Bluetooth: hci_sync: Fix UAF in le_read_features_complete
This fixes the following backtrace caused by hci_conn being freed
before le_read_features_complete but after
hci_le_read_remote_features_sync so hci_conn_del -> hci_cmd_sync_dequeue
is not able to prevent it:

| css_parser is a Ruby CSS parser. Prior to 2.1.0 and 1.22.0, the CSS Parser gem does not validate HTTPS connections, allowing a Man-in-the-Middle (MITM) attacker to inject or modify CSS content when stylesheets are loaded via HTTPS. The connection is established with OpenSSL::SSL::VERIFY_NONE, meaning any HTTPS certificate—even entirely untrusted—will be accepted without validation. This vulnerability is fixed in 2.1.0 and 1.22.0. |
| In the Linux kernel, the following vulnerability has been resolved:
media: i2c: ov5647: Initialize subdev before controls
In ov5647_init_controls() we call v4l2_get_subdevdata, but it is
initialized by v4l2_i2c_subdev_init() in the probe, which currently
happens after init_controls(). This can result in a segfault if the
error condition is hit, and we try to access i2c_client, so fix the
order. |
| In the Linux kernel, the following vulnerability has been resolved:
net: nexthop: fix percpu use-after-free in remove_nh_grp_entry
When removing a nexthop from a group, remove_nh_grp_entry() publishes
the new group via rcu_assign_pointer() then immediately frees the
removed entry's percpu stats with free_percpu(). However, the
synchronize_net() grace period in the caller remove_nexthop_from_groups()
runs after the free. RCU readers that entered before the publish still
see the old group and can dereference the freed stats via
nh_grp_entry_stats_inc() -> get_cpu_ptr(nhge->stats), causing a
use-after-free on percpu memory.
Fix by deferring the free_percpu() until after synchronize_net() in the
caller. Removed entries are chained via nh_list onto a local deferred
free list. After the grace period completes and all RCU readers have
finished, the percpu stats are safely freed. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/panthor: fix for dma-fence safe access rules
Commit 506aa8b02a8d6 ("dma-fence: Add safe access helpers and document
the rules") details the dma-fence safe access rules. The most common
culprit is that drm_sched_fence_get_timeline_name may race with
group_free_queue. |
| Use-after-free in the JavaScript: WebAssembly component. This vulnerability was fixed in Firefox 150.0.3. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: SVM: Set/clear CR8 write interception when AVIC is (de)activated
Explicitly set/clear CR8 write interception when AVIC is (de)activated to
fix a bug where KVM leaves the interception enabled after AVIC is
activated. E.g. if KVM emulates INIT=>WFS while AVIC is deactivated, CR8
will remain intercepted in perpetuity.
On its own, the dangling CR8 intercept is "just" a performance issue, but
combined with the TPR sync bug fixed by commit d02e48830e3f ("KVM: SVM:
Sync TPR from LAPIC into VMCB::V_TPR even if AVIC is active"), the danging
intercept is fatal to Windows guests as the TPR seen by hardware gets
wildly out of sync with reality.
Note, VMX isn't affected by the bug as TPR_THRESHOLD is explicitly ignored
when Virtual Interrupt Delivery is enabled, i.e. when APICv is active in
KVM's world. I.e. there's no need to trigger update_cr8_intercept(), this
is firmly an SVM implementation flaw/detail.
WARN if KVM gets a CR8 write #VMEXIT while AVIC is active, as KVM should
never enter the guest with AVIC enabled and CR8 writes intercepted.

| LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. From 1.0.9 to before 1.6.57, passing a pointer obtained from png_get_PLTE, png_get_tRNS, or png_get_hIST back into the corresponding setter on the same png_struct/png_info pair causes the setter to read from freed memory and copy its contents into the replacement buffer. The setter frees the internal buffer before copying from the caller-supplied pointer, which now dangles. The freed region may contain stale data (producing silently corrupted chunk metadata) or data from subsequent heap allocations (leaking unrelated heap contents into the chunk struct). This vulnerability is fixed in 1.6.57. |
| In the Linux kernel, the following vulnerability has been resolved:
md/bitmap: fix GPF in write_page caused by resize race
A General Protection Fault occurs in write_page() during array resize:
RIP: 0010:write_page+0x22b/0x3c0 [md_mod]
This is a use-after-free race between bitmap_daemon_work() and
__bitmap_resize(). The daemon iterates over `bitmap->storage.filemap`
without locking, while the resize path frees that storage via
md_bitmap_file_unmap(). `quiesce()` does not stop the md thread,
allowing concurrent access to freed pages.
Fix by holding `mddev->bitmap_info.mutex` during the bitmap update. |
| In the Linux kernel, the following vulnerability has been resolved:
HID: magicmouse: Do not crash on missing msc->input
Fake USB devices can send their own report descriptors for which the
input_mapping() hook does not get called. In this case, msc->input stays NULL,
leading to a crash at a later time.
Detect this condition in the input_configured() hook and reject the device.
This is not supposed to happen with actual magic mouse devices, but can be
provoked by imposing as a magic mouse USB device. |
| In the Linux kernel, the following vulnerability has been resolved:
HID: hid-pl: handle probe errors
Errors in init must be reported back or we'll
follow a NULL pointer the first time FF is used. |
| In the Linux kernel, the following vulnerability has been resolved:
xfs: remove xfs_attr_leaf_hasname
The calling convention of xfs_attr_leaf_hasname() is problematic, because
it returns a NULL buffer when xfs_attr3_leaf_read fails, a valid buffer
when xfs_attr3_leaf_lookup_int returns -ENOATTR or -EEXIST, and a
non-NULL buffer pointer for an already released buffer when
xfs_attr3_leaf_lookup_int fails with other error values.
Fix this by simply open coding xfs_attr_leaf_hasname in the callers, so
that the buffer release code is done by each caller of
xfs_attr3_leaf_read. |
| In the Linux kernel, the following vulnerability has been resolved:
mfd: core: Add locking around 'mfd_of_node_list'
Manipulating a list in the kernel isn't safe without some sort of
mutual exclusion. Add a mutex any time we access / modify
'mfd_of_node_list' to prevent possible crashes. |
| When a BIG-IP DNS profile enabled with DNS cache is configured on a virtual server, undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. |
| An untrusted pointer dereference in the ionic cloud driver for VMWare ESXi could allow an attacker with an unprivileged VM to read kernel memory or co-located guest VM memory, potentially resulting in loss of confidentiality or availability. |
| electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. From versions 3.0.6 to before 3.8.15, electerm is vulnerable to arbitrary local code execution via deep links, CLI --opts, or crafted shortcuts. Exploit requires clicking a crafted electerm://... link or opening a crafted shortcut/command that launches electerm with attacker-controlled opts. This issue has been patched in version 3.8.15. |
| Untrusted pointer dereference for some Intel(R) QuickAssist Adapter 8960 software before version 1.13 within Ring 3: User Applications may allow an escalation of privilege. Unprivileged software adversary with an authenticated user combined with a low complexity attack may enable escalation of privilege. 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 (high), integrity (high) 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:
drm/amdgpu: fix NULL pointer issue buffer funcs
If SDMA block not enabled, buffer_funcs will not initialize,
fix the null pointer issue if buffer_funcs not initialized. |
| In the Linux kernel, the following vulnerability has been resolved:
reset: gpio: suppress bind attributes in sysfs
This is a special device that's created dynamically and is supposed to
stay in memory forever. We also currently don't have a devlink between
it and the actual reset consumer. Suppress sysfs bind attributes so that
user-space can't unbind the device because - as of now - it will cause a
use-after-free splat from any user that puts the reset control handle. |
| Use after free in Views in Google Chrome prior to 148.0.7778.96 allowed a remote attacker who had compromised the renderer process to bypass site isolation via a crafted HTML page. (Chromium security severity: High) |
