2.1.4, and 2.2.0-beta.0 through 2.2.0-rc.1 contain a bug in the CRI Attach implementation where a user can exhaust memory on the host due to goroutine leaks. This issue is fixed in versions 1.7.29, 2.0.7, 2.1.5 and 2.2.0. To workaround this vulnerability, users can set up an admission controller to control accesses to pods/attach resources. |
| In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix inode list leak during backref walking at resolve_indirect_refs()
During backref walking, at resolve_indirect_refs(), if we get an error
we jump to the 'out' label and call ulist_free() on the 'parents' ulist,
which frees all the elements in the ulist - however that does not free
any inode lists that may be attached to elements, through the 'aux' field
of a ulist node, so we end up leaking lists if we have any attached to
the unodes.
Fix this by calling free_leaf_list() instead of ulist_free() when we exit
from resolve_indirect_refs(). The static function free_leaf_list() is
moved up for this to be possible and it's slightly simplified by removing
unnecessary code. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/rxe: Fix mr leak in RESPST_ERR_RNR
rxe_recheck_mr() will increase mr's ref_cnt, so we should call rxe_put(mr)
to drop mr's ref_cnt in RESPST_ERR_RNR to avoid below warning:

| In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix ulist leaks in error paths of qgroup self tests
In the test_no_shared_qgroup() and test_multiple_refs() qgroup self tests,
if we fail to add the tree ref, remove the extent item or remove the
extent ref, we are returning from the test function without freeing the
"old_roots" ulist that was allocated by the previous calls to
btrfs_find_all_roots(). Fix that by calling ulist_free() before returning. |
| In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix inode list leak during backref walking at find_parent_nodes()
During backref walking, at find_parent_nodes(), if we are dealing with a
data extent and we get an error while resolving the indirect backrefs, at
resolve_indirect_refs(), or in the while loop that iterates over the refs
in the direct refs rbtree, we end up leaking the inode lists attached to
the direct refs we have in the direct refs rbtree that were not yet added
to the refs ulist passed as argument to find_parent_nodes(). Since they
were not yet added to the refs ulist and prelim_release() does not free
the lists, on error the caller can only free the lists attached to the
refs that were added to the refs ulist, all the remaining refs get their
inode lists never freed, therefore leaking their memory.
Fix this by having prelim_release() always free any attached inode list
to each ref found in the rbtree, and have find_parent_nodes() set the
ref's inode list to NULL once it transfers ownership of the inode list
to a ref added to the refs ulist passed to find_parent_nodes(). |
