| In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: DR, fix memory leak in mlx5dr_cmd_create_reformat_ctx
when mlx5_cmd_exec failed in mlx5dr_cmd_create_reformat_ctx, the memory
pointed by 'in' is not released, which will cause memory leak. Move memory
release after mlx5_cmd_exec. |
| In the Linux kernel, the following vulnerability has been resolved:
Fix memory leak in posix_clock_open()
If the clk ops.open() function returns an error, we don't release the
pccontext we allocated for this clock.
Re-organize the code slightly to make it all more obvious. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: mpt3sas: Fix possible resource leaks in mpt3sas_transport_port_add()
In mpt3sas_transport_port_add(), if sas_rphy_add() returns error,
sas_rphy_free() needs be called to free the resource allocated in
sas_end_device_alloc(). Otherwise a kernel crash will happen:

tipc: fix an information leak in tipc_topsrv_kern_subscr
Use a 8-byte write to initialize sub.usr_handle in
tipc_topsrv_kern_subscr(), otherwise four bytes remain uninitialized
when issuing setsockopt(..., SOL_TIPC, ...).
This resulted in an infoleak reported by KMSAN when the packet was

The problem was that when an error occurred before handlers registration
and after allocating `new_smi->si_sm`, the variable wouldn't be freed in
the error handling afterwards since `shutdown_smi()` hadn't been
registered yet. Fix it by adding a `kfree()` in the error handling path
in `try_smi_init()`. |
| In the Linux kernel, the following vulnerability has been resolved:
fbdev: fbcon: release buffer when fbcon_do_set_font() failed
syzbot is reporting memory leak at fbcon_do_set_font() [1], for
commit a5a923038d70 ("fbdev: fbcon: Properly revert changes when
vc_resize() failed") missed that the buffer might be newly allocated
by fbcon_set_font(). |
| In the Linux kernel, the following vulnerability has been resolved:
platform/x86: mxm-wmi: fix memleak in mxm_wmi_call_mx[ds|mx]()
The ACPI buffer memory (out.pointer) returned by wmi_evaluate_method()
is not freed after the call, so it leads to memory leak.
The method results in ACPI buffer is not used, so just pass NULL to
wmi_evaluate_method() which fixes the memory leak. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: Fix memory leak in hpd_rx_irq_create_workqueue()
If construction of the array of work queues to handle hpd_rx_irq offload
work fails, we need to unwind. Destroy all the created workqueues and
the allocated memory for the hpd_rx_irq_offload_work_queue struct array. |
| In the Linux kernel, the following vulnerability has been resolved:
ext4: fix potential memory leak in ext4_fc_record_regions()
As krealloc may return NULL, in this case 'state->fc_regions' may not be
freed by krealloc, but 'state->fc_regions' already set NULL. Then will
lead to 'state->fc_regions' memory leak. |
| In the Linux kernel, the following vulnerability has been resolved:
staging: rtl8723bs: fix a potential memory leak in rtw_init_cmd_priv()
In rtw_init_cmd_priv(), if `pcmdpriv->rsp_allocated_buf` is allocated
in failure, then `pcmdpriv->cmd_allocated_buf` will be not properly
released. Besides, considering there are only two error paths and the
first one can directly return, so we do not need implicitly jump to the
`exit` tag to execute the error handler.
So this patch added `kfree(pcmdpriv->cmd_allocated_buf);` on the error
path to release the resource and simplified the return logic of
rtw_init_cmd_priv(). As there is no proper device to test with, no runtime
testing was performed. |
| In the Linux kernel, the following vulnerability has been resolved:
perf/smmuv3: Fix hotplug callback leak in arm_smmu_pmu_init()
arm_smmu_pmu_init() won't remove the callback added by
cpuhp_setup_state_multi() when platform_driver_register() failed. Remove
the callback by cpuhp_remove_multi_state() in fail path.
Similar to the handling of arm_ccn_init() in commit 26242b330093 ("bus:
arm-ccn: Prevent hotplug callback leak") |
| In the Linux kernel, the following vulnerability has been resolved:
espintcp: fix skb leaks
A few error paths are missing a kfree_skb. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: csa unmap use uninterruptible lock
After process exit to unmap csa and free GPU vm, if signal is accepted
and then waiting to take vm lock is interrupted and return, it causes
memory leaking and below warning backtrace.
Change to use uninterruptible wait lock fix the issue.

| Okta Java Management SDK facilitates interactions with the Okta management API. In versions 21.0.0 through 24.0.0, specific multithreaded implementations may encounter memory issues as threads are not properly cleaned up after requests are completed. Over time, this can degrade performance and availability in long-running applications and may result in a denial-of-service condition under sustained load. In addition to using the affected versions, users may be at risk if they are implementing a long-running application using the ApiClient in a multi-threaded manner. This issue is fixed in version 24.0.1. |
| Buffer Overflow vulnerability in libpng 1.6.43-1.6.46 allows a local attacker to cause a denial of service via png_create_read_struct() function. |
| In the Linux kernel, the following vulnerability has been resolved:
blk-iolatency: Fix memory leak on add_disk() failures
When a gendisk is successfully initialized but add_disk() fails such as when
a loop device has invalid number of minor device numbers specified,
blkcg_init_disk() is called during init and then blkcg_exit_disk() during
error handling. Unfortunately, iolatency gets initialized in the former but
doesn't get cleaned up in the latter.
This is because, in non-error cases, the cleanup is performed by
del_gendisk() calling rq_qos_exit(), the assumption being that rq_qos
policies, iolatency being one of them, can only be activated once the disk
is fully registered and visible. That assumption is true for wbt and iocost,
but not so for iolatency as it gets initialized before add_disk() is called.
It is desirable to lazy-init rq_qos policies because they are optional
features and add to hot path overhead once initialized - each IO has to walk
all the registered rq_qos policies. So, we want to switch iolatency to lazy
init too. However, that's a bigger change. As a fix for the immediate
problem, let's just add an extra call to rq_qos_exit() in blkcg_exit_disk().
This is safe because duplicate calls to rq_qos_exit() become noop's. |
