In the Linux kernel, the following vulnerability has been resolved:
ACPICA: Fix error code path in acpi_ds_call_control_method()
A use-after-free in acpi_ps_parse_aml() after a failing invocaion of
acpi_ds_call_control_method() is reported by KASAN [1] and code
inspection reveals that next_walk_state pushed to the thread by
acpi_ds_create_walk_state() is freed on errors, but it is not popped
from the thread beforehand. Thus acpi_ds_get_current_walk_state()
called by acpi_ps_parse_aml() subsequently returns it as the new
walk state which is incorrect.
To address this, make acpi_ds_call_control_method() call
acpi_ds_pop_walk_state() to pop next_walk_state from the thread before
returning an error. |

An attacker with adjacent access, without authentication, can exploit
this vulnerability to retrieve a hard-coded password embedded in
publicly available software. This password can then be used to decrypt
sensitive network traffic, affecting the Cognex device. |
In the Linux kernel, the following vulnerability has been resolved:
crypto: seqiv - Handle EBUSY correctly
As it is seqiv only handles the special return value of EINPROGERSS,
which means that in all other cases it will free data related to the
request.
However, as the caller of seqiv may specify MAY_BACKLOG, we also need
to expect EBUSY and treat it in the same way. Otherwise backlogged
requests will trigger a use-after-free. |

H3C devices running firmware version NX15V100R015 are vulnerable to unauthorized access due to insecure default credentials. The root user account has no password set, and the H3C user account uses the default password "admin," both stored in the /etc/shadow file. Attackers with network access can exploit these credentials to gain unauthorized root-level access to the device via the administrative interface or other network services, potentially leading to privilege escalation, information disclosure, or arbitrary code execution. |

i2c: ismt: Fix an out-of-bounds bug in ismt_access()

In the Linux kernel, the following vulnerability has been resolved:
blk-cgroup: Reinit blkg_iostat_set after clearing in blkcg_reset_stats()
When blkg_alloc() is called to allocate a blkcg_gq structure
with the associated blkg_iostat_set's, there are 2 fields within
blkg_iostat_set that requires proper initialization - blkg & sync.
The former field was introduced by commit 3b8cc6298724 ("blk-cgroup:
Optimize blkcg_rstat_flush()") while the later one was introduced by
commit f73316482977 ("blk-cgroup: reimplement basic IO stats using
cgroup rstat").
Unfortunately those fields in the blkg_iostat_set's are not properly
re-initialized when they are cleared in v1's blkcg_reset_stats(). This
can lead to a kernel panic due to NULL pointer access of the blkg
pointer. The missing initialization of sync is less problematic and
can be a problem in a debug kernel due to missing lockdep initialization.
Fix these problems by re-initializing them after memory clearing. |
In the Linux kernel, the following vulnerability has been resolved:
NFSD: fix leaked reference count of nfsd4_ssc_umount_item
The reference count of nfsd4_ssc_umount_item is not decremented
on error conditions. This prevents the laundromat from unmounting
the vfsmount of the source file.
This patch decrements the reference count of nfsd4_ssc_umount_item
on error. |
Cognex In-Sight Explorer and In-Sight Camera Firmware expose
a proprietary protocol on TCP port 1069 to perform management operations
such as modifying system properties. The user management functionality
handles sensitive data such as registered usernames and passwords over
an unencrypted channel, allowing an adjacent attacker to intercept valid
credentials to gain access to the device. |
Cognex In-Sight Explorer and In-Sight Camera Firmware expose a telnet-based service on port 23 in order to allow
management operations on the device such as firmware upgrades and device
reboot requiring an authentication. A wrong management of login
failures of the service allows a denial-of-service attack, leaving the telnet service
into an unreachable state. |
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_conn: fail SCO/ISO via hci_conn_failed if ACL gone early
Not calling hci_(dis)connect_cfm before deleting conn referred to by a
socket generally results to use-after-free.
When cleaning up SCO connections when the parent ACL is deleted too
early, use hci_conn_failed to do the connection cleanup properly.
We also need to clean up ISO connections in a similar situation when
connecting has started but LE Create CIS is not yet sent, so do it too
here. |

In the Linux kernel, the following vulnerability has been resolved:
md/raid10: fix null-ptr-deref of mreplace in raid10_sync_request
There are two check of 'mreplace' in raid10_sync_request(). In the first
check, 'need_replace' will be set and 'mreplace' will be used later if
no-Faulty 'mreplace' exists, In the second check, 'mreplace' will be
set to NULL if it is Faulty, but 'need_replace' will not be changed
accordingly. null-ptr-deref occurs if Faulty is set between two check.
Fix it by merging two checks into one. And replace 'need_replace' with
'mreplace' because their values are always the same. |

Astro-Shield is an integration to enhance website security with SubResource Integrity hashes, Content-Security-Policy headers, and other techniques. Versions from 1.2.0 to 1.3.1 of Astro-Shield allow bypass to the allow-lists for cross-origin resources by introducing valid `integrity` attributes to the injected code. This implies that the injected SRI hash would be added to the generated CSP header, which would lead the browser to believe that the injected resource is legit. This vulnerability is patched in version 1.3.2. |
Astro-Shield is a library to compute the subresource integrity hashes for your JS scripts and CSS stylesheets. When automated CSP headers generation for SSR content is enabled and the web application serves content that can be partially controlled by external users, then it is possible that the CSP headers generation feature might be "allow-listing" malicious injected resources like inlined JS, or references to external malicious scripts. The fix is available in version 1.3.0. |
