| In the Linux kernel, the following vulnerability has been resolved:
mm: prevent poison consumption when splitting THP
When performing memory error injection on a THP (Transparent Huge Page)
mapped to userspace on an x86 server, the kernel panics with the following
trace. The expected behavior is to terminate the affected process instead
of panicking the kernel, as the x86 Machine Check code can recover from an
in-userspace #MC.
mce: [Hardware Error]: CPU 0: Machine Check Exception: f Bank 3: bd80000000070134
mce: [Hardware Error]: RIP 10:<ffffffff8372f8bc> {memchr_inv+0x4c/0xf0}

mce: [Hardware Error]: Run the above through 'mcelog --ascii'
mce: [Hardware Error]: Machine check: Data load in unrecoverable area of kernel
Kernel panic - not syncing: Fatal local machine check
The root cause of this panic is that handling a memory failure triggered
by an in-userspace #MC necessitates splitting the THP. The splitting
process employs a mechanism, implemented in
try_to_map_unused_to_zeropage(), which reads the pages in the THP to
identify zero-filled pages. However, reading the pages in the THP results
in a second in-kernel #MC, occurring before the initial memory_failure()
completes, ultimately leading to a kernel panic. See the kernel panic
call trace on the two #MCs.
First Machine Check occurs // [1]
memory_failure() // [2]
try_to_split_thp_page()
split_huge_page()
split_huge_page_to_list_to_order()
__folio_split() // [3]
remap_page()
remove_migration_ptes()
remove_migration_pte()
try_to_map_unused_to_zeropage() // [4]
memchr_inv() // [5]
Second Machine Check occurs // [6]
Kernel panic
[1] Triggered by accessing a hardware-poisoned THP in userspace, which is
typically recoverable by terminating the affected process.
[2] Call folio_set_has_hwpoisoned() before try_to_split_thp_page().
[3] Pass the RMP_USE_SHARED_ZEROPAGE remap flag to remap_page().
[4] Try to map the unused THP to zeropage.
[5] Re-access pages in the hw-poisoned THP in the kernel.
[6] Triggered in-kernel, leading to a panic kernel.
In Step[2], memory_failure() sets the poisoned flag on the page in the THP
by TestSetPageHWPoison() before calling try_to_split_thp_page().
As suggested by David Hildenbrand, fix this panic by not accessing to the
poisoned page in the THP during zeropage identification, while continuing
to scan unaffected pages in the THP for possible zeropage mapping. This
prevents a second in-kernel #MC that would cause kernel panic in Step[4].
Thanks to Andrew Zaborowski for his initial work on fixing this issue. |
| In the Linux kernel, the following vulnerability has been resolved:
mm/damon/sysfs: dealloc commit test ctx always
The damon_ctx for testing online DAMON parameters commit inputs is
deallocated only when the test fails. This means memory is leaked for
every successful online DAMON parameters commit. Fix the leak by always
deallocating it. |
| In the Linux kernel, the following vulnerability has been resolved:
mm/damon/core: fix potential memory leak by cleaning ops_filter in damon_destroy_scheme
Currently, damon_destroy_scheme() only cleans up the filter list but
leaves ops_filter untouched, which could lead to memory leaks when a
scheme is destroyed.
This patch ensures both filter and ops_filter are properly freed in
damon_destroy_scheme(), preventing potential memory leaks. |

platform/x86: alienware-wmi-wmax: Fix NULL pointer dereference in sleep handlers
Devices without the AWCC interface don't initialize `awcc`. Add a check
before dereferencing it in sleep handlers. |
| A
CWE-611: Improper Restriction of XML External Entity Reference vulnerability exists that could
cause manipulation of SOAP API calls and XML external entities injection resulting in unauthorized file access
when the server is accessed via the network using an application account. |
| NeuVector used a hard-coded cryptographic key embedded in the source
code. At compilation time, the key value was replaced with the secret
key value and used to encrypt sensitive configurations when NeuVector
stores the data. |
| A stored XSS vulnerability in Quantum Manager component 1.0.0-3.2.0 for Joomla was discovered. File names are not properly escaped. |
| A vulnerability has been identified within Rancher where a cluster or node driver can be used to escape the chroot
jail and gain root access to the Rancher container itself. In
production environments, further privilege escalation is possible based
on living off the land within the Rancher container itself. For the test
and development environments, based on a –privileged Docker container,
it is possible to escape the Docker container and gain execution access
on the host system.
This issue affects rancher: from 2.7.0 before 2.7.16, from 2.8.0 before 2.8.9, from 2.9.0 before 2.9.3. |
| A vulnerability has been identified in which an RKE1 cluster keeps
constantly reconciling when secrets encryption configuration is enabled.
When reconciling, the Kube API secret values are written in plaintext
on the AppliedSpec. Cluster owners, Cluster members, and Project members
(for projects within the cluster), all have RBAC permissions to view
the cluster object from the apiserver. |
| A stored XSS vulnerability in Quantum Manager component 1.0.0-3.2.0 for Joomla was discovered. The SVG upload feature does not sanitize uploads. |
| When a Java command with password parameters is executed and terminated by NeuVector for Process rule violation the password will appear in the NeuVector security event log. |
| A vulnerability has been identified within Rancher that can be exploited
in narrow circumstances through a man-in-the-middle (MITM) attack. An
attacker would need to have control of an expired domain or execute a
DNS spoofing/hijacking attack against the domain to exploit this
vulnerability. The targeted domain is the one used as the Rancher URL. |

| Stakater Forecastle 1.0.139 and before allows %5C../ directory traversal in the website component. |
| A misconfigured access token mechanism in the Unifi Protect Application (Version 5.3.41 and earlier) could permit the recipient of a "Share Livestream" link to maintain access to the corresponding livestream subsequent to such link becoming disabled. |
| The Flex Mag - Responsive WordPress News Theme theme for WordPress is vulnerable to unauthorized modification of data that can lead to a denial of service due to a missing capability check on the propanel_of_ajax_callback() function in all versions up to, and including, 3.5.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary option values on the WordPress site. This can be leveraged to delete an option that would create an error on the site and deny service to legitimate users. |
