Security Vulnerabilities
- CVEs Published In August 2024
In the Linux kernel, the following vulnerability has been resolved:
tpm: Use auth only after NULL check in tpm_buf_check_hmac_response()
Dereference auth after NULL check in tpm_buf_check_hmac_response().
Otherwise, unless tpm2_sessions_init() was called, a call can cause NULL
dereference, when TCG_TPM2_HMAC is enabled.
[jarkko: adjusted the commit message.]
In the Linux kernel, the following vulnerability has been resolved:
cifs: Fix server re-repick on subrequest retry
When a subrequest is marked for needing retry, netfs will call
cifs_prepare_write() which will make cifs repick the server for the op
before renegotiating credits; it then calls cifs_issue_write() which
invokes smb2_async_writev() - which re-repicks the server.
If a different server is then selected, this causes the increment of
server->in_flight to happen against one record and the decrement to happen
against another, leading to misaccounting.
Fix this by just removing the repick code in smb2_async_writev(). As this
is only called from netfslib-driven code, cifs_prepare_write() should
always have been called first, and so server should never be NULL and the
preparatory step is repeated in the event that we do a retry.
The problem manifests as a warning looking something like:
WARNING: CPU: 4 PID: 72896 at fs/smb/client/smb2ops.c:97 smb2_add_credits+0x3f0/0x9e0 [cifs]
...
RIP: 0010:smb2_add_credits+0x3f0/0x9e0 [cifs]

Which may be triggered by a number of different xfstests running against an
Azure server in multichannel mode. generic/249 seems the most repeatable,
but generic/215, generic/249 and generic/308 may also show it.
In the Linux kernel, the following vulnerability has been resolved:
ext4: use memtostr_pad() for s_volume_name
As with the other strings in struct ext4_super_block, s_volume_name is
not NUL terminated. The other strings were marked in commit 072ebb3bffe6
("ext4: add nonstring annotations to ext4.h"). Using strscpy() isn't
the right replacement for strncpy(); it should use memtostr_pad()
instead.
Access permission verification vulnerability in the content sharing pop-up module
Impact: Successful exploitation of this vulnerability may affect service confidentiality.
Access permission verification vulnerability in the Settings module.
Impact: Successful exploitation of this vulnerability may affect service confidentiality.
Access permission verification vulnerability in the Contacts module
Impact: Successful exploitation of this vulnerability may affect service confidentiality.
There is a permission and access control vulnerability of ZTE's ZXV10 XT802/ET301 product.Attackers with common permissions can log in the terminal web and change the password of the administrator illegally by intercepting requests to change the passwords.
Permission verification vulnerability in the lock screen module
Impact: Successful exploitation of this vulnerability may affect availability
The LearnPress – WordPress LMS Plugin plugin for WordPress is vulnerable to time-based SQL Injection via the 'order' parameter in all versions up to, and including, 4.2.6.9.3 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Contributor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
The Premium Addons for Elementor plugin for WordPress is vulnerable to unauthorized modification and loss of data due to a missing capability check on the 'check_temp_validity' and 'update_template_title' functions in all versions up to, and including, 4.10.38. This makes it possible for authenticated attackers, with Contributor-level access and above, to delete arbitrary content and update post and page titles.
