In the Linux kernel, the following vulnerability has been resolved:
sched/membarrier: reduce the ability to hammer on sysmembarrier
On some systems, sysmembarrier can be very expensive, causing overall slowdowns for everything. So put a lock on the path in order to serialize the accesses to prevent the ability for this to be called at too high of a frequency and saturate the machine.
In the Linux kernel, the following vulnerability has been resolved:
tty: ngsm: require CAPNETADMIN to attach NGSM0710 ldisc
Any unprivileged user can attach NGSM0710 ldisc, but it requires CAPNETADMIN to create a GSM network anyway.
Require initial namespace CAPNETADMIN to do that.
An issue was discovered in Qt before 5.15.15, 6.x before 6.2.9, and 6.3.x through 6.5.x before 6.5.2. Certificate validation for TLS does not always consider whether the root of a chain is a configured CA certificate.
Accounts. A privacy issue was addressed with improved private data redaction for log entries.
A Speculative Race Condition (SRC) vulnerability that impacts modern CPU architectures supporting speculative execution (related to Spectre V1) has been disclosed. An unauthenticated attacker can exploit this vulnerability to disclose arbitrary data from the CPU using race conditions to access the speculative executable code paths.
Impact
The REXML gem before 3.3.2 has some DoS vulnerabilities when it parses an XML that has many specific characters such as whitespace character, >] and ]>.
If you need to parse untrusted XMLs, you may be impacted to these vulnerabilities.
Patches
The REXML gem 3.3.3 or later include the patches to fix these vulnerabilities.
Workarounds
Don't parse untrusted XMLs.
