The LuckyWP Table of Contents plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘Header Title' field in all versions up to and including 2.1.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

The Element Pack Elementor Addons (Header Footer, Template Library, Dynamic Grid & Carousel, Remote Arrows) plugin for WordPress is vulnerable to Form Submission Admin Email Bypass in all versions up to, and including, 5.6.3. This is due to the plugin not properly checking for all variations of an administrators emails. This makes it possible for unauthenticated attackers to bypass the restriction using a +value when submitting the contact form.

In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Fix a memory leak in an error path of qla2x00_process_els()
Commit 8c0eb596baa5 ("[SCSI] qla2xxx: Fix a memory leak in an error path of
qla2x00_process_els()"), intended to change:
bsg_job->request->msgcode == FC_BSG_HST_ELS_NOLOGIN
bsg_job->request->msgcode != FC_BSG_RPT_ELS
but changed it to:
bsg_job->request->msgcode == FC_BSG_RPT_ELS
instead.
Change the == to a != to avoid leaking the fcport structure or freeing
unallocated memory.

The NextScripts: Social Networks Auto-Poster plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 4.4.3. This is due to missing or incorrect nonce validation on the nxssnap-reposter page. This makes it possible for unauthenticated attackers to delete arbitrary posts or pages via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The NextScripts: Social Networks Auto-Poster plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the HTTP_USER_AGENT header in all versions up to, and including, 4.4.3 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires the victim to select view "All Cron Events" in order for the injection to fire.

In the Linux kernel, the following vulnerability has been resolved:
userfaultfd: fix a race between writeprotect and exit_mmap()
A race is possible when a process exits, its VMAs are removed by
exit_mmap() and at the same time userfaultfd_writeprotect() is called.
The race was detected by KASAN on a development kernel, but it appears
to be possible on vanilla kernels as well.
Use mmget_not_zero() to prevent the race as done in other userfaultfd
operations.

In the Linux kernel, the following vulnerability has been resolved:
mm/mempolicy: do not allow illegal MPOL_F_NUMA_BALANCING | MPOL_LOCAL in mbind()
syzbot reported access to unitialized memory in mbind() [1]
Issue came with commit bda420b98505 ("numa balancing: migrate on fault
among multiple bound nodes")
This commit added a new bit in MPOL_MODE_FLAGS, but only checked valid
combination (MPOL_F_NUMA_BALANCING can only be used with MPOL_BIND) in
do_set_mempolicy()
This patch moves the check in sanitize_mpol_flags() so that it is also
used by mbind()

In the Linux kernel, the following vulnerability has been resolved:
mm/secretmem: fix NULL page->mapping dereference in page_is_secretmem()
Check for a NULL page->mapping before dereferencing the mapping in
page_is_secretmem(), as the page's mapping can be nullified while gup()
is running, e.g. by reclaim or truncation.
